The supply pressure (upstream of the regulator) should be 7-9” W.C. for natural gas and 11-12” W.C. for
propane gas. At no time should the griddle be connected to supply pressure greater than ½ psig (3.45 kPa) or
14” W.C.
PROPANE GAS CONVERSION
This griddle is shipped from the factory equipped with fixed burner and pilot orifices for natural gas operation.
