Note: To test the gas pressure, turn off the gas supply before removing the plug from
the supply pressure test port or manifold pressure test port.
There are four ports on this fireplace. The top two are connected to the rear burner
and the bottom two are to the front burner. Manifold pressures should be checked on
both to ensure they are correct.
Verify gas pressures with the fireplace lit and on the highest setting.
Please refer to the Burner Installation Manual for gas pressure testing procedure.
Caution: The gas line should be installed by a qualified service person in accordance with
all building codes. This section is intended as a guide for qualified 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. fitting. Correct gas line diameter must be used
to assure proper operation and pressure.
•
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 flare fitting 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. #23)
2. Turn on the gas supply and check that all connections are tight and leak free.
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.
