YSCFHC18G HIGH EFFICIENCY COOL ZONE SERIES GAS FRYERS
CHAPTER 3: INSTALLATION INSTRUCTIONS
3-5
3.4 Gas Connections (cont.)
DANGER
"Dry-firing" your unit will cause damage to the frypot and can cause a fire. Before
firing the unit, always ensure that melted shortening, cooking oil, or water is in the
frypot.
DANGER
Before connecting new pipe to this appliance, the pipe must be blown out
thoroughly to remove all foreign material. Foreign material in the burner and gas
controls will cause improper and dangerous operation.
Rigid Connections
Check any installer-supplied intake pipe(s) visually and clean metal particles or other foreign matter
from the threads before installing into a service line. If the intake pipes are not clear of all foreign
matter, the orifices will clog when gas pressure is applied. When using thread compound on gas
piping, use very small amounts and only on male threads. Use a pipe thread compound that is not
affected by the chemical action of LP gases. DO NOT apply thread compound to the first two pipe
threads—doing so will cause clogging of the burner orifices and control valve.
Manual Shut-off Valve
This gas service supplier-installed valve must be installed in the gas service line ahead of the fryers
in the gas stream and in a position where it can be reached quickly in the event of an emergency.
Regulating Gas Pressure
The fryer and its individual shut-off valve must be disconnected from the gas supply piping system
during any pressure testing of the gas supply system, especially if the test pressures are in excess of
½ PSI (3,45 kPa/35 mbar).
External gas regulators are not normally required on this fryer. A safety control valve protects the
fryer against pressure fluctuations. If the incoming pressure is in excess of ½ PSI (3,45 kPa/35
mbar), a step-down regulator is required.
DANGER
When pressure-testing incoming gas supply lines, disconnect the fryer from the gas
line if the test pressure is 3,45 kPa (½ PSI, 14" W.C.) or greater to avoid damage to
the fryer’s gas piping and gas valve(s).
