Frymaster GF40 Series Installation & Operation Manual page 13

The size of the gas line used for installation is important. If the line is too small, the gas pressure at
the burner manifold will be low. This will cause pilot outage, slow recovery and delayed ignition.
The incoming gas supply line should be a minimum of 1½" (38 mm) in diameter. All single
GF14/GF40 fryers using natural gas require a ¾" connection. Batteries of two and three fryers
require a 1" connection. For fryers using LP gas, one pipe size smaller may be used. If in doubt
about the correct pipe size, consult the local gas company.
NOTE: Runs of more than 20 feet and more than 4 fittings or elbows require an increase of one
pipe size, i.e., ¾" to 1" or 1" to 1¼".
Before connecting new pipe to your unit, the pipe must be thoroughly blown out to remove any
foreign particles, which can cause improper and sometimes dangerous operation.
1. Connect the quick-disconnect hose to the fryer quick-disconnect fitting at the rear of the fryer
and to the building gas line.
NOTE: Some fryers are configured for a rigid connection to the gas supply line. These units
are connected directly to the gas supply line.
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 (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 fryer and check all piping, fittings, and gas connections for leaks. A
soap and water solution should be used for this purpose.
All connections must be sealed with a joint compound suitable for the gas being
used and all connections must be tested with a solution of soapy water before
lighting any pilots.
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 appliance at the main shut-off valve or bottle.
● Extinguish all naked flames.
● Do not operate any electrical appliances in the area.
● Ventilate the area.
● Check for leaks as detailed in this manual using a solution of soapy solution.
● Immediately contact the local gas company or an authorized service agency for
service.
If odor persists, contact the dealer or gas supplier immediately.
NOTE: The fryer must be disconnected from the gas supply piping during any pressure testing
of the gas supply piping at pressures equal to or greater than ½ psig (3.45kPa or 13.84 in. W.C.).
