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.
Verify gas pressures with the fi replace lit and on the highest setting.
Please refer to page 51 for gas pressure testing procedure.
GAS VALVE INLET
Servicing of the appliance can be performed from inside the unit and through the access
panel located in the fi rebox bottom.
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 beneath the fi replace on the fl ue side 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 61,000 BTU/HR on both Natural Gas and
Propane.
• A drip leg must be installed in the gas supply line going to the gas control
valve to minimize the possibility of any loose scale or dirt within the gas
supply line from entering the control valve.
•
It is essential that a union or fl anged connection be installed just upstream of the
valve and inside the control compartment 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. #24a).
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.
