HIGH EFFICIENCY DECATHLON (HD) SERIES GAS FRYERS
CHAPTER 3: INSTALLATION
3.4 Gas Connections (cont.)
Gas Supply Type and Pressure
Gas Supply Type | Gas Supply Pressure |
Natural Gas | 6-10" W.C. (Dynamic) |
Propane (LP) Gas | 11-13" W.C. (Dynamic) |
DANGER
When pressure-testing incoming gas supply lines, disconnect the fryer from the gas
line if the test pressure is ½" PSI [3.45 kPa (14 inches W.C.)] or greater to avoid
damage to the fryer’s gas piping and gas valve(s).
DANGER
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 service agency for service.
DANGER
"Dry-firing" your unit will cause damage to the frypot and can cause a fire. Always ensure that melted shortening, cooking oil or water is in the frypot before firing the unit.
A. Rigid Connections: Check any installer-supplied intake pipe(s) visually and clean threading chips, or any other foreign matter 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. Seal pipe joints with a sealant resistive to LP gas. 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.
B.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.
C.Regulating Gas Pressure: The fryer and shut-off valve must be disconnected from the gas supply during any pressure testing of the system.
NOTE: 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.
