INTRODUCTION
This book contains your installation instructions and should
be kept in a safe place. It will be a handy reference guide
to operating your fireplace after installation. For you to
realize all the advantages and use of the reliable service
that has been engineered into your TEMCO fireplace, you
must carefully follow all of the instructions contained in this
book regarding installation and operation of the fireplace.
These instructions should be read carefully in their entirety
before beginning installation of the fireplace.
ONCE THE FIREPLACE HAS BEEN INSTALLED, THE
SECTION “USING YOUR FIREPLACE”, FOUND ON
PAGE 14 OF THIS MANUAL, SHOULD BE REVIEWED IN
ITS ENTIRETY PRIOR TO OPERATING THE
FIREPLACE.
It is suggested that you wear work gloves and safety
glasses to protect your hands and eyes when installing your
fireplace.
NOTE: Authorities having jurisdiction (i.e. building
inspectors, fire marshals, etc.) should be consulted before
installation to determine the need to obtain a permit.
All models are listed for use in residential and/or
manufactured housing construction in the United States

BEFORE YOU BEGIN ...A FEW BASIC RULES
1. The instructions on the following pages were designed to
make the installation of your TEMCO fireplace as quick
as possible. It is important that they be followed. This
fireplace is to be installed only by a qualified installer.
2. Use only TEMCO manufactured components, listed
under 8" Diameter Chimney System when installing a
TEMCO fireplace. Substituting other manufacturers'
components for, or altering TEMCO parts will void
the UL listing and the TEMCO warranty.
3. Check local building codes for restrictions which may not
be contained in this manual.
4. The fireplace design permits installation and framing
adjacent to combustible materials. Do not set the
fireplace on vinyl flooring or carpets.
? COMBUSTIBLE MATERIALS MUST NOT OVERLAP
THE SURFACE OF THE BLACK FRONT FACE
PANELS. COMBUSTIBLES MAY BE INSTALLED
OVER THE SIDE NAIL FLANGES UP TO THE EDGE
OF THE FRONT FACE SURFACE.
5. ALL CHIMNEY SECTIONS, ELBOWS AND FLUE
SUPPORTS REQUIRE AN ABSOLUTE MINIMUM OF
1" AIR SPACE CLEARANCE TO ALL
COMBUSTIBLES.
6. The minimum distance from the fireplace opening to an
adjacent combustible wall is 15½". See page 6 for
alternative wall shields and required R-factors.
7. If the floor in front of the fireplace is combustible, a
protective hearth extension must be used. Raised or
floor level extensions may be constructed. On flush face
models only, a raised hearth extension may be flush with
the fireplace hearth. For a raised hearth on louvered
models, the fireplace must also be installed on a
platform.
? Minimum hearth dimensions: 36" models 16" x 52"
42" models 20" x 66"
? Since many hearth extension materials are not insulating
materials, a layer of noncombustible inorganic insulating
material must be used also. See pages 6 and 7 for Rfactor requirements.
8. Adhere to the 10' Rule of Thumb for chimney height,
(see page 9).
9. Chimney supports:
a. Flue support is required for every 35' of vertical system
height.
b. Flue support is required for every 6' of offset chimney.
c. Guy wire stabilizer is required for chimneys extending
more than 6' above roof line.
10.Only TEMCO model glass doors (see chart below) may
be installed on these fireplaces.
11.The barometric damper on the Combustion Air Kit allows
air to be drawn from above, below or behind the
fireplace; but air must never be drawn from the attic or
garage spaces. Refer to the air kit installation manual for
complete installation and use information. The AK-18 Air
Kit is designed to be installed through the floor of the
home. The inlet duct should be located below the
framing and insulated flooring materials, and
communicate wit h a free air space.
12.Check your local building code to determine if grounding
is required and what procedure should be followed.
Grounding is recommended by the manufacturer if you
live in an area of high risk due to electrical storms.
13.System specifications: See Fig. 10 through 15.
14.On louvered models, which have a factory installed
blower or fan kit, it is necessary to bring a power source
to the fireplace. See separate installation instructions.
See BL-1 blower instructions for wiring procedures.

