Figure 4.1 - Combustible Material and Service Clearances Access Side [1- F-e-- I DI Location Recommendations 1. When locating the heater, consider general space and heating requirements, availability of gas and electrical supply, and proximity to vent locations. 2. Avoid installing units in extremely drafty locations. Drafts can cause burner flames to impinge on heat exchangers which shortens life. Maintain separation between units so discharge from one unit will not be directed into the inlet of another. 3. Be sure the structural support at the unit location site is adequate to support the unit's weight. For proper operation the unit must be installed in a level horizontal position. 4. Do not install units in locations where the flue products can be drawn into the adjacent building openings such as windows, fresh air intakes, etc. 5. Be sure that the minimum clearances to combustible materials and recommended service clearances are maintained. Units are designed for installation on non- combustible surfaces with the minimum clearances shown ln Figure 4.1 and Tables 4.1 and 4,2. 6. Units exposed to inlet air temperatures of 40"F or less, may experience condensation, therefore, provisions should be made for disposal of condensate. 7. When locating units, it is important to consider that the exhaust vent piping must be connected to the outside atmosphere. 8. Maximum equivalent vent lengths are listed in "Section A - Generai lnstruction - All Units" of the Venting lnstructions. 4 Table 4.1 - Combustible Material Clearances O ,:!' Provide sufficient room around the heater to allow for proper combustion and operation of fan. Free area around the heater must not be less than 1-1i2 times the discharge area of the unit.

A confined space is 50 cubic feet or less per 1,000 BtuiHr input of the installed appliance(s). Unlts installed in tightly sealed buildings or confined spaces must be provided with two permanent openings, one near the top of the confined space and one near the bottom. Each opening should have a free area of not less than one square inch per 1,000 BTU per hour of the total input rating off all units in the enclosure, freely communicating with interior areas having, in turn adequate infiltration from the outside. For further details on supplying combustion air to a confined (tightly sealed) space or unconfined space, see the National Fuel Gas Code ANSI 2223.1 (NFPA 54) or CSA-8149.1 lnstallation Code - latest edition. Sound and Vibration Levels Ail standard mechanical equipment generates some sound and vibration that may require attenuation. Libraries, private offices and hospital facilities will require more attenuation, and in such cases, an acoustical consultant may be retained to assist in the application. Locating the equipment away from the critical area is desirable within ducting llmitations. Generally, a unit should be located within 15' of a primary support beam. Smaller deflections typically result in reduced vibration and noise transmission. '1 . Clearances to cornbustible materials are critical. Be sure to follow all listed requirements. 2. Heaters are designed for use in heating applications with ambient startup temperatures between -40"F and 90"F and ambient operating temperatures between 40"F and 90'F. 3. Do not install unit outdoors. 4. ln garages or other sections of aircraft hangars such as offices and shops that communicate with areas used for servicing or storage, keep the bottom of the unit at least 7' above the floor unless the unit is properly guarded. ln parking garages, the unit must be installed in accordance with the standard for parking structures ANSIINFPA 88A - latest edition, and in repair garages the standard for repair garages NFPA 30A - latest edition (formerly NFPA 888). In Canada, installation of heaters in airplane hangars must be in accordance with the requirements of the enforcing authority, and in public garages in accordance with the current CSA-B1 49 codes. 5. ln aircraft hangars, keep the bottom of the unit at least '10' from the highest surface of the wings or engine enclosure of the highest aircraft housed in the hangars and in accordance with the requirements of the enlorcing authority and/or NFPA 409 - latest edition. 6. Installation of units in high humidity or salt water atmospheres will cause accelerated corrosion resulting in a reduction of the normal life of the units.

