2.4 Connecting to the Gas Supply
GAS CONNECTIONS AND PIPE SIZES
The size of the gas supply pipe is very important. If the pipe is too small, the gas pressure at the
burner manifold will be low. This will cause slow recovery and delayed ignition. The incoming gas
supply line should be a minimum of 1½ inches (38mm) ID.
When configured for natural gas, this equipment requires a standard gas pipe size of ¾ inch (19mm)
ID for connections within 20 feet (6m) of the supply line, provided no more than 4 fittings or elbows
are used in the run. For a pipe run over 20 feet (6m), increase the pipe size to 1 inch (25.4mm). For
use with LP (Propane) gas, the next smaller pipe size may be used.
IF IN DOUBT ABOUT THE PIPE SIZE TO BE USED, CONSULT YOUR LOCAL GAS
COMPANY.
DANGER
Before connecting new pipe to this equipment, the pipe must be blown out
thoroughly to remove all foreign material. Foreign material in the burner and gas
controls may cause improper and dangerous operation.
1. Connect the equipment to the gas supply line.
When making connections, apply a small amount of Loctitite
®
PST 56765 or equivalent thread
compound to the male threads only. DO NOT apply the compound to the first two threads. This
will prevent clogging of the burner orifices and control valve.
2. Open the gas supply to the fryer and check all piping, fittings, and gas connections for leaks. A
soap and water solution should be used for this purpose.
DANGER
Never use matches, candles, or any other ignition source to check for leaks.
If gas odors are detected, shut off the gas supply to the fryer at the main shut-off
valve and contact the local gas company or an authorized service agency for service.
The rethermalizer and any shut-off valves installed between the rethermalizer and
the gas supply line must be disconnected from the gas supply line during any
pressure testing of the supply line at pressures equal to or greater than ½ PSIG
(3.45kPa, 13.84 inches W.C.).
3. Close the drain valve and fill the cookpot with water and boil-out solution to the overflow. Light
the burners and perform the boil-out procedures that are described in the “Start-Up Procedure”
and “Boiling Out the Cookpot” sections in Chapter 3 of this manual.
