2-6. GAS SUPPLY (Continued)
Model
•The fryer and its manual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 PSIG (3.45 kPa) (34.5 mbar).
•The fryer must be isolated from the gas supply piping 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) (34.5mbar).
•A standard one inch (2.54 cm), black steel pipe and malleable fittings should be used for gas service connec- tions for 3 & 4 well open fryers, and 3/4 inch (1.91 cm) for 2 wells.
•Do not use cast iron fittings.
•Although one inch (2.54 cm) size pipe is recommended for 3 & 4 wells and 3/4 inch (1.91 cm) for 2 wells, 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 open fryer. The pressure loss in the piping system should not exceed 0.3 in. water column (0.747 mbar).
Provisions should be made for moving the open fryer for clean- ing and servicing. This may be accomplished by:
1.Installing a manual gas shutoff valve and a disconnect or union, or
2.Installing a
3.See the illustration on the following page for the proper connection of flexible gas line and cable restraint.
The cable restraint limits the distance the open fryer can be pulled from the wall. For cleaning and servicing the unit, the cable must be unsnapped from the open fryer and the flexible gas line disconnected. This allows better access to all sides of the open fryer. The gas line and cable restraint must be reconnected once the cleaning or servicing is complete.
