Gas Supply Requirements
Gas Type
Natural gas:
This dryer is equipped for use with natural gas. It is design-
certified by CSA International for L.P. (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, contact your dealer or
call the phone numbers referenced in the “Assistance or
Service” section of this manual.
L.P. gas conversion:
Conversion must be made by a qualified technician.
No attempt shall be made to convert the appliance from the gas
specified on the model/serial rating plate for use with a different
gas without consulting the serving gas supplier.
Gas supply line
■ ½" IPS 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 following illustration).
■ Must include a shutoff valve:
In the U.S.A.:
An individual manual shutoff 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.
In Canada:
An individual manual shutoff valve must be installed in
accordance with the B149.1, Natural Gas and Propane
Installation Code. It is recommended that an individual
manual shutoff valve be installed within six (6) feet (1.8 m) of
the dryer.
The 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.
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 under 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 L.P. gas, ³⁄₈" L.P.
compatible copper tubing can be used. If the total length of
the supply line is more than 20 ft (6.1 m), use larger tubing.
NOTE: Pipe joint compounds that resist the action of L.P. gas
must be used. Do not use TEFLON

tape.
WARNING
Explosion Hazard
Use a new AGA or CSA approved gas supply line.
Install a shut-off valve.
Securely tighten all gas connections.
If connected to LP, have a qualified person make sure
gas pressure does not exceed 13" (33 cm) water
column.
Examples of a qualified person include:
licensed heating personnel,
authorized gas company personnel, and
authorized service personnel.
Failure to do so can result in death, explosion, or fire.