All standard units are shipped fully boxed. Larger units are also supplied with skid suppods on the bottom of the box. The larger units may be lifted from the bottom by means of a fork lift or other lifting device only if the shipping support skids are left in place and the forks support the whole depth of the unit. lf the unit must be lifted from the bottom for final installation without the carton in place, be sure to properly support the unit over its entire length and width to prevent damage. When lifting units, make sure the load is balanced. 5. Propeller models up to size 350 have 2 mounting holes, size 350 and above have 4 mounting holes and blower models up to size 350 have 4 mounting holes, size 350 and above have 6 mounting holes. Units with two point suspension incorporate a level hanging feature. Depending on what options and accessories are being used, the heater may not hang level as recieved from the factory. Do not hang heaters with deflector hoods until referring to the "lnstallation Manual for Deflector Hoods" and making the recommended preliminary adjustments on the heater, while the heater is resting on the floor. The units can be mounted with 318'-'16 threaded rod as follows: . On each piece of threaded rod used, screw a nut a distance of about 1" onto the end of the threaded rods that will be screwed into the unit heater. . Place a washer over the end of the threaded rod and screw the threaded rod into the unit heater weld nuts on the top of the heater at least 5 turns. and no more than 10 turns. Tighten the nut first installed onto the threaded rod to prevent the rod from turning. . Drill holes into a steel channel or angle iron at the same center-line dimensions as the heater that is being installed. The steel channels or angle iron pieces need to span and be fastened to appropriate structural members. . Cut the threaded rods to the preferred length, place them through the holes in the steel channel or angle iron and secure with washers and lock nuts or lock washers and nuts. A double nut arrangement can be used here instead of at the unit heater (a double nut can be used both places but is not necessary). . Do not install standard unit heaters above the maximum mounting height shown in Table 1 9.1 . NOTE; A pipe hanger adapter kit, shown in Figure 5.2 ls available as an accessory. One kit consists of two drilled 3/4" IPS pipe caps and two 3/8. - 16 x 1-314" capscrews to facilitate threaded pipe suspension. Two kits would be required for PDP unit sizes 350 and 400 and all BDP units except size 350 and 400, and 3 kits for BDP unit sizes 350 and 400.

Gas fired heating equipment must be vented - do not operate unvented. 2. A built-in power exhauster is provided - additional exlernal power exhausters are not required or permitted. 3. lf an existing heater is being replaced, it may be necessary to resize the venting systems. lmproperly sized venting systems can result in vent gas leakage or the formation of condensate. Refer to the National Fuel Gas Code ANSI 2223.1 (NFPA 54) or CSA 8149.1 - latest edition. Failure to follow these instructions can result in serious injury or death. 4. Under no circumstances should two sections of double wall vent pipe be joined together within one horizontal vent system due to the inability to verify complete seal of inner pipes. A WARNING INSTALLATION . VENTING Model PDP and BDP unit heaters must be vented with the proper passageway as described in these instructions to convey flue gases from the unit or the vent connector to the outside atmosphere. The venting instructions are organized in sections, based on installation type. The sections are identified as follows: (D The differences between vertical and horizontal vent systems will be identified in "Section A - General lnstructions - All Units". Section A - General lnstructions - All Units A'l . lf the unit heater being installed is replacing existing equipment and using the existing vent system from that equipment, inspect the venting system for proper size and horizontal pitch, as required in the National Fuel Gas Code, ANSI 2223.1 (NFPA 54) or CSA 8149.1 lnstallation Code - latest edition and these instructions. Determine that there is no blockage or restriction, leakage, corrosion and other deficiencies, which could cause an unsafe condition. A2. The vent pipe should be galvanized steel or other suitable corrosion resistant material. Follow the National Fuel Gas Code for minimum thickness of vent material. The minimum thickness for connectors varies depending on the pipe diameter. Do not vent unit with PVC or other forms of plastic venting material. A3. All heaters come with a vent adapter for attaching the vent pipe to the heater (see Table 6.'l). Attach the vent pipe to the adapter with 3 corrosion resistant screws. (Drill pilot holes through the vent pipe and adapter prior to screwing in place). Vent pipe must not be smaller than the connector size. A4. Limit the total equivalent vent pipe length to fall between the minimum and maximum equivalent vent lengths given in Table 6.1, making the vent system as straight as possible. The equivalent length of a 5" elbow is 6' and for a 6" elbow is 7'. A5. A minimum af 12" straight pipe is recommended from the flue outlet before turns in the vent pipe. 46. Horizontal sections of vent pipe are to be installed with a minimum downward slope from the appliance of 1/4" per foot and suspended securely from overhead structures at points not greater than 3' apart. A7. Fasten individual lengths of vent together with at least 3 corrosion resistant sheet metal screws. A8. Keep single wall vent pipe at least 6" from combustible materials. For double wall vent pipe, follow the vent pipe manufacturer's clearances to combustibles. The minimum distance from combustible materials is based on the combustlble material surface not exceeding 160'F. Clearance from the vent pipe (or the top of the unit) may be required to be greater than 6" if heat damage other than fire could result (such as material distortion or discoloration). A9. Avoid venting through unheated space when possible. When venting does pass through an unheated space or if the unit is installed in an environment that promotes condensation, insulate runs greater than 5'to minimize condensation. lnspect for leakage prior to insulating and use insulation that is noncombustible with a rating of not less than 400"F. lnstall a tee fitting at the low point of the vent system and provide a drip leg with a clean out cap as shown in Figure 8.'l .

