• Gas supply line access holes are located beneath the fireplace on the flue side 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.
• 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 flanged 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.
Check local codes for additional requirements.
1. Connect the gas supply to the gas connector (Figure 29)
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.
