Re: Tess 136 Fireplace
*
Dear Hr. Hoore:
This is to confirm that the Tess Hodel 136 fireplace has been
successfully evaluated by Warnock Hersey to UL 127, standard for.
factorv Built FireQlaces. The fireplace vas successfully tested
at a clearance af 2- .from the masonry facinQ tn a Dlyvnnrl
enclosure.
The modular blocks used to construct the interior firebox, smoke
dome and chimney transition consist of a proprietary calcium..
aluminate cement/expanded shale aggregate concrete mixture. T~e
block provides fire performance and insulating qualities
equivalent or superior to standard refractory brick.
Evidence that a specific fireplace is certified by Warnock
Hersey, is via the Warnock Hersey registered certification mark
attached to the fireplace (located on lintel).

This guide contains step-by-step instructions required to build the TESS 136 Heat-Storing Fireplace in
both new and existing houses, YOU MUST READ THESE INSTRUCTIONS BEFORE YOU BEGIN!
Should you have any questions please don't hesitate to call your local TESS dealer or our technical
sales staff in Randolph, Vermont at (802) 728-4485.

,.,-~
.;;: -I>
The TESS 136 is an all-masonry
fireplace that utilizes pre-en-
gineered modular components to
form a unique and efficient sys-
tem. It combines a Rumford-style
firechamber with a series of heat-
absorbing masonry passageways
above the fire. These two innova-
tive design features, coupled with
the use of insulating refractory
materials in the firechamber and
a chimney top damper, allow the
136 to obtain efficiencies many
times greater than a typical
masonry fireplace. In addition,
the 136 fireplace continues to
radiate heat for hours after the
fire has gone out.
The fireplace is easy to operate
but since it is a relatively new,.
idea in fireplace technology,
operating instructions are in-
cluded with each fireplace.
Please be sure to leave these in-
structions with the homeowner
after you have completed the
fireplace installation,
The 136 relies on the area around
the heat-storing components to
radiate heat into the house. For
this reason, the greatest efficien-
ilEa
TESS Fireplaces are listed by Warnock Hersey International, Inc,
(NER-QA 219) to nationally recognized safety standards. This
listing does not include accessories such as log grates or glass doors,
cies are obtained when the fire-
place is centrally located. In
some cases, space limitations will
dictate that the fireplace be posi-
tioned against an outside wall or
within an exterior chase. Since
the primary radiant heat ex-
change is through the front
facade, these locations are' also
an option if properly insulated.
However, heating efficiencies
will diminish.
This guide presents a number of
installation configurations that
can be used with either masonry
or prefabricated chimneys.
Please be sure to follow the re-
commendations for clearances
and masonry material thickness-
es around the TESS components
. and the finished fireplace as
shown in the guide. These
should be considered minimum
standards and may therefore be
increased but never reduced.
In addition, since codes vary
somewhat around the country it
is the responsibility of the
homeowner or mason/contractor
to check with all local building
inspectors for requirements per-
~-.,
(~)
...--

.....
taining to site-built masonry
fireplaces. It is the homeowner's
or mason/contractor's respon-
sibility to obtain all applicable
building permits for installation
of the TESS 136 Heat.Storing
Fireplace BEFORE construction
begins. TESS will not be held Ii.
able if the above responsibilities
are not met.
Like other site-built fireplaces,
the TES5 136 must be properly
constructed to insure optimum
performance and safe operation,
With the exception of the TESS
modular components, the 136
utilizes materials and construc-
tion techniques that are com-
monplace. The Construction
Guide offers a step-by-step
primer for assembling the 136
and, for easy reference, is divi-
ded into sections which deal with
speCific parts of the fireplace,
Please read the guide before you
begin the build, It contains im-
portant suggestions which will
save you time during the con-
struction and ensure that you
avoid potential difficulties later
on,