PLANNING AHEAD
CHOOSING THE LOCATION FOR
THE FIREPLACE:
Figure 1 shows some of the many ways the fireplace may
be installed. Consider the traffic pattern in the room and
location door s and windows. A corner location may be best
where space is limited.
The fireplace weighs no more than common furniture . If the
fireplace is located near a load bearing wall, additional
supports to the foundation will not be necessary.
HEAVY FACINGS SUCH AS SOLID BRICK, STONE,
ETC., MAY REQUIRE ADDITIONAL FOUNDATION
SUPPORT.
ALTHOUGH THIS UNIT MAY BE INSTALLED ON
COMBUSTIBLE SURFACES, IT MUST NOT BE

OUTSIDE AIR KIT AND GLASS DOOR
ACCESSORIES
A fireplace needs a steady supply of air in order to draw
properly. Many houses and apartments which are well
sealed lack sufficient air for normal operation. IN SUCH
HOUSES, IT IS RECOMMENDED THAT A COMBUSTION
AIR KIT BE INSTALLED. A combus tion air kit will improve
the efficiency of any fireplace, especially if used in
conjunction with glass doors, because it allows you to use
outside air for combustion instead of heated room air.
Installing the fireplace on an outside wall will simplify the
installation of the combustion air kit and reduce the amount
of necessary duct work. Install the air kit according to the
separate installation instructions packed with it. If an air kit
is to be installed, IT MUST BE INSTALLED AT THE TIME
THE FIREPLACE IS INSTALLED, before its enclosure is
finished.
The fireplace includes an integral barometric damper. The
control lever is located on the left side behind the mesh
screen.
GAS LINE
If you plan to install a gas line, it must be installed at the
time of framing the fireplace. The gas line must be installed
in accordance with local codes. See p.12 for installation
instructions.
DRAFTS
The location for the fireplace should be away from objects
such as frequently opened doors and central heat air outlets
and inle ts that will create drafts and possibly hamper the
normal flow of air into the fire.
LOCATING THE AREA WHERE THE FLUE
PIPE WILL PASS THROUGH THE CEILING
AND THE ROOF
It is very important that you determine where the flue
(chimney) will go through the ceiling and roof. Check the
structure of yo ur home to see that the location you have
chosen will make installation as easy as possible. Using a
plumb bob, hold the string from the ceiling and drop it,
moving the string until the plumb bob is in the center of the
flue collar opening, (see figure 3). Mark the spot on the
ceiling. You may wish to drive a nail through the ceiling at
this spot. Then go into the attic and find the nail. Using the
plumb bob with the ceiling nail as the center point of the
flue, mark the center of the area on the roof through which
the flue will pass. This is to see if it is possible to cut your
opening for the flue in both the ceiling and roof without
cutting either roof rafters or ceiling joists. A location that
requires cutting the least number of joists and rafters will
simplify the installation and reduce the cost. The structural
integrity of a home's floor, walls, ceiling and roof must be
maintained. It is not recommended to cut roof trusses.
CHIMNEY OUTLET
Thought should be given to the proposed location of the
chimney outlet on the roof. Objects such as trees, adjacent
buildings or embankments that are too close to the chimney
can create air circulation problems during windy weather
that could affect the way the fireplace draws air.
After careful consideration, choose the location for your
fireplace to achieve the simplest installation for maximum
efficiency.
FIREBOX AND CHIMNEY SYSTEM
CLEARANCES
The fireplace may be placed directly on a combustible floor,
against a combustible wall at marked clearances or on a
Figure 3
raised wooden platform.
If the fireplace is to be installed on a raised platform, the
platform must be a continuous level surface.
The fireplace must be secured in place so it cannot shift
positions. The nailing flanges on the sides of the firebox
make securing the firebox to the frame quick and easy. The
nailing flanges were designed to allow the installation of
1/2" wallboard or plywood flush with the face of the
fireplace.
Only the header (see figure 4) may rest on the standoffs on
top of the firebox.
Combustible materials may not cover any part of the black
metal surrounding the firebox opening. See figure 4.
Do not install the firebox over vinyl floors or carpet.
Combustible floors in front and to the sides of the firebox
opening must be protected by a noncombustible hearth
extension as shown in figure 4.
THE CAUTIONS BELOW RELATE TO LOCATIONS ON
FIGURE 4, (letters on pictures correspond with items
below).
A. When installing the hearth extension, a protective

