IMPORTANT: PLEASE READ AND
UNDERSTAND THESE RULES TO
FOLLOW FOR SAFETY.

1. Before starting your fireplace installation,

read these installation instructions carefully to
be sure you understand them completely and in
entirety. Failure to follow them could cause a
fireplace malfunction resulting in serious injury
and/or property damage.

2. Always check your local building codes. The
installation must comply with all local, regional,
state and national codes and regulations.

3. This fireplace must be installed with Secu­rity Chimneys FTF10 [10" (250 mm) inside
diameter] Chimney System only. These sys­tems are intended for use in any application
where a traditional masonry type fireplace
would apply. The chimney system must al­ways vent to the outside of the building.

4. To ensure a safe fireplace system and to
prevent the build-up of soot and creosote, inspect
and clean the fireplace and chimney prior to use
and periodically during the heating season.

5. Use solid fuel only. DO NOT use chemical
chimney cleaners or flame colorants in your
fireplace.

Never burn treated construction lumber or
scraps. These woods burn excessively hot
and may contain chemicals used to treat
insects and fungus. When burned, these
chemicals can pose a significant hazard.

6. DO NOT use charcoal or coal under any

circumstances.

7. NEVER use gasoline, gasoline-type lantern
fuel, kerosene, charcoal lighter fluid, or similar
liquids to start or “freshen up” a fire in this
fireplace. Keep any flammable liquids at safe
distance from the fireplace.

8. NEVER leave children unattended when
there is a fire burning in the fireplace.

9. Always keep flue damper open when heat is
present in the fireplace.

10. Before servicing, allow the fireplace to
cool. Always shut off any electricity or gas to
the fireplace while working on it. This will
prevent any possible electrical shock or burns.

11. This fireplace is not intended to heat an entire
home or be used as a primary heat source. It is
designed to ensure homeowner comfort by pro­viding supplemental heat to the room.

12. Always ensure that an adequate supply of
replacement combustion air from the outside
of the house is accessible to the fire to support
normal combustion. Fireplaces consume large
volumes of air during the normal combustion
process. In the event the home is tightly sealed
with modern energy efficient features, the op­tional combustion air kit may not provide all the
air required to support combustion.

The manufacturer is not responsible for any
smoking or related problems that may result
from the lack of adequate combustion air. It is
the responsibility of the builder/contractor to
ensure that adequate combustion air has been
provided for the fireplace.

13. DO NOT use a fireplace insert or any other
products not specified herein by the manufac­turer for use with this fireplace. All gas log sets
must be operated with the damper clamped
open, including unlisted “vent free” log sets.
Listed “vent-free” log sets may be operated
with the damper closed.

14. "Smoke free” operation is not warranteed
nor are we responsible for inadequate system
draft caused by mechanical systems, general
construction conditions, inadequate chimney
heights, adverse wind conditions and/or un­usual environmental factors or conditions be­yond our control.

15. Never, under any circumstances, install a
fireplace, chimney component or any acces­sories, that has visible or suspected physical
damage as a result of handling or transporta­tion. These items should be inspected by your
distributor or qualified factory representative
to ensure safe condition. When in doubt, con­sult your distributor.

16. For additional safety considerations and
complete operating instructions, refer to the
Care and Operation Manual provided with the
fireplace.

PRECAUTIONS

Note: These fireplace systems are not difficult

to install. However, in the interest of safety, it
is recommended that the installer be a quali­fied or certified “tradesman” familiar with com­monly accepted fireplace installation and safety
techniques as well as prevailing local codes.

The most important areas of concern dealing
with the installation of factory-built fireplaces
are clearances to combustible materials, proper
assembly of component parts, height of the
chimney system, the proper use of accesso­ries supplied by the manufacturer and the
techniques employed in using finishing mate­rials applied to the wall surrounding the fire­place, hearth extensions and wall shields. Each
of these topics will be covered in thorough
detail throughout this manual. Please give
each your special attention as you progress
with your installation.

IMPORTANT: WHEN INSTALLING IN CANADA,
THE CHIMNEY AIR KIT MUST BE INSTALLED
PER THE WARNOCK HERSEY INC. LISTING.

IMPORTANT: THE MINIMUM AIR SPACE TO
COMBUSTIBLES FOR THE CHIMNEY SYSTEM
IS 2" (51 MM).

TYPICAL INSTALLATION

INTRODUCTION
General Information

This fireplace is a conventional radiant heat
fireplace with standard bar grates, optional
outside combustion air kits and optional deco­rative glass doors.

Note: Illustrations shown reflect “typical” instal­lations with nominal dimensions and are for
design and framing reference only. Actual instal­lations may vary due to individual design prefer­ences. However, always maintain minimum clear­ances to combustible materials and do not vio­late any specific installation requirements.

The TM-4500 Series fireplaces have been tested
and listed by Warnock Hersey Inc. (Report No.
J20054576-231) to U.L. 127 standard for U.S.
installations and U.L.C. S610 standard for Cana­dian installations. These units are intended for
installation in residential homes and buildings of
conventional construction, not in mobile homes.

