3.4 Gas Connections (cont.)
E. Manifold Pressure: Only qualified personnel should check the manifold pressure with a
manometer.
1. Check the rating plate for manifold gas pressures. Natural gas units normally require 4"
W.C., and propane units normally require 11" W.C. gas pressure.
2. Double check the arrow forged into the bottom of the regulator body, which indicates
gas flow direction. It should point downstream towards the fryers. The air vent cap is
also part of the regulator and should not be removed.
3. 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).
WARNING
Use a diluted soap solution to find potentially dangerous gas leaks when making
new connections.
F. Regulators can be adjusted in the field, but it is recommended that they not be tampered with
unless the part is known to be out of adjustment or serious pressure fluctuations are found to
exist and can be solved no other way.
G. Only qualified service personnel should make adjustments to the regulators.
H. 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 any
adjustments with the proper test equipment.
I. Flexible Couplings, Connectors and Casters:
1. 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 3/4" NPT (with suitable strain reliefs), 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).
WARNING
Do not attach accessories to this fryer unless fryer is secured from tipping. Personal
injury may result.
2. The fryer must be restrained by means independent of the flexible coupling or
connector in order to limit the movement of the fryer. Clips are located on the back
panel of the fryer for the attachment of restraints.
