1. The fryer and its individual shut-off
valve must be disconnected from the
gas supply piping system during any
pressure testing of that system at
pressures in excess of ½ PSIG
(3.45KPa).
2. The fryer must be isolated from the gas
piping system by closing its individual,
manual shut-off valve during any
pressure testing of the gas supply
piping system at pressures equal to
more than ½ PSIG (3.45KPa).
b. Manual shut-off valve: This supplier-
installed valve must be installed in the gas
service line ahead of the appliance in the
gas stream and in a position where it can
be reached quickly in the event of an
emergency.
c. Pressure regulating:
1. External regulators are not normally
required on this fryer, as that function
is performed by a safety control valve.
2. Exception: If the incoming pressure
is in excess of ½” PSIG (3.45KPa), a
step-down regulator will be
required. Your local servicer
should check the manifold pressure
with a manometer – natural gas
units require 3.5” WC (8.71mbar)
and propane requires 10” WC
(25mbar).
d. Orifices: The fryer can be connected to
either natural or propane gas. The correct
safety control valve and appropriate gas
orifices are installed at the factory. While
the valve can be adjusted in the field, only
qualified service personnel should make
any adjustment with the proper test
equipment.
e. Rigid Connections: The fryer can be
connected singly or as part of a cooking
line. Check any installer-supplied intake
pipe(s) visually and clean threading chips
or any other foreign matter before
installing into a service line.
f. Flexible Couplings & Connectors:
1. If the unit is installed with couplings
or quick disconnect fittings, the
installer must use a heavy-duty, AGA
design-certified commercial connector
of at least ¾” NPT (with suitable
strain relief) in compliance with ANSI
Z-21.69-1979. Domestic connectors
are not suitable.
2. If the unit is installed with casters, the
installation should be made with a
connector that complies with the
Standard for Connectors for Moveable
Gas Appliances, ANSI Z21.69 or
Connectors for Moveable Gas
Appliances, CAN/CGA-6.16, and a
quick-disconnect device that complies
with the Standard for Quick
Disconnect Devices for Use with Gas
Fuel, ANSI Z21.41, or Quick
Disconnect for Use with Gas Fuel,
CANI-6.9, adequate means must be
provided to limit the movement of the
appliance without depending on the
connector and the quick disconnect
device or its associated piping to limit
the appliance movement. A
restraining bracket is provided on the
appliance structural back to prevent
the unit from moving from its
installed position.
CAUTION
ALL CONNECTIONS MUST BE SEALED
WITH A JOINT COMPOUND SUITABLE
FOR LP GAS, AND ALL CONNECTIONS
MUST BE TESTED WITH A SOAPY
SOLUTION BEFORE LIGHTING ANY
PILOTS.
