CHAPTER 2: INSTALLATION INSTRUCTIONS
2-5
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. The incoming
gas supply line should be a minimum of ½" (13 mm)
in diameter. Refer to the chart below for the
minimum sizes of connection piping.

1. Connect the quick-disconnect hose to the fryer quick-disconnect fitting under the front 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 to the gas supply line at the rear of the unit.
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 PST567 sealant is one
such compound). DO NOT apply compound to the first two threads. Applying compound to the
first two threads will cause clogging of the burner orifices and control valve.
2. Open the gas-supply valve to the fryer and check all piping, fittings, and gas connections for
leaks. A soap and water solution should be used for this purpose.
