Gas Requirements . . .

(Gas Dryers)

NOTE: The gas service to a gas dryer must conform with the local codes and ordinances, or in the absence of local codes and ordinances, with the latest edition of the National Fuel Gas Code ANSI Z223.1/NFPA 54 or the CAN/CGA-B149, National Gas Installation Code.

Natural Gas, 37.3 MJ/m3 (1,000 Btu/ft3), service must be supplied at 6.5 ± 1.5 inch water column pressure.

For proper operation at altitudes above 610 m (2,000 feet) the natural gas valve spud orifice size must be reduced to ensure complete combustion. See table at right.

L.P. (Propane) Gas, 93.1 MJ/m3 (2,500 Btu/ft3), service must be supplied at 10 ± 1.5 inch water column pressure.

NOTE: DO NOT connect the dryer to L.P. (Propane) Gas Service without converting the gas valve. A 458P3 L.P. (Propane) Gas Conversion Kit must be installed by the Manufacturer’s Authorized Dealers, Distributors, or local service personnel.

NOTE: The dryer and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 3.45 kPa (1/2 psi).

The dryer must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than

3.45 kPa (1/2 psi)

NOTE: When connecting to a gas line, an equipment shutoff valve must be installed within 1.8 m (6') of the dryer. An 1/8" N.P.T. pipe plug must be installed as shown. See illustration.

WARNING

To reduce the risk of gas leaks, fire or explosion:

•The dryer must be connected to the type of gas as shown on nameplate located in the door recess.

•Use a new flexible stainless steel connector.

•Use pipe joint compound insoluble in LP (propane) Gas, or Teflon tape, on all pipe threads.

•Purge air and sediment from gas supply line before connecting it to the dryer. Before tightening the connection, purge remaining air from gas line to dryer until odor of gas is detected. This step is required to prevent gas valve contamination.

•Do not use an open flame to check for gas leaks. Use a non-corrosive leak detection fluid.