PLANNING THE
INSTALLATION
STEP 1 : TAKE TIME TO PLAN
THE INSTALLATION BEFORE
YOU BEGIN
The TESS 136 modular compo-
nents can generally be assem-
bled in six to eight hours by two
people. Before assembly begins,
the foundation slab and firebrick
base should be in place and com-
pletely set up. The TESS modu-
lar firechamber, containment
courses, heat storage, front com-
ponents and smoke chamber can
usually be laid-up on the first
day. Once these components
have been allowed to dry over-
night, the channel around the
heat exchanger can be poured,
the facing materials installed
around the fireplace, and the
chimney completed. Although
the TESS 136 components do not
require a mason skilled in the art
of fireplace construction for as-
sembly, familiarity with the use
of masonry tools and mortaring is
essential for a satisfactory installa-
tion.
The construction procedure for
the TESS components must re-
main the same for all installa-
tions, but the foundations, facing
material, and chimney type will
vary to fit builder and home-
owner needs and, in some cases,
to meet local codes and practices,
The following four pages show
plans and cutaway views for two
typical installations, These plans
should serve as a guide for plan-
ning your own installation.
Throughout this manual these
two typical installations are used
as the basis for describing con-
struction procedures, The darker
shaded areas represent the
prefabricated TESS and chimney
components, while the lighter
shaded areas represent locally
2
. available construction materials.
The plan in Figure 1 and the
cutaway view, Figure 2, describe
a typical installation where the
FIREPLACE is entirely INSIDE the
HOUSE, In Figures 3 and 4, the
example shows the FIREPLACE
largely OUTSIDE the HOUSE.
Although your choice of facing
materials may differ, the dimen-
sions shown in these examples
should serve as a minimum re-
quirement. In all cases, a 2" mini-
. mum air space should be allowed
from the fireplace. Wherever 4"
of masonry facing is prescribed,
this may be substituted with an
equivalent thickness of'other non-
combustible materials such as
stone or cement block covered
with tile, stucco or thin brick. In
all cases, the front facade should
be made from solid non-insulat-
ing material that will allow for
proper heat transfer through the
front of the fireplace (at least 75%
solid). DO NOT USE SPLIT FACE
BRICK OR BLOCK CONCRETE
MASONRY UNITS AS A FACING
MATERIAL FOR THETESS
~EPLACE. In some areas, split
~e brick is used as an architec-
tural surface, however, these
materials are prone to shrinking
and cracking when exposed to
heat.
Other considerations that are im-
portant in planning your fireplace
include:
1) The impact ofthe fireplace
location on traffic and air flow,
2) The height and size of the
hearth desired.
3) The size of wood storage or
other possible built-in features.
4) The impact of the fireplace
foundation on lower story spaces
(see FOUNDATIONS).
5) The impact of the fireplace
and chimney on upper floor
spaces (see FRAMING) and
structural members.
6) The type and appearance of
chimney desired. (Figures 2, 4)

The 136 consists of 18 different
masonry components which are
arranged to form various parts of
the fireplace, Each component is
marked with a letter designation
for easy reference. Figure 5
shows an exploded view of the
136 and identifies the quantity
and letter designation of each
fireplace component. Note that
there are four main groups of
components: Firechamber, Con-
tainment, Heat Exchange, and

In addition, there are a number of
installation.related accessories
which you may need to complete
the job, These are shown on the
Construction Checklist and are
available from your local TESS
dealer, (See Figures 6 and 7)
Before you start the building
process, stack the components in
like piles adjacent to the fireplace
foundation, This saves time
during the build and allows you
to check that all the pieces are at
the job site.
Please note that there are varia.
tions in the color and texture of
different components. This is be.
cause different aggregates and ceo
ments have been chosen to make
each component type,

