GAS CONNECTION. Make gas connection between manual shut off valve and furnace valve with
approved connectors. Compounds used on threaded joints of gas piping shall be approved for use with
L.P. gas. The gas lines must be checked for leaks by the installer with soapy water or liquid detergent,
never an open flame. If connections are not exposed, a pressure test must be run. Be sure to disconnect
the gas supply line from the appliance valve before pressure testing. The manifold pressure is pre-set at
the factory and should be 3.5” w.c. for Natural Gas and 10” w.c. for L.P. gas. The minimum inlet
pressure for Natural Gas is 4.5” w.c. and 11” w.c. for L.P. Gas, “for purpose of input adjustment”. The
maximum inlet pressure should never exceed 7.0” w.c. on Natural Gas or 14” w.c. on L.P. Gas.