These fireplace systems are designed for in­stallation in accordance with the National Fire
Protection Standard for chimneys, fireplaces
and solid fuel burning appliances; NFPA 211
and in accordance with codes such as the BOCA
Basic/National Codes, the Standard Mechani­cal Code, Uniform Building Codes and/or the
Canadian National Code.

Chase Enclosure

A chase is a vertical box-like structure con­structed to surround the fireplace and chimney.
Refer to

Figure 2

for a typical chase configura­tion. As with all chimney installations, avoid
overhead obstructions such as trees, power
lines, etc. A chase should be constructed and
insulated just like any outside wall. In a cold
climate, we recommend the base of the chase
should also be insulated between the solid
continuous floor beneath the fireplace and the
chase bottom. Chase insulation in a cold cli­mate installation is not required for safety.

ASSEMBLY OUTLINE
Before You Start

Check your inventory list to be sure you have all
the necessary parts supplied in good usable
condition. Check also for any concealed damage.

Check the operation of the damper. The damper
is controlled through the use of a control lever
located within the firebox opening at the top
center just behind the firebox lintel (
The control lever snaps into place at the ex­treme range of motion, up and back in the
closed position. When pulled forward and
down, the damper is open.

LOCATION OF FIREPLACE

Carefully select the proper location for heat
circulation, aesthetics, chimney obstructions
and clearance to side wall(s). With proper pre­planning, a slight adjustment of a few inches
can save considerable time and expense later
during construction and assembly.

Carefully consider the position of the fireplace
opening with respect to the location of adja­cent or nearby stairwells, bath or kitchen ex­haust fans and/or return air registers for forced
air furnaces/air conditioners that could cause
a smoking fireplace condition if the house is
tightly insulated.

When locating the fireplace, consideration must
be given to combustibles and final finishing.

ASSEMBLY STEPS

Note: The following steps represent the normal

sequence of installation. Each installation is
unique, however, and might require a different
sequence.

1. Position firebox prior to framing or into
prepared framing.

2. Install chimney air kit (Canada only).

Be sure fireplace rests on a solid continuous
floor or platform with appropriate framing for
support and so that no cold air can enter the
room from under the fireplace.

The fireplace may be positioned and then the
framing built around it, or the framing may be
constructed and the fireplace positioned into
the opening.

Usually, no special floor support is needed for
the fireplace, however, to be certain:

1. Estimate the total weight of the fireplace
system including chimney and surround ma­terials such as brick, stone, etc., to be in­stalled. Shipping weights for the fireplace may
be found on page 17.

2. Measure the square footage of the floor
space to be occupied by the system, surrounds
and hearth extensions.

3. Note the floor construction, i.e. 2 x 6’s, 2 x 8’s
or 2 x 10’s, single or double joists, type and
thickness of floor boards.

4. Use this information and consult your local
building code to determine if you need addi­tional support.

INSTALLING THE FIREPLACE

Step 1. Slide the fireplace into prepared fram-

ing or position fireplace in its final position and
frame later.

Step 2. Insert the metal safety strips, packaged
with the fireplace, beneath the fireplace as
illustrated (

Figures 6 and 7

should overlap 1" (25 mm) for continual cover­age of the floor.

Note: Safety strips are not required when fire­place rests on a noncombustible surface.

5. Plumb gas line if a decorative gas appliance

will be used. (Gas connections should only be
performed by an experienced, licensed/certi­fied tradesman.)

6. Complete the installation, finish wall mate­rial, surround and hearth extension to your
individual taste.

7. Assemble and attach optional glass door
assembly.

) to get a general idea of each element of

Fig-

your fireplace system.

PRE-INSTALLATION NOTES

The fireplace may be installed directly on a
combustible floor or raised on a platform of an
appropriate height. Do not place fireplace on
carpeting, vinyl or other soft floor coverings. It
may, however, be placed on flat wood, ply­wood, particle board or other hard surfaces.

CAUTION: DO NOT BLOCK THE HEAT-CIRCU­LATING AIR INLET AND OUTLET PORTS ON
CIRCULATING MODELS. DOING SO MAY RE­SULT IN A POTENTIAL FIRE HAZARD.

If you plan to raise the fireplace and hearth
extension, build the platform assembly then
position fireplace and hearth extension on top.
Secure the platform to the floor to prevent
possible shifting.

CLEARANCES

Minimum clearance to combustibles for the
Colonial fireplace is as follows; sides and back
– 1" (25.4 mm), combustible floor – 0" (0 mm),
adjacent wall 18" (457 mm), adjacent shielded
wall (

K factor of .84 or less 24" W x 36" H

(305 mm), ceiling – 37 ¹⁄₂" (953 mm).

Note: Clearance at the nailing flange for both
fireplace models is 0" (0mm).

Note: Adjacent wall considerations are for an
adjacent wall on only a single side. Walls
should not be placed at minimum distance at
both sides of the fireplace.
