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.

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.

3. These fireplaces must be installed with either
Security Chimneys model FTF8 (8" [203mm]
inside diameter) or FTF10 (10" [250mm] inside
diameter) Chimney System only. These sys-
tems 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 artificial
wax based logs, chemical chimney cleaners or
flame colorants in your fireplace.

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 a 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 pro-
viding supplemental heat to the room.

12. Always ensure an that 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 op-
tional 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.

WARNING: THIS FIREPLACE HAS NOT
BEEN TESTED WITH AN UNVENTED GAS
LOG SET.  TO REDUCE RISK OF FIRE OR
INJURY, DO NOT INSTALL AN UNVENTED
GAS LOG SET INTO THIS FIREPLACE.

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 un-
usual environmental factors or conditions be-
yond our control.

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

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