When the vent passes through a combustible INTERIOR wall or floor, a metal thimble 4" greater than the vent diameter is necessary. lf there is 6' or more of vent pipe in the open space between the appliance and where the vent pipe passes through the wall or floor, the thimble need only be 2" greater than the diameter of the vent pipe. lf a thimble is not used, all conrbustible material must be cut away to provide 6" of clearance. Where authorities have jurisdiction, Type B vent may be used for the last section of vent pipe to maintain clearance to combustibles while passing through wall or floor. See Figure 6.1. Any material used to close the opening must be noncombustible. 411. Seal all seams and joints of un-gasketed single wall pipe with metal tape or Silastic suitable for temperatures up to 400"F. Wrap the tape 2 full turns around the vent pipe. One continuous section of double wall vent pipe may be used within the vent system to pass through the wall to the listed vent cap. Refer to instruction A12 in "Section A - General lnstructions - All Units" for attaching double wall pipe to single wall pipe. A12. The following are general instructions for double wall (Type B) terminal pipe installation. How to attach a single wall vent terminal to double wall (Type B) vent pipe: 1. Look for the "flow" arrow on the vent pipe. 2. Slide the vent terminal inside the exhaust end of the double wall vent pipe. 3. Drill 3 holes through the pipe and the vent terminal. Using 3/4" long sheet metal screws, attach the cap to the pipe. Do not over tighten. How to connect a single wall vent system to a double wall (Type B) vent pipe: 1. Slide the single wall pipe inside the inner wall of the double wall pipe. 2. Drill 3 holes through both walls of the single and double wall vent pipes. Using 3/4" sheet metal screws, attach the 2 pieces of pipe. Do not over tighten. 3. The gap between the single and double wall pipe must be sealed but it is not necessary to fill the full volume of the annular area. To seal, run a large bead of 400'F silastic around the gap. A1 3. Vent termination clearances must be maintained: Table 7.1 - Vent Termination Clearances O Do not terminate the vent directly above a gas meter or regulator. A'14. Do NOT vent this appliance into a masonry chimney' A15. Do NOT use dampers or other devices in the vent or combustion air pipes. The venting system must be exclusive to a single appliance and no other appliance is allowed to be vented into it. Precautions must be taken to prevent degradation of building materials by flue products. Single wall vent pipe must not pass through any unoccupied attic, inside wall, concealed space, or floor. Uninsulated single wall vent pipe must not be used outdoors {or venting appliances in regions where the 9g% winter design temperature is below 32'F. The vent terminal must be: A16. 417. 418. A19.

Vertical vent systems terminate vertically and must be sized in accordance with the National Fuel Gas Code, ANSI 2223.'1 (NFPA 54) - latest edition. 83. The horizontal portion of the vent run cannot exceed 75% of the vertical rise (Example: lf the vent height is 10', the horizontal portion of the vent system cannot exceed 7.5'). 84. lt is recommended to install a tee with drip leg and clean out cap as shown in Figure 8.1 . 85. The vent terminates a minimum of 5' above the vent connector on the unit. 86. All vertically vented heaters that are Category I must be connected to a vent complying with a recognized standard, with a material acceptable to the authority having jurisdiction. Venting into a masonry chimney is not permitted. Refer to the National Fuel Gas Code, ANSI 2223.1 (NFPA 54) - latest edition for instructions on common venting. 87. Use a listed vent terminal to reduce down drafts and moisture in the vent. BB. Double wall vent pipe is recommended, although single wall can be used if the requirements of the National Fuel Gas Code are followed. 89. Vertical vents must terminate a minimum horizontal and vertical distance from roof lines and adjacent walls or obstructions. These minimum distances are outlined as follows (based on National Fuel Gas Code requirements for vents with diameters less than 12"): . For double wall vent pipe and I' or greater horizontal distance to any vertical wall or similar obstruction, the vent must terminate above the roof in accordance with Figure 8.1 and Table 8.1. . For double wall vent pipe and less than 8' horizontal distance to any vertical wall or similar obstruction, the vent must terminate at least 2'above the highest point where it passes through a roof of a building and at least 2' higher than any portion of a building within a horizontal distance of 10'(see Figure 8.1). Table 8.1 - Minimum Height from Roof to Lowest Discharge Opening r Size according to expected snow depth. . For single wall vent pipe and 10' or greater horizontal distance to any portion of a building, the vent must terminate at least 2' above the highest point where it passes through a roof of a building and at least 2' higher than any portion of a building within a horizontal distance of 10'. .

