The minimum 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 hotplate be connected to
supply pressure greater than ½ psig (3.45 kPa) or 14” W.C.
PROPANE GAS CONVERSION
This hotplate is shipped from the factory equipped with fixed burner orifices for natural
gas operation. The burner orifices required to convert the hotplate to propane gas are
shipped with the hotplate in the shipping packaging. It is recommended that a trained gas
service technician with the necessary tools, instruments and skills perform the
conversion.
To convert to propane, following steps must be completed:
1. Remove all natural gas burner orifices and install the provided propane burner orifices.
2. Set the regulator to 10” W.C. by inverting the regulator spring plug. See Fig. 3.
Prior to lighting, check all joints in the gas supply line for leaks.
Use soap and water solution. Do not use an open flame.
