warranty information.
WARNING: Before installing in a solid fuel burning
fi replace, the chimney fl ue and fi rebox must be cleaned
of soot, creosote, ashes and loose paint by a qualifi ed
chimney cleaner. Creosote will ignite if highly heated.
A dirty chimney fl ue may create and distribute soot
within the house. Inspect chimney fl ue for damage. If
damaged, repair fl ue before operating heater.
NOTICE: Installation, service, and repair of this appli-
ance must be performed by a qualifi ed installer, service
agency, company or gas supplier experienced with
this type of gas appliance. Only factory authorized
components listed in these instructions may be used
in accordance with the manufacturer's instructions
and all codes and requirements of the authority hav-
ing jurisdiction. Any modifi cations to this kit, or use
of unauthorized components or accessory items will

FLUE OPENING SPECIFICATIONS
Note: This vented appliance must be installed only in a solid-fuel
burning fi replace with a working fl ue and constructed of noncom-

CHECK GAS TYPE
Use only natural gas. If your gas supply is not natural gas, you must

Call dealer where you bought log set.
If the fi replace does not have a gas supply shutoff valve, one must

The fi replace chimney fl ue and vent must be drafting properly. To
check the vent for proper drafting: Light a tightly rolled newspaper

serve the smoke and be sure the vent is properly drawing it up the
chimney. If the smoke spills out into the room, extinguish the fl ame
and remove any obstruction until proper venting is achieved.