STEP 3: BUILD THE
FOUNDATION FOR THE 136 ,
JUST AS YOU WOULD A
TRADITIONAL MASONRY
FIREPLACE FOUNDATION
In the next few pages, two typical
methods of supporting the weig~t
of the fireplace are shown.
Depending on the location of
your fireplace and grade of liind
beneath your home, one solution
will be more appropriate. In
Figures 8, 9, 10, and 11, a typi-
cal interior installation with a
raised concrete slab and a can-
tilevered hearth is shown. By can-
tilevering the hearth, the size of
the footing is reduced. This is par-
ticularly useful for saving room in
lower living spaces. A 6" slab
will best support the 16"-20"
hearth extension required for the
TESS 136,
The siie of the footings will vary
depending on the soil conditions,
The size of the foundations may
vary depending on whether addi-
tional masonry work is planned

reach above grade on the outside.
An offset in the transfer duct may
be necessary to protect combus-
tibles directly behind the fire-
chamber. Offsets or extensions
of the outside air ducting neces-
sary to reach appropriate intake
locations may be assembled
using standard 6" round gal-
vanized furnace ducting which is
generally available locally.
Follow local code requirements
when planning the footings, foun-
dations and support slabs. Addi-
tional steel reinforcement will be
necessary in seismic zones,

STEP 4: CONSTRUa
FRAMING TO ALLOW FOR
PROPER CLEARANCES
For installations on exterior walls,
the front components and chim-
ney location will require that the
ceiling be headed off at least 6"
into the room for facades that ex-
tend 4" into the room, Figure 16
shows this type of construction
and the 34" x 60" interior dimen-
sions required for an enclosure
that extends 36" beyond the inte-
rior walls.
A minimum of R-ll insulation
plus an interior sheathing of 1/2"
plywood or sheetrock is recom-
mended on the interior of any ex-
terior enclosure, This would be
added after the house is water-
tight, just prior to assembling the
TESS components and 4" masonry
facing materials.
11
Figures 11" 16, and 17 show the
minimum framing cut-outs at the
fireplace floor level for a typical
interior installation, These will
allow for the minimum pad sizes
shown (generally 52" x 56" mini-
mum), but will need to be en-
larged for masonry facings which
exceed 4" thickness, Threaded
rods installed with the fireplace
pad will provide for the best tran-
sition from foundations when
bolted to framing.
In the following examples clear-
ances to framing at the floor level
are minimized. Whenever a
raised hearth is constructed, most
jurisdictions will allow framing
which is flush, and can even be
bolted, to the masonry base.
However, in some cases, when
flush hearths are desired, local
codes may require 2"-4" airspace
clearance to framing at the hearth
level of the fireplace.
In Figures 10,16 and 17, the im-
pact of a TESS 136-5 (5 courses of
heat storage) on framing at an
eight foot ceiling is described.
For interior installations, a mini-
mum 32" x 44" cut-out is neces-
sary. If a raised hearth or addi-
tional heat storage is used, this
profile should be adjusted accord-'
ingly, always maintaining the 2"
minimum air space around the
unit. Note that extensions of
masonry veneer beyond the body
of the fireplace can be used to
span lhis 2" air space as shown in
Figures 16, 17, 57 and 59.
If a masonry exterior is desired,
the interior framing would be the
same and an additional insulated
masonry veneer would substitute
for the exterior frame walls.

THE FIRECHAMBER .
STEP 5: AFTER THE
FOUNDATION HAS CURED,
LAY 32" x 56" FIREBRICK
BASE ON THE SUPPORT SLAB
Once the suppon has been built,
the framing completed and the
roof is intact, the TESS 136 can
be assembled beginning with the
firebrick base. A watenight con-
struction area is advised, so that
the refractory components and
the refractory cement do not be-
come wet. The refractory cement
is water soluble and will not cure'
properly in damp or wet condi-
tions,
The firebrick base serves as a
foundation for both the TESS 136
components and the masonry
facade. It should be set so that
the floor of the firechamber is
flush or slightly recessed from the
finished heanh so as to retain
ashes, The base should also be
level from side to side and from
front to back.
Before laying the bricks in a mor-
tar bed, a trial layout should be
done, cutting the bricks to the
desired pattern. Figures 18 and
19 show sample patterns and the
relative future positioning of the
TESS 136 on these patterns.
These patterns are based on a 4-
1/2" x 9" x 2-1/2" firebrick and
maximum 1/4" refractory monar
joints, and are arranged to mini-
mize the number of cuts. . Note
that Figure 19 does not provide a
base for a 4" facade. For fire-
places with raised heanhs and
fully exposed facades this smaller
28" x 48" layout may be neces-
sary to allow the facade to extend
to the floor. Firebricks within the
firechamber may also be dry set
over the bed of monaro The TESS
outside air/ash dump frame is 4-
1/2" x 9" and takes the place of
one firebrick

