1.4.1. GAS CONNECTION
Your gas appliance will give you peak performance when the gas supply line is of sufficient size to
provide the correct gas pressure. The gas line must be installed to meet the local building codes or
National Fuel Gas Code ANSI Z223.1 Latest Edition. In Canada, install the appliance in accordance
with CAN/CGA-B149.1 or .2 and local codes. In Australia, install the appliance in accordance with
AS/NZS 5601. Gas line sizing requirements can be determined by your local gas company or, in
North America, by referring to the National Fuel Gas Code, Appendix C, Table C-4 (for natural gas)
and Table C-16 (for propane). The gas line needs to be large enough to supply the necessary amount
of fuel to all appliances without losing pressure
to any appliance. A properly sized and installed gas
line will deliver a supply pressure between 7.0” W.C. (17.4mbars, 1.74kPa) and 10.0”W.C.
(24.9mbars, 2.49kPa) natural gas or between 11.0”W.C. (27.4mbars, 2.74kPa) and 13.0” W.C.
(32.4mbars, 3.25kPa) for propane to all appliances connected to the supply line, operating
simultaneously at full demand. The pressure at the gas valve shall not exceed ½ PSI.
The gas supply connection to this appliance is located in the rear of the appliance approximately
10-1/2” (26.7 cm) from the floor of the appliance when legs are used.
Each appliance is equipped to operate on one certain fuel type. The type of fuel with which the
appliance is intended to operate is stamped on the data plate, which is attached to the inside of the
door.
WARNING
The fryer must be restrained from tipping to prevent spilling of hot liquid. The fryer shall
be restrained from tipping when installed, such as by connection to other appliances,
installation in an alcove, or by separate means such as a mechanical tie to structural
features. In the case where a mechanical tie is used, the fryer shall not be operated
without first checking that the mechanical tie is in place.
1.4.2. QUICK DISCONNECT CONNECTION
In North America, gas appliances equipped with casters must be installed with connectors that
comply with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69.CSA 6.16
Latest Edition. This connection should include a quick disconnect device that complies with the
Standard for Quick Disconnect Devices for Use With Gas Fuel Appliances ANSI Z21.41.CSA 6.9
Latest Edition. In Australia, an appliance equipped with casters and a flexible gas line must be
connected to the gas supply with a quick disconnect device that complies with AS 4627 and a
restraining cable. The restraining cable must not exceed 80% of the length of the flexible gas line.
The restraining device should be attached to the appliance at the back panel.
1.4.3. FUEL SUPPLY LINE LEAK AND PRESSURE TESTING
The fuel supply system must be tested before the appliance is used. If the fuel line is going to be
tested at a pressure greater than ½ PISG (3.45 kPa, 34.5 mbar), insure that that appliance is
disconnected from the fuel line. If the fuel line is to be tested at a pressure equal to or less than ½
PSIG (3.45 kPa, 34.5 mbar), the appliance can be connected during the test, but the unit’s gas
valve must be shut. Test all gas line connections for leaks with a solution of soap and water when
pressure applied.
1.4.4. INSTALLATION SETUP
The installation of this appliance
MUST
conform to local codes. In the absence of local codes in
North America, the installation must conform with the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 or the Natural Gas and Propane Installation Code CSA B149.1 as applicable. In
Australia, the appliance must installed in compliance with AS/NZS 5601 (current revision).
WARNING
NEVER supply the appliance with a gas other than the one that is indicated on the data
plate. Using the incorrect gas type will cause improper operation and could result in serious
injury or death. If you need to convert the appliance to another type of fuel, contact the
dealer you purchased it from.
NOTICE
NEVER use an adapter to make a smaller gas supply line fit the appliance connection. This
may not allow proper gas flow for optimum burner operation, resulting in poor performance
and improper operation.
