INSTALLATION
CHECK GAS TYPE
Use only natural gas. If your gas supply is not natural gas, you must
convert the appliance to propane/LP. Follow the instructions on page 7.
If the fireplace does not have a gas supply shutoff valve, one must
be installed.
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 newspaper
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 damper must be fixed open to provide a minimum
of 81 sq. in. of free air opening during operation of this log set. A
multipurpose damper clamp is provided to fix the damper in position.
The minimum flue sizes shown in Figure 2 are based on a 6'
chimney height using round pipe. Your minimum flue size will
vary based on input rate and chimney height. Refer to the National
Fuel Gas Code ANSI Z223.1/NFPA 54, Section 6.6, for details.
CAUTION: Do not remove the data plates at-
tached to the burner pan. The data plates contain
important warranty and safety information.
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 qualified
chimney cleaner. Creosote will ignite if highly heated.
A dirty chimney flue may create and distribute soot
within the house. Inspect chimney flue for damage.
NOTICE: Installation, service, and repair of this appli-
ance must be performed by a qualified installer,
service agency, company or gas supplier experi-
enced 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 having jurisdiction. Any modifications to
this kit, or use of unauthorized components or acces-
sory items will void the manufacturer’s warranty, and
may result in a hazardous condition.
