Patriot PT-GF100KNG, Installation & Operation Manual

2.4 Connection to Gas Line
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 pilot outage, slow recovery and delayed ignition. The incoming gas supply line
should be a minimum of 1½” (38 mm) in diameter. All single fryers using natural gas require a ¾”or 1/2" 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.
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.
• Connect a 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.
• 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.
NOTE: The fryer must be disconnected from the gas supply piping during any pressure testing of the gas supply
piping pressures equal to or greater than ½ psig (3.45kPa or 13.84 in. W.C.).
•
Close the fryer drain valve and fill the frypot with water or boil-out solution to the bottom OIL LEVEL line at
the rear of the frypot. Light the fryer and perform the boil-out procedures that are described in the “Start-Up
Procedure” and “Boiling Out the Frypot” found in S ection 3 of this manual.
WARNING
“Dry-firing” your unit will cause damage to the frypot. Always ensure that melted
shortening, cooking oil, or water is in the frypot before firing your unit.
•
It is suggested that the burner manifold pressure be checked at this time by the local gas company or an
authorized service agent. Refer to “Check Burner Manifold Pressure” in Section 4.3 of this manual for the
proper procedure.
