Henny Penny OFG-390 manual Gas Supply

		Model OFG- 390
2-6. GAS SUPPLY	•	The fryer must be isolated from the gas supply piping
(Continued)		system by closing its individual manual shutoff valve
		during any pressure testing of the gas supply piping
		system at test pressures equal to or less than 1/2
		PSIG (3.45 KPA) (34.47mbar).

•A standard 3/4 inch, black steel pipe and malleable fittings should be used for gas service connections.

•Do not use cast iron fittings.

•Although 3/4 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:

1.Installing a manual gas shut off valve and disconnect union, or

2.Installing a heavy duty (min. 3/4 inch) designA.G.A. certified connector which complies with standard connec- tors for moveable gas appliances. ANSI Z21.69 or CAN/CSA 6.16.Also, a quick disconnect coupling which complies with the Standard for Quick Disconnect De- vices for use with Gas Fuel, ANSI Z21.41 or CAN 1-6.9. Also, adequate means must be provided to limit the movement of the fryer without depending on the connec- tor and any quick-disconnect device or it’s associated piping to limit the fryer movement.

3.See the illustration on the following page for the proper connections of the flexible gas line and cable restraint.

The cable restraint limits the distance the fryer can be pulled from the wall. For cleaning and servicing the fryer, the cable must be unsnapped from the unit and the flexible gas line disconnected. This will allow better access to all sides of the fryer. The gas line and cable restraint must be reconnected once the cleaning or servicing is complete.
