GAS SUPPLY LINE
Option 1 (Recommended Method)
Flexible stainless steel gas connector:
If local codes permit, use a new flexible stainless steel gas
■
connector (Design Certified by the American Gas Association
or CSA International) to connect your dryer to the rigid gas
supply line. Use an elbow and a 3/8" flare x 3/8" NPT adapter
fitting between the stainless steel gas connector and the dryer
gas pipe, as needed to prevent kinking.
Option 2 (Alternate Method)
Approved aluminum or copper tubing:
Must include 1/8" NPT minimum plugged tapping accessible
■
for test gauge connection, immediately upstream of the gas
connection to the dryer. See illustration.
1/2" IPS pipe is recommended.
■
3/8" approved aluminum or copper tubing is acceptable for
■
lengths under 20 ft. (6.1 m) if local codes and gas supplier
permit.
If you are using Natural gas, do not use copper tubing.
■
Lengths over 20 ft. (6.1 m) should use larger tubing and
■
a different size adapter fitting.
If your dryer has been converted to use LP gas, 3/8" LP
■
compatible copper tubing can be used. If the total length of the
supply line is more than 20 ft. (6.1 m), use larger pipe.
NOTE: Pipe-joint compounds that resist the action of LP gas
must be used. Do not use TEFLON
Must include shut-off valve
■
In the U.S.A.:
An individual manual shut-off valve must be installed within
six (6) ft. (1.8 m) of the dryer in accordance with the National
Fuel Gas Code, ANSI Z223.1. The location should be easy to
reach for opening and closing.
In Canada:
An individual manual shut-off valve must be installed in
accordance with the B149.1, Natural Gas and Propane
Installation Code. It is recommended that an individual
manual shut-off valve be installed within six (6) ft. (1.8 m) of
the dryer. The location should be easy to reach for opening
and closing.

GAS SUPPLY CONNECTION REQUIREMENTS
Use an elbow and a 3/8" flare x 3/8" NPT adapter fitting
■
between the flexible gas connector and the dryer gas pipe,
as needed to avoid kinking.
Use only pipe-joint compound. Do not use TEFLON
■
This dryer must be connected to the gas supply line with a
■
listed flexible gas connector that complies with the standard for
connectors for gas appliances, ANSI Z21.24 or CSA 6.10.
BURNER INPUT REQUIREMENTS
Elevations above 2,000 ft. (610 m):
When installed above 2,000 ft. (610 m) a 4% reduction of the
■
burner Btu rating shown on the model/serial number plate is
required for each 1,000 ft. (305 m) increase in elevation.
Gas supply pressure testing
The dryer must be disconnected from the gas supply piping
■
system during pressure testing at pressures greater than
1/2 psi.
DRYER GAS PIPE
The gas pipe that comes out through the rear of your dryer has
■
a 3/8" male pipe thread.

* NOTE: If the dryer is mounted on a pedestal, the gas
pipe height must be an additional 10" (254 mm) or
15.5" (394 mm) from the floor, depending on the pedestal
model. For a garage installation, the gas pipe height must
be an additional 18" (460 mm) from the floor.