STEP 6: AFTER THE BASE HAS
HAD SUFFICIENT TIME TO .
SET UP, BEGIN BY DRY
FITTING THE FIRST COURSE
OF FIRECHAMBER
COMPONENTS
Figure 20 shows the position of
the first course components (com-
ponents marked "A"). The base
should be square and the
fireplace opening set at 36-1/4".
As shown in Figure-21,mark the'
position of the components on
the hearth with a pencil and
remove them. At this time it is a
good idea to cover the hearth
with paper or. cardboard (as
shown in Figure 22) to avoid
staining the firebrick with mortar
during the build.
For installations in exterior or
enclosed chases, where there
would not be access to the sides
and rear of the TESS 136 during
construdion, a masonry or ce-
ment block (eMU) "casing"
should be considered at this time.
This 4" casing should be con-
strUded and '~ied" to the 136
with brick ties either by: 1) build-
ing the casing first, or 2) laying
the casing simultaneously with
the 136 components. Figure 49
shows how this casing should be
constructed,
If a gas log or gas loglighter is
desirable, the gas line for the unit
should be cut at the appropriate
location in one of the first course
TESS components (as would be
the case with other masonry
fireplaces). Please follow gas
appliance manufadurer's instruc-
tion when installing, operating
and maintaining the gas appli-
ance,
15
.----
STEP 7: ASSEMBLE
FIRECHAMBER
COMPONENTS WITH
REFRAOORY CEMENT
Apply a 1/8" to 3/16" refractory
mortar bed to the firebrick base
where the first course is marked;
then set and level the first "A"
component.
Butter the wide vertical edge of
another "A" component and set it
into place adjacent to the first
piece. Note that all refractory
mortar joints should be kept a
minimum of 1/8" and a maximum
of 3/16".
Complete the first course of "A"
components but do not put refrac-
tory mortar in the vertical joint at
the center of the firechamber as
shown in Figure 25. This joint
acts as an expansion point and
relieves any possible stress when
the walls heat up and cool down.
Apply mortar to the top of the first
course and place brick ties at
each vertical joint as shown in
Figure 26.
Brick ties should also be placed
one each at the front and at 16"
intervals around the sides and
rear every other course to tie to
the facade later. Alternatively,
brick ties may be placed in the
dovetail grooves at a later time.
Lay the next three courses of "A"
components in the same manner
as the first course. Take care to
level and plumb each course.
The next two courses consist of
three sizes of components with
angled faces and a 3 foot lintel.
These courses serve to taper the
firechamber back and side walls.

THE REST OF THE FIREPLACE,
POUR CONCRETE INTO THE
VERTICAL CHANNELS
LOCATED AT EACH VERTICAL
SEAM
The pour channels serve to lock
the firechamber components
together and care should there-
fore be taken to make sure that
they are filled without voids. The
concrete should be made with
portland Cement, sand and 3/8"
stone or gravel, or pre-mixed mor-
tar or concrete mix. The mix
should pour easily, so that it fills'
the void, but not so wet that it
leaks out of the unmortared cen-
ter joint. DO NOT TRY TO
FORCE THE CONCRETE INTO
THE POUR CHANNELS AS THIS
MAY SPREAD THE FIRECHAM-
BER WALLS.

