HIGH EFFICIENCY DECATHLON (HD) SERIES GAS FRYERS

CHAPTER 3: INSTALLATION

3.4 Gas Connections (cont.)

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).

D.Manifold Pressure: Your local service technician should check the manifold pressure with a manometer.

1.Check the rating plate for specific manifold gas pressures. Natural gas units normally require 4" W.C. (10.0 mbar), and propane/LP units normally require 11" W.C. (27.5 mbar) gas pressure.

2.Confirm that the arrow forged into the bottom of the regulator body, which indicates gas flow direction, is pointed downstream towards the fryers. The air vent cap is also part of the regulator and should not be removed. If a vent line from the gas pressure regulator is used, it should be installed in accordance with local codes or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1-(latest edition) in the U.S. and appropriate national or European Community (CE) standards in the European Union.

WARNING

Use a diluted soap solution to find potentially dangerous gas leaks when making

new connections.

E.Regulators can be adjusted in the field, but it is recommended that qualified service personnel adjust a regulator only if it is known to be out of adjustment or serious pressure fluctuations have been found and can not be solved another way.

F.Only qualified service personnel should make adjustments to the regulators.

G.Orifices: The fryer can be configured to operate on any available gas. The correct safety control valve, appropriate gas orifices, and pilot burner are installed at the factory. While the valve can be adjusted in the field, only qualified service personnel should make adjustments with proper test equipment.

H.Flexible Couplings, Connectors and Casters: If the fryer is to be installed with flexible couplings and/or quick-disconnect fittings, the installer must use a heavy-duty AGA design-certified commercial flexible connector of at least ¾" NPT (with suitable strain relief), in compliance with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69-(latest edition) and Addenda Z21.69a-(latest edition). Quick disconnect devices must comply with the Standard for Quick-Disconnect Devices for Use with Gas Fuel, ANSI Z21.41-(latest edition).

1.For an appliance equipped with casters, the installation in the U.S. shall be made with a connector that complies with Standard for Connectors for Movable Gas Appliances, ANSI Z21.69-(latest edition) and Addenda Z21.69a-(latest edition). In the European Union, use a flexible coupling certified as NF D 36123 (or other national standard) or a quick disconnect device certified NF D 36124 (or other national standard).
