Caution: The gas line should be installed by a qualifi ed service person in accordance with
all building codes. This section is intended as a guide for qualifi ed technicians installing this
appliance. Consult local and/or national building codes before proceeding.
• Gas supply line access holes are located at the top and left sides of the Control Box.
Gas valve inlet accepts a 3/8" N.P.T. fi tting. Correct gas line diameter must be used to
assure proper operation and pressure.
• The fi replace has an input rate of 54,900 BTU/HR on both Natural Gas and
Propane.
• NOTE: A sediment trap, as per national fuel gas code, must be installed in the
gas supply line no more than 6 feet from the gas control valve to minimize the
possibility of any loose scale or dirt within the gas supply line from entering
the control valve.
• DO NOT HARD PIPE GAS LINE TO VALVE. A method of disconnecting the valve
from the gas line such as a union or fl are fi tting must be provided to allow for repair
or replacement of the gas valve.

Check local codes for additional requirements.
1. Connect the gas supply to the valve (Fig. #26)
2. Turn on the gas supply and check that all connections are tight and leak free.
WARNING: Use EXTREME CAUTION when using soap and water to
do a leak test on the valve/fi ttings. There are electronics around
and below the valve, that can/will be damaged if they come in
contact with water.
WARNING: The access panel including gasket must be
reinstalled after conversion/installation or servicing
has been completed. Failure to do so will cause
overheating and premature failure of the control system.
