Gas Supply Requirements
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, contact your dealer or
call the phone numbers referenced in the “Assistance or
Service” section of this manual.
LP 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 your gas company.
Gas supply line
■ 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
®†
tape.
■ 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
■ 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
®†
tape.
■ 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.
Burner input requirements
Elevations above 2,000 ft (600 m):
■ When installed above 2,000 ft (600 m) a 4% reduction of the
burner Btu rating shown on the model/serial number plate is
required for each 1,000 ft (300 m) above sea level.
Gas supply pressure testing
■ The dryer must be disconnected from the gas supply piping
system during pressure testing at pressures greater than
½ psi.
WARNING
Explosion Hazard
Use a new CSA International 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.
