7. GAS LINE CONNECTION AND TESTING
WARNING: Only persons licensed to work with gas piping can make the gas connections to this appliance.
This appliance is equipped with a 3/8” stainless steel flex line from the valve. This line may be routed through the hole in the rear
of the pedestal, or on inserts, routed through the fire box sides. An adapter plate is available for installations that do not allow flex pipe through cabinetry.
NOTE: Consult your local authorities and in CAN. the
The appliance and its shutoff valves must be disconnected from the gas supply piping system during any pressure testing where the pressure exceeds 1/2 PSIG (3.45 kPa) or damage will occur to the valve.
The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).
Always check for gas leaks with a soap and water solution or an approved manner after completing required pressure tests.
ORIFICE SIZES, PRESSURES AND BTU'S
The efficiency rating of this appliance is a product thermal efficiency rating determined under continuous operating conditions and was
determined independently of any installed system. All models are equipped with a variable output gas control.
