Frymaster GC - Manual (Page 14)

2-7
The size of the gas line used for installation is very important. If the line is too small, the gas pressure
at the burner manifold will be low. This may cause slow recovery and delayed ignition. Frymaster
recommends the incoming gas supply line be a minimum of 1 ½” (38mm) in diameter. Refer to the
chart below for the minimum sizes of connection piping.
Gas Connection Pipe Sizes
(Minimum incoming pipe size should be 1½” (38 mm))
Gas Single Unit 2-3 Units
Natural ¾” (19 mm) 1” (25 mm)
Propane ½” (13 mm) ¾” (19 mm)
For distances of more than 20 feet (6m) and/or more than four fittings
or elbows, increase the connection by one pipe size.
Before connecting new pipe to your unit, the pipe must be thoroughly blown out to remove any
foreign particles. If these foreign particles get into the burner and controls, they will cause improper
and sometimes dangerous operation.
1. Connect the quick-disconnect hose to the cooker quick-disconnect fitting at the rear of the cooker
and to the building gas line.
NOTE: Some cookers are configured for a rigid connection to the gas supply line. These units
must be connected to the gas supply line at the rear of the unit using fittings approved for that
purpose by the appropriate regulatory agency of the county in which the appliance is installed.
NOTE: When using thread compound, use very small amounts on male threads only. Use a pipe
thread compound that is not affected by the chemical action of LP gases (i.e. propane, G31)
(Loctite™ PST56765 Sealant is one such compound). DO NOT apply compound to the first two
threads. This will ensure that the burner orifices and control valve do not become clogged.
2. Open the gas supply to the cooker and check all piping, fittings, and gas connections for leaks. A
soap 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 cooker at the main shut-off valve
and contact the local gas company or an authorized service agency for service.
3. Close the cooker drain valve and fill the cookpot with water and detergent. Light the cooker and
perform the boil-out procedures that are described in the “Lighting Instructions” and “Boiling Out
the Cookpot” topics found in Chapter 3 of this manual.
WARNING
“Dry-firing” this equipment will cause damage to the cookpot. Always ensure that
water is in the cookpot before firing your unit.
