GRDF / GRCF SERIES GAS FRYERS
GAS CONNECTION
All gas supply connections and any pipe joint compound must be resistant to the action of propane gases.
The gas inlet is located on the lower rear of the fryer. Codes require that a gas shutoff valve be installed in the gas line ahead of the fryer.
The gas supply line must be at least the equivalent of ½” (12.7 mm) iron pipe for single units and
Make sure the pipes are clean and free of obstructions, dirt, and piping compound. A battery requires one or two connections of appropriate size for the gas requirement.
Prior to lighting, check all joints in the gas supply line for leaks. Use soap and water solution. Do not use an open flame.
After piping has been checked for leaks, fully purge gas pipes to remove air.
GAS PRESSURES (ALL MODELS):
The gas pressure should be set at 4” W.C. (Water Column) (0.8 kPa) for natural gas and 10” W.C. (2.75 kPa) for propane gas. If incoming pressure exceeds ½ PSI (3.45 kPa), an additional pressure regulator must be installed.
TESTING THE GAS SUPPLY PIPING SYSTEM:
When test pressures exceed ½ PSI (3.45 kPa), the fryer and its individual shutoff valve must be disconnected from the gas supply piping system.
When test pressures are ½ PSI (3.45 kPa) or less, the fryer must be isolated from the gas supply piping system by closing its individual shutoff valve.
Fryers with Casters:
Separate instructions for installing casters are included with the casters:
The installation shall be made with a connector that complies with the
Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 or Connectors for Moveable Gas Appliances,
