WARNING: Failure to position the parts in accordance with these diagrams or failure to use only parts specifically
approved with this appliance may result in property damage or personal injury.
STEP ONE PREPARATION:
1. Verify that the Valve Assembly is correctly matched to the log set,
burner, and gas supply.
2. Turn off Fireplace Gas Supply (Figure 1A) .
3. Thoroughly clean fireplace floor of any ashes and have a qualified
chimney cleaner insure that the chimney flue and firebox are free of
soot, creosote, and loose paint.
4. Attach Damper Clamp (Figure 2A) over edge of fireplace Damper

IMPORTANT GUIDELINES
•
The chimney damper must be wide open and fixed in a manner to maintain a permanent free opening at all
times as outlined above.
•
The area of the flue must be not less than 1/10 the area of the fireplace opening.
•
This gas log set must be installed in fully
VENTED
metal or masonry fireplace with a working flue that is safe for burning a
wood fire.
•
The flue must be free of any obstructions and must exhaust all products of combustion.
•
At least 12” of noncombustible or heat resistant material is required above the fireplace. A fireplace hood will be
required to act as a heat deflector in protecting combustible fireplace surrounds (facing and/or mantel) if certain
minimum clearances cannot be met.
•
Be certain that combustible flooring material (i.e. carpet, tile etc.) is not too close to this gas appliance. If this appli-
ance is at floor level or less than 6” above the floor, there must be at least 12” of noncombustible material between
the base of the fireplace and any combustible flooring.
•
Input ratings shown in BTU per hour are for elevations up to 2,000 ft. For elevations above 2,000 ft. refer to the
National Fuel Gas Code, or visit www.nfpa.org.
•
The Gas appliance and it’s main gas valve must be disconnected from the gas supply piping system during any
pressure testing of that system as required by NFPA 54.
