Gas type
Natural gas:
This dryer is equipped for use with Natural Gas. It is design-
certified by CSA International for LP (propane or butane) gases
with appropriate conversion.
Your dryer must have the correct burner for the type of gas
■
in your home. Burner information is located on the rating
plate in the door well of your dryer. If this information does
not agree with the type of gas available, please reference the
"Assistance or Service" section of the Use and Care Guide.
LP gas conversion:
Conversion must be made by a qualified technician.
No attempt shall be made to convert the dryer from the gas
specified on the model/serial rating plate for use with a different
gas without consulting the serving gas supplier.
IMPORTANT: The gas installation must conform with local codes,
or, in the absence of local codes, with the National Fuel Gas
Code, ANSI Z223.1/NFPA 54.
Gas supply line
1/2" NPT pipe is recommended.
■
3/8" approved tubing is acceptable for lengths under
■
20 ft. (6.1 m) if local codes and gas supplier permit.
Must include 1/8" NPT minimum plugged tapping accessible
■
for test gauge connection, immediately upstream of the gas
connection to the dryer (see illustration).
Must include a shut-off valve:
■
In the U.S.A.:
An individual manual shut-off valve must be installed
within six (6) feet (1.8 m) of the dryer in accordance with
the National Fuel Gas Code, ANSI Z223.1.
The shut-off valve location should be easy to reach for opening
and closing.

Gas supply connection requirements
There are many methods by which your gas dryer can be
connected to the gas supply. Listed here are some guidelines
for two different methods of connection.
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.

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:
Lengths over 20 ft. (6.1 m) can use 3/8" approved tubing
■
(if codes and gas supplier permit).
If you are using Natural Gas, do not use copper tubing.
■
3/8" flare x 3/8" NPT adapter fitting between dryer pipe and
■
3/8" approved 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
Dryer gas pipe
The gas pipe that comes out through the rear of your dryer
■
has a 3/8" male pipe thread.
Burner input requirements
D
Elevations up to 10,000 ft. (3,048 m):
The design of this dryer is certified by CSA International for
■
use at altitudes up to 10,000 ft. (3,048 m), above sea level at
the B.T.U. rating indicated on the model/serial number plate.
Burner input adjustments are not required when the dryer is
operated up to this elevation.
Elevations above 10,000 ft. (3,048 m):
When installed above 10,000 ft. (3,048 m) a 4% reduction
■
of the burner B.T.U. 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.
