Installation
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 re-
cess.
•
Use a new flexible stainless steel connector.
•
Use pipe joint compound insoluble in L.P. (Lique-
fied Petroleum) Gas, or Teflon tape, on all pipe
threads.
•
Purge air and sediment from gas supply line be-
fore 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 per-
son.
1. Make certain your dryer is equipped for use with the type of
gas in your laundry room. 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 ab-
sence of local codes and ordinances, with the latest
edition of the National Fuel Gas Code ANSI Z223.1/
NFPA 54 or the CAN/CSA-B149.1 Natural Gas and
Propane Installation Code.

NOTE: When connecting to a gas line, an equipment
shut-off valve must be installed within 6 feet [1.8 m]
of the dryer. An 1/8 in. NPT pipe plug must be instal-
led as shown for checking inlet pressure. Refer to
Figure 11 .
