CHAPTER 3: INSTALLATION INSTRUCTIONS
3-6
3.4 Gas Connections (cont.)
A. Manifold Pressure: Your local service technician 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. 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.
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.
B. Regulators: Gas regulators can be adjusted in the field, but no adjustments should be made
unless the regulator is out of adjustment or serious pressure fluctuations are observed.
C. Only qualified service personnel should make adjustments to the regulators.
D. Orifices: The fryer can be ordered to operate on any available gas. The correct
combination gas valve, appropriate burner orifices, and pilot burners 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.
DANGER
If gas odors are detected, the gas supply must be shut off at the main shut-off valve.
The local gas company or FASC should be contacted immediately to fix the problem.
E. 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 ¾" NPT (with suitable strain-relief attachments), 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).