THE CONTAINMENT
SECTION
STEP 9: ASSEMBLE THE
CONTAINMENT
COMPONENTS ON THE
FIRECHAMBER
The containment section consists
of 7 courses of "W" and "X" com.
ponents.
A standard Type S mortar mix
and 3/8" mortar joints should be
used on this section of the 136.
Continue to use two brick ties at
each of the lhree vertical joints,
on each course and additional
ties for the facade where neces-
sary.
In order for the front wall spacers
to fit properly between the con-
tainment components, the dis-
tance across the inside of the
finished enclosure must be a mini-
mum of 39-1/4", In addition to
checking level and plumb, check
to see that the fireplace is not
twisting as it rises above the
firechamber. (Figure 36)
Build the containment section up
to a point where it is difficult to
set additional components in
place, then set and level the
precast lintel.
The lintel should be positioned so
that it is even with the top of the
course on which it rests. Re-frac-
tory mortar should be used ex-
cept forthe end faces of the lin-
tel. This will allow for expansion
during firing, Stuff the area be-
tween the end of the lintel and
..
th.chamber components with
fiberglass insulatiory.t? allow for .
expansion. .> ..,::...~:::~

The next course should be set so
that the small holes are facing
do~n and the sloped portion of
the smoke passageway is facing
toward the front of the fireplace,
The small holes of the first course
should "mate" with the small

The third course should be set
with the large holes facing down
and the sloped portion of the
smoke passageway facing toward
the rear of the fireplace, leaving
the small holes facing up at the

,
The first smoke chamber course,
consisting of "0" and "T" com-

the heat exchange units using
refractory mortar. As was done in
the firechamber section, keep the
refractory mortar joints in the
smoke chamber between 1/8"
and 3/16". Take care not to
obstruct the passageways of the
heat exchange section. Be sure
that the "I" components are
placed so that they taper to a
smaller opening.

using the two "U" components, If
a clean-out or access port is
desired, it should be installed at
this point, perhaps in place of
7" x 7" spacers. For offset fl ues,
this could also give future access
to rethreading cable guides, if
. necessary

I n most cases it wi II be riecessary
to let the mortar on the com-

before pouring concrete in the
void. In this way there will be no .
danger of these components be-
coming dislodged during the pour.
Use the same concrete mix as
was used to fi II the pour chan-
nels. It will take approximately 2
cubic feet of concrete per vertical
foot of heat exchange to fill this
area.

CHAMBER IS COMPLETE
Chimney and Top Damper
Once the TESS modular com-
ponents are installed, the chim-
ney and facing materials can be
added. The TESS 136 can be
operated with either of two types
of chimney:
1) A 10" interior diameter Class
"A" insulated factory-built chim-
ney (see Figure 3).
2) A nominal 12"x12" masonry
chimney with a minimum interior
flue liner size of 11 "xlI ", stand-
ard 1/2" to 1" air space around
the liner, and 4" nominal mason-
ry wall thickness (see Figure 2).
If an offset is required to clear
framing, these components
should be installed now (see
OFFSETS AND STACKING).
If the factory-built chimney op-
tion is chosen, it may be install-
ed before the facing. However,
if a masonry chimney is to be in-
stalled it must be built after the
facing and smoke chamber
casing are installed since the'
masonry chimney will rest on the
facing materials,
The factory-built chimney installa-
tion requires the use of a masonry
anchor plate installed on top of
the last smoke chamber course.
21
, '
The factory-built chimney system
should include components listed
for this type of application.
Generally, a bead of refractory
mortar or fibered stove gasket ce-
ment is applied to the top section
and the anchor plate is secured
by screws and lead anchors. .
Anchor plates must be a mini-
mum of 15"x 15" to adequately'
cover the smoke chamber open-
ing,
Follow the manufadurer's instal-
lation instructions for the installa-
tion of all factory-built chimney
components. It is recommended
that all exterior chimney com-
ponents be enclosed in a chase to
maintain the minimum flue gas
temperatures required for proper
drafting.
The TESS 136 with five courses of
heat storage requires a minimum
of 8' 8" of chimney height (17'6"
height from hearth to top of chim-
ney for 136-5; 20' for 136-7),
without offsets, and the seven
course fireplace requires 10 feet.
If offsets are used, this minimum
height will increase (see OFF-
SETS).
The masonry chimney should be
constructed according to stand-
ards required by local codes and
the minimum requirements stated
here. Take care not to drop ex-
cess mortar into the heat-storing
components during construction,
The cable which operates the top
damper must be installed in the
fireplace after the TESS com-
ponents have been mortared in
place and before the chimney
has been built. The cable is then
passed through the Ii ner of the
chimney as it is constructed (alter-
natively a rope may be used
during the build in place of the
cable and then used to thread the