This section applies to horizontally vented Category lll vent systems and is in addition to "Section A- General lnstructions - All Units". C2. Horizontal vent systems terminate horizontally (sideways). C3. Seal all seams and joints of un-gasketed single wall pipe with metal tape or Silastic suitable for temperatures up to 400'F. Wrap the tape 2 full turns around the vent pipe. For single wall vent systems, 1 continuous section of double wall vent pipe may be used within the vent system to pass through the wall to the listed vent cap. Under no circumstances should two sections of double wall vent pipe be joined together within one horizontal vent system due to the inability to verify complete seal of inner pipes. Category lll vent systems listed by a nationally recognized agency and matching the diameters specified may be used. Different brands of vent pipe materials may not be intermixed. Refer to instruction 410 in "Section A - General lnstructions - All Units" for attaching double wall pipe to single wall pipe. C4. Refer to Table 9.1 for total minimum and maximum vent lengths, making the system as straight as possible. The equivalent length of a 90' elbow is 6'for 5" diameter and 7'for 6" diameter. C5. All horizontal Category lll vents must be terminated with a listed vent cap. The cap must terminate a minimum distance beyond the exterior wall surface as shown in Figure 9.2 and Table 9.1. The vent must be supported as shown in Figure 9.1. Precautions must be taken to prevent degradation of building materials by flue products.

I6-580.1 2 1. All field gas piping must be pressure/leak tested prior to operation. Never use an open flame. Use a soap solution or eguivalent for testing. 2. Gas pressure to appliance controls must never exceed 14'W.C. (1/2 psi). 3. To reduce the opportunity for condensation, the minimum sea level input to the appliance. as indicated on the serial plate, must not be less than 5% below the rated input, or 5% below the minimum rated input of dual rated units. A waRNIilG INSTALLATION GAS CONNEGTIONS 1. lnstallation of piping must conform with local building codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI 2223.1 (NFPA 54) - Latest Edition. ln Canada, installation must be in accordance with CSA-B149.1. 2. Piping to units should conform with local and national requirements for type and volume of gas handled, and pressure drop allowed in the line. Refer to Table 10.1 to determine the cubic feet per hour (cfh) for the type of gas and size of unit to be installed. Using this cfh value and the length of pipe necessary, determine the pipe diameter from Table 10.2. Where several units are served by the same main, the total capacity, cfh and length of main must be considered. Avoid pipe sizes smaller than 112". Table 10.1 allows for a 0.3" W.C. pressure drop in the supply pressure from the building main to the unit. The inlet pressure to the unit must be 6-7' WC. for natural gas and 11-14" W.C. for propane gas. When sizing the inlet gas pipe diameter, make sure that the unit supply pressure can be met after the 0.3" W.C. has been subtracted. lf the 0.3" W.C. pressure drop is too high, refer to the Gas Engineer's Handbook for other gas pipe capacities. 3. lnstall a ground joint union with brass seat and a manual shut-off valve adjacent to the unit for emergency shut-off and easy servicing of controls, including a 1/8" NPT plugged tapping accessible for test gauge connection (see Figure '10.1). 4. Use 2 wrenches when connecting field piping to units. 5. Provide a sediment trap before each unit and in the line where low spots cannot be avoided (see Figure 1 0.1 ). 6. When pressure/leak testing, pressures above 14" W.C. (1/2 psi), close the field installed shut-off valve. disconnect the appliance and its combination gas control from the gas supply line, and plug the suppty line before testing. When testing pressures 14" W.C. (1i2 psi) or below, close the manual shut-off valve on the appliance before testing.

HIGH ALTITUDE ACCESSORY KIT HIGH ALTITUDE ACCESSORY KIT Modine's gas-fired equipment standard input ratings are ceftified by ETL. For elevations above 2,000', ANSI 2223.1 requires ratings be reduced 4 percent for each 1000'above sea level. For units in Canada, CSA requires that ratings be reduced 10 percent at elevations above 2,000'. The high altitude adjustment instructions and pressure switch kits iisted in this manual are for use with units that will be installed over 2,000' These methods and kits comply with both ANSI 2223.1 and CSA requirements. lf a unit is to be installed at higher elevations AND converted from natural gas to propane gas operation, a propane conversion kit must be used in conjunction with the pressure adjustment melhods and pressure switch kits listed herein. For the Selection and lnstallation lnstructions for propane conversion kits, please see the latest revision of Modine Manual 75-511. Manifold Pressure Adjustment The inlet pressure to the unit must be confirmed to be within acceptable limits (6-7" W.C. for natural gas and 11-14'W.C. for propane gas) before opening the shutoff valve or the combination gas valve may be damaged. Heaters for use with natural gas have gas valves factory set at 3.5" W.C. manifold pressure at7.0" W.C. inlet pressure. Units for use with propane gas are set for 10.0" W.C. manifold pressure at 14.0" W.C. inlet pressure. lnstallation above 2,000'. elevation requires adjustment of the manifold pressure as described. Derated BTU Content Gas and Manifold Pressure Calculation Some utility companies may derate the BTU content (heating value) of the gas provided at altitude to a