3. (Gas) Connect the gas supply pipe to the combination gas valve inlet (natural
or propane gas). NOTE: Larger burners have a separate gas train that you
must connect to the burner before connecting the supply pipe to the inlet.
Note: Be sure the gas supply line is of adequate size for the
firing rate of your burner and for the length of the gas pipe
supply run. Refer to the gas burner vendor manual for
information on pipe capacities versus run lengths.
Or
(Oil) Connect the fuel-oil supply tube to the fuel-oil pump inlet .
WARNING! Refer to your fuel-oil burner manual to determine
if a fuel-oil return line is required.
