Gas Conversion

Conversions must be performed by a Henny Penny authorized service technician.

Gas model fryers are factory available for either natural gas or propane gas. Factory conversion kits for natural gas and propane gas are available that require burner jets, pilot jet, and regulator assembly to be changed, see for kit identification.

Service Hints

On natural gas installation, the gas pressure regulator on the automatic gas control valve is factory set to 3.5 inch water column.

On propane gas installation, the gas pressure regulator on the automatic gas control valve is factory set to 10.0 inch water column.

After converting the fryer, turn on the gas supply and check for leaks. A simple method is to brush all connectors with soapy water, and watch for bubbles which indicate escaping gas.

Fire or Explosion Risk To avoid personal injury and/or property damage, do not use lighted match or open flame to text for gas leaks.

Disconnect the main circuit breakers at the circuit breaker box or unplug service cord from wall receptacle. Turn off the main gas supply to the fryer and disconnect and cap the main supply line to fryer, or possible explosion could result.
