A Backdraft Damper, Part No. 58786 (obtain locally),
should be installed in a 10.2 cm (4 inch) diameter
VERTICAL duct system. This will prevent a backdraft
when dryer is not in use, and will keep the exhaust air
in balance within the central exhaust system.
Step 3: (Gas Dryer Only) Connect Gas
Supply Pipe
1. Make certain your dryer is equipped for use with
the type of gas in your laundry room.
Dryers with “23” in last two characters of
model number: Dryer is equipped at the factory
for L.P. (Liquefied Petroleum) with a 3/8 inch
NPT gas connection.
All other models: Dryer is equipped at the
factory for Natural Gas with a 3/8 inch NPT gas
connection.
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/m

(1000 Btu/ft

) service must
be supplied at minimum 5.0 inch water column
pressure to maximum 10.5 inch water column
pressure.
For proper operation at altitudes above 610 m
(2000 feet) the natural gas valve spud orifice size must
be reduced to ensure complete combustion. Refer to
Table 2.

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.