value other than 1,050 BTUift3 for natural gas or 2,500 BTUlft3 for propane gas to allow certain heating appliances to be used with no manifold pressure adjustments. For this reason it is necessary that the supplying utility be contacted for detailed information about the gas type and BTU content (heating value) before operating any heater. Tables 1'l .1 and 11.2 show the standard derated heating values (4o/o per 1,000' of elevation in the USA and 10% between 2,001' and 4,500' elevation in Canada) of natural and propane gases at various altitudes. lf the utility is supplying gas with heating values as shown in Tables 1'1 .1 and 1'l .2, the manifold pressure should be set to 3.5" WC for natural gas and 10.0" W.C. for propane gas. NOTE: Only the high fire gas pressure need be adjusted, low fire gas pressure should remain the same. Selection of the Proper Pressure and Kit To determine the proper manifold pressure at altitude and if required, the proper combustion air pressure switch kit, the full model number of the heater, the fuel to be used, and the altitude the unit will be installed at must be known. Refer to the unit serial plate or ca(on label to obtain the necessary information about the unit. After obtaining this information, refer to the gas pressure and selection charls shown in Tables 11.'l through 11.3. The pressure charts are differentiated by elevation, fuel type, and country the product is being installed in. The selection charts are differentiated by product type, altitude and fuel type. If converting from natural gas to propane gas and operation at high altitude, both a propane conversion kit and a pressure switch kit must be used {if applicable).

A WARNING INSTALLATION ELECTRICAL CONNECTIONS 1. lnstallation of wiring must conform with local building codes, or in the absence of local codes, with the National Electric Code ANSI/NFPA 70 - Latest Edition. Unit mustbe electrically grounded in conformance to this code. ln Canada, wiring must comply with CSA C22.1, Parl 1, Electrical Code. 2. Two copies of the unit wiring diagram are provided with each unit. One is located in the electrical junction box and the other is suppled in the literature packet. Refer to this diagram for all wiring connections. 3. Make sure all multi-voltage components (motors, transformers, etc.) are wired in accordance with the power supply voltage. 4. The power supply to the unit must be protected with a fused or circuit breaker switch. 5. The power supply must be within 10 percent of the voltage rating and each phase must be balanced within 2 percent of each other. lf not, advise the utility company. 6. External electrical service connections that must be installed include: a. Supply power connection (120, 208,24O,480, or 575 volts). b. Thermostats, summerlwinter switches, or other accessory control devices that may be supplied (24 volts). NOTE: Certain units will require the use of a field step-down transformer. Refer to the serial plate to determine the unit supply voltage required. Additional information may be found in Tables 19.2 and 19.3 and in the step down transformer installation instructions. 7. Refer to Figure 18.1 for the electrical junction box locations. 8. All supply power electrical connections are made in the electrical junction box of the unit. The low volt'age (thermostat and accessory control devices) can be wired to the terminals on the electrical junction box. Refer to the wiring diagram for the terminal location of all low voltage wiring. DUCT INSTALLATION When installing the heater, always follow good duct design practices for even distribution of the air across the heat exchanger. Recommended layouts are shown in Figure 13.1. When installing blower units with ductwork the following must be done. 1. Provide uniform air distribution over the heat exchanger. Use turning vanes where required (see Figure 13.1). 2. Provide removable access panels in the ductwork on the downslream side of the unit heater. These openings should be large enough to view smoke or reflect light inside the casing to indicate leaks in the heat exchanger and to check for hot spots on exchanger due to poor air distribution or lack of sufficient air. 3. lf ductwork is connected to the rear of the unit use a tr4odine blower enclosure kit or if using a field designed enclosure maintain dimensions of the blower enclosure as shown on page 25. Figure 13.1 - Recommended Ductwork lnstallations Additional Requirements for Blower Model BDP Determining Blower Speed The drive assembly and motor on all blower units are factory assembled and adjusted for operation under average conditions of air flow and without any external static pressure. The motor sheave should be adjusted as required when the unit is to be operated at other than average air flows and/or with external static pressures. Adjustment must always be within the performance range shown on page 20 and the temperature rise range shown on the unit's rating plate. To determine the proper blower speed and motor sheave turns open, the operating conditions must be known. For example, a model BDP350 unit, operating with no external static pressure, (e.9. no ductwork, nozzles, etc.) is to deliver an air volume of 6481 cfm (cfm = cubic feet per minute). This requires the unit be supplied with a 5 hp motor, a -207 drive. and the drive sheave set at 2.5 turns open to achieve a blower speed of 960 E D l0 Do not attempt to attach ductwork of any kind to propeller models. IMPORTANT Ensure that the supply voltage to the appliance, as indicated on the serial plate, is not 5% less than the rated voltage. A CAUTION 3'i,AX, iURi'JING 12" MIN.

