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, 1,000 Btu/ft

(37.3 MJ/m

), service
must be supplied at 6.5 ± 1.5 inch water column
pressure.
For proper operation at altitudes above 2,000 ft.
(610 m) the natural gas valve spud orifice size must be
reduced to ensure complete combustion. Refer to
Table 1.
L.P. (Liquefied Petroleum) Gas, 2,500 Btu/ft

(93.1 MJ/m

water column pressure.
NOTE: DO NOT connect the dryer to L.P. Gas
Service without converting the gas valve. A 458P3
L.P. 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 1/2 psi (3.45 kPa).
NOTE: When connecting to a gas line, an equipment
shutoff valve must be installed within 6 ft. (1.8 m)
of the dryer. An 1/8 in. N.P.T. pipe plug must be
installed as shown. Refer to Figure 38.

Table 1
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 L.P.
(Liquefied Petroleum) 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.
• Any disassembly requiring the use of
tools must be performed by a suitably
qualified service person.
