INSTALLATION INSTRUCTIONS WHEN
INSTALLING AS A VENT FREE APPLIANCE
The installation of this appliance must conform with local codes or, in the absence of local codes with
the National Fuel Gas Code, ANSI Z223.1.
NOTE: Before the unit is connected to any gas line, check the name plate on the unit for the proper
gas type you will be using.
The appliance regulator furnished on the appliance is not intended to regulate any gas pressure above ½psig.
If using LP gas, a low pressure regulator (not furnished) must be installed in the gas line between the tank
and appliance. Do not connect the appliance to the gas line if this regulator is not in place. If using natural
gas, check with the gas company to insure that proper gas pressure is available.
WARNING: An explosion could occur if a connection is made directly to an unregulated LP gas tank.
GAS
PRESSURE: Minimum inlet gas supply pressure must be 5.0” WC for natural gas or 11” WC for
LP gas for the purpose of input adjustment. Maximum inlet gas supply pressure must not exceed 10.5”
WC for natural gas, or 14” WC for LP gas. The gas line supplying the appliance must be sufficient size
to furnish the appropriate supply pressure to the appliance when being operated on the high setting.
+ The appliance and its individual shutoff valve must be disconnected from the gas supply
piping system during any pressure testing of that system at test pressures in excess of ½
psig (3.5kPa).
+ 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 ½psig (3.5kPa).
+ Always keep appliance area clear and free from combustible materials, gasoline and other
flammable vapors and liquids.
+ Pressure tap screws must be closed before turning on gas to appliance.
+ Any outside air ducts and/or ash dumps in the fireplace shall be permanently closed at the
time of the appliance installation.
+ Special provisions should be made if the unit is to be installed into a sunken fireplace by
raising the floor of the fireplace using non-combustible materials to ensure adequate
airflow.