See "Blower Adjustments" for setting of drive pulley turns open. lf a blower unit is to be used with ductwork or nozzles, etc., the total external static pressure under which the unit is to operate, and the required air flow must be known before the unit can be properly adjusted. Any device added externally to the unit, and which the air must pass through, causes a resistance to air flow called pressure loss. lf l\4odine filters are used, the pressure loss through the filters is included in the performance data on page 20. lf tt/odine supplied discharge nozzles are used, the pressure drop of the nozzles can be found footnoted at the bottom of page 23. lf filters, nozzles or ductwork are to be used with the unit, and they are not supplied by Modine, the design engineer or installing contractor must determine the pressure loss for the externally added devices or ductwork to arrive at the total external static pressure under which the unit is to operate. Once the total static pressure and the required air flow are known, the operating speed of the blower can be determined and the correct motor sheave adjustments made. As an example, a model BDP350 is to be used with a Modine supplied blower enclosure and filters attached to ductwork by others. The unit is to move 648'! cfm of air flow against an external static pressure of 0.2" W.C, which must be added for the filter pressure drop for a total of 0.4. W.C. total pressure drop. The performance table on page 20 for a BDP350, at 6481 cfm and 0.4' WC. static pressure, shows that the unit will require a 5 hp motor using a -207 drive, and the motor sheave should be set at.5 turns open to achieve a blower speed of 1050 rpm. To lnstall "l . Remove and discard the motor tie down strap and the shipping block beneath the belt tension adjusting screw (Not used on all models.) 2. For 3 and 5 HP motors, affix sheave to the motor shaft and install motor on the motor mounting bracket. lnstall belt on blower and motor sheaves. Figure 14.1 - Blower Model 3. Adjust motor adjusting screw for a belt deflection of approximately 314" with five pounds of force applied midway between the sheaves (see Figure 14.3). Since the belt tension will decrease dramatically after an initial run-in period, it is necessary to periodically re-check the tension. Excessive tension will cause bearing wear and noise. 4. The blower bearings are lubricated for life; however, before initial unit operation the blower shaft should be lubricated at the bearings with SAE 20 oil. This will reduce initial friction and start the plastic lubricant flowing. 5. Make electrical connections as outlined in the section "Electrical Connections" on page 13. Blower Adjustments Following electrical connections, check blower rotation to assure blow-through heating. lf necessary interchange wiring to reverse blower rotation. Start fan motor and check blower sheave RPM with a hand-held or strobe-type tachometer. RPM should check out with the speeds listed in "Performance Data" shown on page 20. A single-speed motor with an adjustable motor sheave is supplied with these units. lf blower fan speed changes are required, adjust motor sheave as follows: NOTE: Do not fire unit until blower adjustment has been made or unit may cycle on limit (overheat) control. 1. Shut-off povyer before making blower speed adjustments. Refer to "Determining Blower Speed" on page 13 and to "Performance Data" on page 20 to determine proper blower RPlVl. 2. Loosen belt and remove from motor sheave. 3. Loosen set screw on outer side of adjustable motor sheave (see Figure 14.2). 4. To reduce the speed of the blower, turn outer side of motor sheave counterclockwise. 5. To increase the speed of the blower turn outer side of motor sheave clockwise. 6. Retighten motor sheave set screw, replace belt and retighten motor base. Adjust motor adjusting screw such that there is 3/4" belt deflection when pressed with 5 pounds of force midway between the blower and motor sheaves (see Figure 14.3). Since the belt tension will decrease dramatically after an initial run-in period, it is necessary to periodically re-check the tension to assure proper belt adjustment. 7. Check to make certain motor sheave and blower sheave are aligned. Re-align if necessary. 8. Re-check blower speed after ad.justment. 9. Check motor amps. Do not exceed amps shown on motor nameplate. Slow blower if necessary. 10. Check air temperature rise across unit. Check temperature rise against values shown in Performance Tables on page 20 to assure actual desired air flow is being achieved. 11. lf adjustments are required, recheck motor amps after final blower speed adjustment.