". ,;:.
.we place after the chimney has
IWn constructed).
P<a'ts conduct the primary heat
ex~nge, the masonry jacket
there should never be thicker
than on the sides and rear. Only
solid masonry units (at least 75%
solid) should be used since the air
spaces in hollow units would in-
sulate and inhibit the heat trans-
fer.

.
Install the chimney-top damper
and adjust the damper cable ac-
cording to the instructions in-
cluded with the damper. If a fac-
tory-built chimney is used, the
top damper is installed just below
the cap on the interior of the last
chimney section.
Any stone, brick or solid cement
product facing may be used along
with a tile, plaster or painted sur-
face. However, different facing
materials have varying degrees of
thermal conductivity and differ-
ent heat-storing capability. The
type and thickness of facing
materials should be a factor in
planning the installation. For ex-

mum on the rear and sides for un- .

For simplicity, these illustrations
show the masonry facing inde-
pendent of the TESS unit.
The masonry facing should be
"tied" to the TESS components
using brick ties placed every 16"
vertically and horizontally on all
sides. These ties can be mortared
into the dovetail keyways pro-
vided on the TESS components or
placed in joints between courses.
The front facing materials should
also be mortared solid to the TESS
front components as shown in
Figure 52, This will insure the
best condudivity for heat ex-
change. When the masonry
facade overlaps the 2" air space
on an enclosed fireplace, it may
be useful to ventilate this space
by leaving vertical mortar joints
open at the top and bottom of the
facade in front of this space.
Before construding the masonry
facing, the fireplace opening
should be planned so as to ac-
commodate glass doors after in-
stallation, The speCifications for
these openings are shown in
Figures 50 and 51 for arched or
rectangular TESS doors. These
opening specifications should
also be respeded so as to main-
tain the correct opening size for
proper combustion and drafting.

NOTE: For installations where
an uneven facing material
(fieldstone, etc.l is used, the open-
ing should not be made to the
maximum dimensions listed in
Figures 50 and 51 as this may
produce gaps between the outer
door frame and the facing.
It is also recommended that the
doors be on hand when the front
facing is being applied. This way
the mason can ensuI.~ a proper fit
by constructing the opening to fit
the door being installed
Although the bricks used in these.
drawings are 3-1/2" x 7-5/8" x 2-
5/8", brick sizes vary tremendous-
ly, and the exact layout would
vary as well,
During construction of the
fireplace opening, brick ties
should be installed above the lin-
tels to support an insulation
board facing shield on the interior
of the fireplace opening. Figures
53 through 56 show the installa-
tion of these clips and the posi-
tion of insulating board for both
arched and rectangular openings,
This is recommended to protect
the mortared facing from the high
temperatures inside the firecham- .
ber just below the precast TESS -.
lintel.
After the facing is complete and
support clips are installed, cut a
cardboard template for the area
inside and above the facing lintel
as shown in Figures 54 and 56,
The fibered insulation board can
then be cut to this shape and
secured in place by applying
refractory cement to the back of
the shield, sening the shield in
place, and then folding the sup-
port clips against the board.

