Vulcan-Hart VCRH12 operation manual Propane Gas Conversion

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.