A short flame can be caused bf adirty pilot oriflce. Pilot flame condition should be observedperiodically to assure trouble-free operation. To Adjust the Pilot Flame 1. Create a call for heat from the thermostat. 2. Remove the cap from the pilot adjustment screw. For localion, see the combination gas control literature supplied with unit. 3. Adjust the pilot length by turning the screw in or out to achieve a soft steady frame 3l4" to 1" long and encompassing 318"-112" of the tip of the thermocouple or flame sensing rod (see Figure 15.1). 4. Replace the cap from the pilot adjustment screw Figure 15.1 - Correct Pilot Flame A 3/4" to 1" all legs to insure system is balanced. 18. Recheck the gas supply pressure at the field installed manual shut-off valve. The minimum inlet pressure should be 6" W.C. on natural gas and 11" WC. on propane gas. The maximum inlet pressure for either gas is 14" W.C. lf inlet pressure exceeds 14" W'C., a gas pressure regulator must be added upstream of the combination gas valve'15 ,.-/6-580.1 2 START.UP PROCEDURE Main Burner Adjustment The gas pressure regulator (integral to the combination gas control) is adjusted at the factory for average gas conditions. It is important that gas be supplied to the unit heater in accordance with the input rating on the serial plate. Actual input should be checked and necessary adjustments made after the unit heater is installed. Over-firing, a result of too high an input, reduces the life of the appliance and increases maintenance. Under no circumstances should the input exceed that shown on the serial plate. Measuring the manifold pressure is done at the outlet pressure tap of the gas valve (see Figure 1 6.1 ). To Adjust the Manifold Pressure 1. Move the field installed manual shut-off valve to the "OFF" position. 2. Remove the 1/8" pipe plug in the pipe tee or gas valve and attach a water manometer of "U" tube type which is at least 12" high. 3. illove the field installed manual gas shut-off valve to the "ON" position. 4. Create a high fire call for heat from the thermostat. 5. Determine the correct high fire manifold pressure (3.5'W.C. for natural gas, 10" W.C. for propane gas). (Pressures at 0-2,000'elevation are 3.5" W.C. for natural gas, 10" W.C. for propane gas, for elevations above 2,000' refer to the instructions in "Gas Connections - High Altitude Accessory Kit" on page 11). Adjust the main gas pressure regulator spring to achieve the proper manifold pressure (for location, see the combination gas control literature supplied with unit). 6. After adjustment, move the field installed manual shut-off valve to the "OFF" position and replace the 1/8" pipe plug. 7. After the plug is in place. move the field installed manual shut-off valve to the "ON" position and recheck pipe plugs for gas leaks with soap solution. Burner Flame Adjustment Proper operation provides a soft blue flame with a well-defined inner core. A lack of primary air will reveal soft yellow-tipped flames. Excess primary air produces short, well-defined flames with a tendency to lift off the burner ports. For both natural and propane gas, the flame may be adjusted by sliding the manifold. Also, for propane gas, the air shutters can be adjusted to control the burner flame height. The air shutters can be accessed by lowering the bottom pan of the unit heater. Natural Gas Flame Control Control of burner flames on unit heaters utilizing natural gas is achieved by resetting the manifold position to either increase or decrease primary combustion air. Prior to flame adjustment, operate unit heater for about fifteen minutes. The main burner flame can be viewed after loosening and pushing aside the gas designation disc on the back of the unit. To increase primary air, loosen the manifold mounting screws and move the manifold away from the burner until the yellow- tipped flames disappear (see Figure 16.2). To decrease primary air, move manifold closer to the burner until flames no longer lift from burner ports, but being careful not to cause yellow tipping. Retighten manifold mounting screws after adjustment. Propane Gas Flame Control An optimum flame will show a slight yellow tip. Prior to flame adjustment, operate heater for at least 15 minutes. Loosen air shutter set screws and move the air shutters away from the manifold to reduce the primary air until the yellow flame tips appear (see Figure 16.3). Then increase the primary air until yellow tips diminish and a clean blue flame with a well-defined inner cone appears. It may also be necessary to adjust the manifold position in addition to adjusting air shutters to obtain proper flame. Follow the instructions under "Natural Gas Flame Control" for adjusting the manifold.

For intermittent pilot systems, both the main burner and pilot are turned off 100% when the thermostat is satisfied. For all units, the system will attempt to light the pilot for 70 seconds. lf the pilot is not sensed, the ignition control will wait approximately 6 minutes with the combination gas control closed and no spark. After 6 minutes, the cycle will begin again. After 3 cycles, some ignition controilers lockout for approximately t hour before the cycle begins again. This will continue indefinitely until the pilot flame is sensed or power is interrupted to the system. Refer to Table 18.1 for control code descriptions. Specific descriptions of the control sequence for different control codes are listed below. 1. The thermostat calls for heat. 2. The power exhauster relay is energized, starting the power exhauster motor. Once the motor has reached full speed, the differential pressure switch closes. 3. The pilot valve opens and the ignitor sparks for 70 seconds in an attempt to light the pilot. 4. Once the pilot is lit, the flame sensor proves the pilot and stops the ignitor from sparking. 5. On single stage units, the main gas valve is opened and the main burner is lit to 100% full fire. On two stage units, the gas valve may open at either 5}o/o or 100%, depending on what the two stage thermostat is calling for. 6. The air mover starts after 30 to 90 seconds to allow the heat exchanger to warm up. 7. The unit continues to operate until the thermostat is satisfied, at which time both the main and pilot valves close 100%. 8. The air mover stops after 30 to 90 seconds to remove residual heat from the heat exchanger. 6-580.1 2 17 ---- UNIT AND CONTROL OPTIONS Figure 18.1 - Factory Mounted Option Location -IY-THOH .a) *-.-\ ,5, i!_) All units include the standard (STD) features.

