The fryer must be isolated from the gas supply piping system by ciosing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than l/2 PSIG (3.45 kPa).
Astandard 3/4 inch, black steel pipe and malleable fittings should be used for gas service connections.
Do not use cast iron fittings.
Although 314 inch size pipe is recommended, piping should be of adequate size and installed to provide a supply of gas sufficient to meet the maximum demand without undue loss of pressure between the meter and the fryer. The pressure loss in the piping system should not exceed 0.3 inch water column.
Provisions should be made for moving the fryer for cleaning and servicing. This may be accomplished by:
I.Installing a manual gas shut off valve and disconnect union, or
2.Installing a heavy duty design A.G.A. certified connector which complies with standard connectors for moveable gas appliances.
ANSI 221.69 (the latest edition) or CAN 1 6. IOhM. Also, a quick disconnect coupling which complies with the Standard for Quick Disconnect Devices for use with Gas Fuel, ANSI 21.41 (the latest edition) or CAN I 6.9M79. Also, adequate means must be provided to limit the movement of the fryer without depending on the connector and any
3.See the illustration on the following page for the proper connections of the flexible gas line and cable restraint.
Prior to turning the gas supply on, be sure the gas dial cock on the fryer gas valve is in the OFF position.
After the piping and fittings have been installed, check for gas leaks. A simple checking method is to turn on the gas brush all connections with a soap solution. If bubbles and occur, it indicates escaping gas. In this event, the piping connection must be redone.
Never use a lighted maame to test for gas leaks. Escaping gas could cause an explosion resulting in severe personal injury and/or property damage.