After the masonry facing has
reached the top of the contain-
ment and while there is still physi-
cal access to the smoke chamber
area, a 6" cement block (eMU) or
other masonry casing should be
mortared in place over the transi-

fireplace facing (or smoke cham-
ber casing) and combustibles. In
Figures 57, 58 and 59, this 2" air
space is apparent on the sides,
front and back of the casing area.
On the sides and rear of the
smoke chamber area, this 2" air
space is automatically created
when the walls of the facing rise
above 90". These "extensions" of
the masonry facing, just as the ex-
tensions on the sides of the

combustibles once they extend at
least 2" beyond the body of the

APPLlCA liONS
OFFSETS AND STACKING
In installations where two or
more fireplaces are adjacent or
where the placement of the
fireplace conflicts with major
framing members, the use of an
offset may be necessary, Figures
&0,61 and 62 show a typical in-
stallation where three fireplaces
are installed and where offsets
have been used,
TESS manufactures offset transi-
tion components that form a
FIGURE 59
smooth and gradual passageway
forthe flue gases. The TESS 136
offsets average 4-1/2" of horizon-
tal offset per 7-3/4" rise, or about
25 degrees of offset. These offset
components should be added
after the smoke chamber casing is
built and before the chimney in-
stallation, Additional masonry
support will be required to trans-
fer the weight of the offsets to the
containment walls.
Due to the increased friction
caused by offset flues, it may be
necessary to increase the mini-
mum chimney height (calculated
from the top of the smoke cham-
ber), This will vary depending on
.
For all of the masonry facing in
the front which extends above
85" from the floor of the fire-
chamber, the casing and facing
materials will together form a
solid 8" wall. In this case, com-
bustibles may only '~ouch" the
masonry facing at a point at least
2" from the smoke chamber
casing, The casing in the front
will be only 4" thick wherever the
facade is exposed and then
change to 6" thick when the
facade stops, In no case should
framing members rest on or be
supported by the masonry faci ng
(see Figure59),
Where the body of the fireplace,
smoke chamber or chimney pier-
ces a ceiling or roof, firestopping
should be built into place. Typi-
cally, 24 gauge galvanized sheet
metal can be mortared into the
smoke chamber casing joints and
nailed to framing, spanning the
air space around the smoke cham-
ber area.
climatic and wind conditions at
the building site.
As is apparent from Figure 60,
TESS 136 fireplaces cannot easily
be stacked directly on top of each
other unless there are very large
offsets and very high ceilings,
Some overlapping of support,
however, is frequently pOSsible as
long as additional 8" masonry sup-
port walls are installed to carry
the balance of the upstairs
fireplace weight not shared by
the lower unit. The shared sup-
port of the upper fireplace should
oe carried in the containment
walls and not by the smoke cham-
ber of the TESS Fireplace, Rein-

The foundation and footing re-
quirements for stacked fireplaces
are shown in Figures 61 and 62,
In all cases, the minimum footing
width will be 44", not including
hearth extensions. The length
will vary depending on the rela-
tive position of the upper units,
Additional steel reinforcement
and masonry or concrete struc-
ture will be necessary for seismic
areas (see SEISMIC CODES AND
REQUIREMENTS).
SEISMIC CODES AND
REQUIREMENTS
The TESS 136 is manufactured
with internal channels which are
ideally suited for seismic reinfor-
cement. In addition, the relative-
ly large size of refractory com-
ponents makes it particularly
stable in shaky conditions, The
range of seismic zones and their
consequent requirements make it
difficult, however, for a single
solution. Contact local building
officials regarding seismic zone
requirements in your area. It is
recommended that any plans be
reviewed by a certified profes- .
sional engineer to correctly
specify seismic reinforcements.
All the installation illustrations in
this manual are representative of
seismic zone "0" construction,