A wnRNING MAINTENANCE NOTE: To check most of the possible remedies in the troubleshooting guide listed in Table 27.1, refer to the applicable sections of the manual. General Maintenance The unit and venting system must be checked once a year by a qualified service technician. All installation and service of these units must be performed by a qualified installation and service agency. Before any service, BE SURE TO TURN OFF GAS AT THE MANUAL SHUT.OFF VALVE AHEAD OF THE COMBINATION GAS CONTROL AND TURN OFF ALL ELECTRIC POWER TO THE HEATER. General Unit When providing annual maintenance for the unit heater, keep the unit free from dust, dirt, grease and foreign matter. Pay particular attention to: 1. The combustion air and exhaust vent piping. 2. The burner ports and pilot burner orifices (avoid the use of hard, sharp instruments capable of damaging surfaces for cleaning these ports). To check the burner port and pilot burner orifice, see "Burner and Pilot Assembly Removal". 3. The air shutters and main burner orifices (avoid the use of hard, sharp instruments capable of damaging surfaces for cleaning these orifices). To check the air shutters and main burner orifices, see for "tt{anifold Assembly Removal." 4. The heat exchanger. Clean tubes from the bottom with a stiff non-wire brush. 5. The heat exchanger should be checked annually for cracks and discoloration of the tubes. lf a crack is detected, the heat exchanger should be replaced before the unit is put back into service. lf the tubes are dark gray, airflow across the heat exchanger should be checked to insure that a blockage has not occurred or the blower is operating properly. Electrical Wiring The electrical wiring should be checked annually for loose connections or deteriorated insulation. Gas Piping & Controls The gas valves and piping should be checked annually for general cleanliness and tightness. The gas controls should be checked to ensure that the unit is operating properly. Propeller Assembly Check the motor for lubrication if the motor is not permanently lubricated. lnspect the fan for damage and fit on motor shaft. Clean any dust, dirt or foreign matter from the fan blades. BIower Assembly The blower assembly includes the bearings, drive sheaves and belts. Blower bearings should be checked and lubricated based on the blower manufacturer's recommendations. Bearings should also be checked for any unusual wear and replaced if needed. Drive sheaves should be checked at the same time the bearings are inspected. Check to make sure the sheaves are in alignment and are securely fastened to the blower and motor shafts. Belt tension should be rechecked shortly after the unit has been installed to check for belt stretching. After the initial start-up, monthly checks are recommended. Manifold Assembly Removal To remove the manifold: 1. Shut off gas and electric supply. 2. Lower bottom pan to expose burner and manifold (see Figure 16.2). 3. Disconnect pilot tubing and thermocouple lead (or ignition cable) at the combination gas control (and ignition control). 4. Disconnect control wires for the combination gas control. 5. Disconnect gas manifold at ground union joint. 6. Remove the 2 screws holding the manifold to the heat exchanger support. 7. Clean the orifices and adjust the air shutters as necessary. 8. Follow steps 2-6 in reverse order to install the manifold assembly. 9. Turn on the electric and gas supply. 10. Check the ground union joint for leaks with a soap solution. Tighten if necessary. Burner and Pilot Assembly Removal To remove the burner: 1. Shut off gas and electric supply. 2. Lower bottom pan to expose burner and manifold (see Figure 16.2). 3. Disconnect pilot tubing and thermocouple lead (or ignition cable) at the combination gas control (and ignition control). 4. Remove the 2 burner retaining pins holding the burner in place. The burner can then be easily lowered from the unit. 5. Examine the burner and pilot assembly for cleanliness and/or obstructions as necessary (see "General Unit" for cleaning instructions). 6. Replace the burner assembly in reverse order. ln replacing the burner, be certain that the slots at the front of the burner are located properly on their shoulder rivets and that the burner retaining pins are put back into their proper locations. 7. Reconnect the ignition cable and pilot gas supply line. 8. Turn on the electric and gas supply. 1. Service or repair of this equipment must be performed by a qualifi ed service agency. 2. Do not attempt to reuse any mechanical or electrical controllers which have been wet. Replace defective controller.
