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.
If 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 respon-

sible for any smoking or related problems that

may result from the lack of adequate combus-

tion 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 manufac-

turer 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 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, consult

your distributor.
16. For additional safety considerations and

complete operating instructions, refer to the

Care and Operation Manual provided with the

fireplace.

unDErSTanD ThESE ruLES TO

FOLLOW FOr SaFETy.

1. Before starting 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. The Estate™ Series 36" and 42" models

may be installed with Security Chimneys™

FTF10 [10" (250mm) inside diameter] chimney

systems. The Estate Series 50" model may

only be installed with Security Chimneys™

FTF13 [13" (330mm) inside diameter] chimney

system. 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 pre-

vent 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.