If a protective metal strip is used under the space between
the fireplace and hearth extension, sealing of the gap
between the fireplace and hearth extension is optional.
B. COMBUSTIBLE MATERIALS MUST NOT OVERLAP
THE SURFACE OF THE BLACK FRONT FACE

OVER THE SIDE NAIL FLANGES UP TO THE EDGE
OF THE FRONT FACE SURFACE.
Use of the Plumb Bob
metal satety strip is not required below the front
face of the fireplace and mating edge of the hearth
extension if the followi ng steps are taken:
be secured to the floor of the home to prevent shifting.
Various methods of attachment may be used including
screws, nails, or common construction adhesives.
secured, the gap between the fireplace and hearth
extension must be filled or sealed with a noncombustible grout, caulk, or sealant.
5
C. If the floor in front of the fireplace is combustible, either a
raised or floor-level protective hearth extension must be
constructed. For flush-face models only, a raised hearth
extension may be flush with the fireplace hearth. To
construct a raised hearth extension with louvered
models, the fireplace must rest on a raised platform. A
raised hearth extension must have minimum dimensions as
follows:
X Y
36" models 16" 52"
42" models 20" 66"
? and be constructed of materials with an R-factor equal to
or greater than 1.20.
? A hearth extension installed directly on the floor must be
a minimum of 16" x 52" and be constructed of materials
with an R-factor equal to or greater than .80. If
combustible materials are used to construct the hearth
extension, they must not touch the black surface of the
fireplace. The same material that is us ed to protect the
top of the hearth extension must be placed between the
combustible hearth and the black face of the fireplace.
The hearth extension must be fastened to the floor to
prevent shifting and the gap between the fireplace and
the hearth extension must be sealed with a noncombustible material (400 0 F. min) if a metal safety strip is not
used. These materials (listed below) may be used for a
wall shield as well.
D. The framing header may rest on top of the standoffs.
E. The minimum distance from the fireplace opening to an
adjacent combustible wall is 15½". The minimum
distance to an adjacent combustible wall may be reduced
to 12" when an approved wall shield is used on the wall.
The wall shield must be 40" x 40" and be constructed of
a noncombustible, inorganic material having a thermal
resistance of R = 1.49.
Figure 4
Determining the R-Values
The hearth extension must be constructed of noncombustible materials which have a total thermal resistance
(R factor) equal to or greater than .80 for floor level hearth
extensions or 1.20 for raised hearth extensions and be a
minimum size as shown in the table on page 5. Choose the
desired materials and obtain the K value at 75° mean
temperature. The C value and the R value may be
calculated with the following formulas:
K = Thermal conductivity. K = BTUs-ins./hrs.-ft.2-0F
T = thickness C= Thermal conductance
R = Thermal resistance K/T = C; 1/C = R
Example: 3/4" Marble with 3/8" Micore
Determine the R value for each material used as follows:
Marble:K/T= 11/.75=14.66.
1/C = 1/14.66 = 0.068 (R factor)
Micore 300: K/T = .458/.375 = 1.22.
1/C = 1/1.22=0.82 (R factor)
After the R value is obtained on each material in this hearth,
add the R values to obtain total thermal resistance (R).
Total R factor = 0.068 + 0.82=0.89
The total must be equal to or greater than specified above.
Typical materials: Micore 300 has a K of .458; Micore 230 has a
K of .43; Micore 180 has a K of .34; Ceraboard has a K of .34;
common brick has a K of 5; cement mortar has a K of 5; marble
has a K of 11; limestone has a K of 6.5; tile has a K of 12; slate
has a K of 21; Wonder Board has a K value of 3.2.
