OWNER’S MANUAL

INSTALLATION

 WARNING: Before installing

in a solid fuel burning fireplace,
the chimney flue and firebox must
be cleaned of soot, creosote,
ashes and loose paint by a quali-
fied chimney cleaner. Creosote
will ignite if highly heated. A dirty
chimney flue may create and dis-
tribute soot within the house. In-
spect chimney flue for damage.

NOTICE: Installation, service, and
repair of this appliance must be
performed by a qualified installer,
service agency, company or gas
supplier experienced with this
type of gas appliance. Only fac-
tory authorized components listed
in these instructions may be used
in accordance with the
manufacturer’s instructions and
all codes and requirements of the
authority having jurisdiction. Any
modifications to this kit, or use of
unauthorized components or ac-
cessory items will void the
manufacturer’s warranty, and may
result in a hazardous condition.

CHECK GAS TYPE

natural gas, you must install ON/OFF Safety
Valve/Pilot Kit (see Accessories, page 17).
Call dealer where you bought log set.

 If the fireplace does not have a gas supply
shut-off valve, one must be installed.

 CAUTION: Do not remove

the metal data plates attached
to the burner pan. The data plates
contain important warranty in-
formation.

VENTING SPECIFICATIONS
FOR INSTALLATION

The fireplace chimney flue and vent must be
drafting properly. To check the vent for
proper drafting: Light a tightly rolled news-
paper on one end and place it at the inside
front edge of the fireplace. Observe the
smoke and be sure the vent is properly
drawing it up the chimney. If the smoke
spills out into the room, extinguish the flame
and remove any obstruction until proper
venting is achieved.

The chimney flue must remain open a mini-
mum of 3" at all times during the operation
of this log set.
