sories, that has visible or suspected physical
damage as a result of handling or transporta-
tion. These items should be inspected by your

sult your distributor.

PRECAUTIONS
Note: These fireplace systems are not difficult
to install. However, in the interest of safety, it
is recommended that the installer be a quali-
fied or certified “tradesman” familiar with com-
monly 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 accesso-
ries supplied by the manufacturer and the
techniques employed in using finishing mate-
rials applied to the wall surrounding the fire-
place, hearth extensions and wall shields.
Each of these topics will be covered in thor-
ough detail throughout this manual. Please
give each your special attention as you progress
with your installation.
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" (254mm) inside diam-
eter] Chimney System only. This fireplace is
intended for outdoor installation only. The chim-
ney system must always vent to the outside of
the building or structure.
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 at safe
distance from the fireplace.
8. NEVER leave children unattended when
there is a fire burning in the fireplace.
9. Before servicing, allow the fireplace to cool.
Always shut off any gas to the fireplace while
working on it. This will prevent the possibility
of burns.
10. This fireplace is not a heater. It is designed
to ensure homeowner comfort by providing
supplemental heat to its immediate area.
11. Always ensure that the air inlet to the fire-
place is free from debris and any other obstruc-
tions that can block the entrance of air.
12. DO NOT use a fireplace insert or any other
products not specified herein by the manufac-
turer for use with this fireplace.
13. "Smoke free” operation is not warranteed
nor are we responsible for inadequate system
draft, general construction conditions, inad-
equate chimney heights, adverse wind condi-
tions and/or unusual environmental factors or
conditions beyond our control.
WARNING: TO AVOID THE RISK OF
DAMAGING FIREPLACE MATERIALS
AND INCREASING THE RISK OF FIRE,
DO NOT USE THE FIREPLACE TO COOK
OR WARM FOOD.
