2.4 Connection to Gas Line
Before connecting new pipe to this appliance, the pipe must be blown out thor-
oughly to remove all foreign material. Foreign material in the burner and gas
controls will cause improper and dangerous operation.
The appliance and its individual shutoff valve must be disconnected from the gas
supply piping system during any pressure testing of the system at test pressures
in excess of ½ PSI (3.45 kPa, 13.84 inches W.C.) to avoid damage to the fryer's gas
tubes and gas valve(s).
The appliance must be isolated from the gas supply piping system by closing its
individual manual shutoff valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than ½ PSI (3.45 kPa, 13.84 inches
W.C.)
"Dry-firing" your unit will cause damage to the frypot and can cause a fire. Al-
ways ensure that cooking oil or water is in the frypot before firing the unit.
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 and immediately contact the local gas company or an authorized ser-
vice agency for service.
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
ignition. The incoming gas supply line
should be a minimum of 1½" (38 mm) in
diameter. Refer to the chart (right) for
the minimum sizes of connection
piping.
