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 propane gas,
3/8" propane 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 propane
gas must be used. Do not use TEFLON
