Step 4: Gas Connection
This Fryer ships from the factory configured for areas with an altitude that is lower than 2,000 feet. (If being
installed above 2,000 feet the orifices will need changed. Failure to install proper orifice size will void warranty)
3/4" Male NPT line for gas connection is located near the lower right rear corner of the fryer.
Recommended Regency 48" Gas lines: (more sizes available)
Mobile: 600GKM3448
Stationary: 600GKS3448
1. Ensure gas supply and gas type, as shown on unit serial plate agree. Unit installation must conform with the
National Fuel Gas Code, ANSI Z223.1, the National Gas Installation Code, CAN/CGA-B149.1, or the Propane
Installation Code, CAN/CGA-B149.2 as applicable and in accordance with local codes.
2. A manual gas shut-off valve must be installed in the gas supply line ahead of the appliance and gas pressure
regulator for safety and ease in servicing.
3. The gas pressure regulator supplied must be installed on the appliance prior to connecting the equipment to the
gas line. Failure to install a regulator could be potentially hazardous and will void limited equipment warranty.
4. Pipe threading compound must be resistant to the action of liquefied petroleum gases.
5. Connect the gas supply directly to the 3/4" male NPT connector located near the lower left rear corner of the
fryer. When tightening the supply pipe, be sure to hold the mating connector extending from the unit securely with
a wrench.
ALL PIPE JOINTS AND CONNECTIONS MUST BE TESTED THOROUGHLY FOR GAS LEAKS. USE
ONLY SOAPY WATER FOR TESTING ON ALL GASES. NEVER USE AN OPEN FLAME TO CHECK
FOR GAS LEAKS. ALL CONNECTIONS MUST BE CHECKED FOR LEAKS AFTER THE UNIT HAS
BEEN PUT INTO OPERATION. TEST PRESSURE SHOULD NOT EXCEED 14" W.C.
THIS APPLIANCE AND ITS INDIVIDUAL COMBINATION GAS VALVE MUST BE DISCONNECTED
FROM THE GAS SUPPLY PIPING SYSTEM DURING ANY PRESSURE TESTING OF THAT SYSTEM
AT TEST PRESSURES IN EXCESS OF 14”WC (1/2 PSIG or 3.45 kPa).
If the incoming gas pressure is in excess of 14"WC (1/2PSI, 3.45 kPa), a proper
step-down regulator will be required. See PHOTO 1 for LP application

Pressure Regulator:
A combination gas valve and pressure regulator, which is provided
with each unit, is set to maintain a 4" W.C. manifold pressure for natu-
ral gas or 10.0" W.C. manifold pressure for propane gas. However, to
maintain these conditions the pressure on the supply line, when all
units are operating simultaneously, should not drop below 7" W.C. for
natural gas or 11" W.C. for propane gas. Fluctuations of more than 25%
on natural gas or 10% on propane gas will create problems and affect
burner operating characteristics. A 1/8" tap to measure the manifold
pressure is located on the combination gas valve, which is on the
burner manifold located directly below the burners inside the cabinet.
