GAS CONNECTIONS
All gas supply connections and any pipe joint compound must be resistant to the action of liquefied
petroleum gases.
The gas inlet is located at the lower left rear.
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
1
/2" (12.7mm) iron pipe. If using the optional quick-
disconnect flex hose,
3
/4" (19mm) iron pipe must be used unless
3
/4" (19mm) to
1
/2" (12.7mm) reducing
fittings are used. Make sure the pipes are clean and free of obstructions, dirt, and piping compound.
WARNING: 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 AND ORIFICES
The standard orifices are set at 4" W.C. (Water Column) (0.993 kPa) pressure for natural gas, and
10" W.C. (Water Column) (2.48 kPa) pressure for propane gas. A pressure regulator is supplied as
part of the gas control valve.
TESTING THE GAS SUPPLY PIPING SYSTEM
When test pressures exceed
1
/2 psig (3.45 kPa), the fryer and its individual shutoff valve must be
disconnected from the gas supply piping system.
When test pressures are
1
/2 psig (3.45 kPA) or less, the fryer must be isolated from the gas supply piping
system by closing its individual shutoff valve.
