DRYER GAS CONNECTION
Option 1
Rigid gas supply line:
n
Connect your washer/dryer to the rigid gas supply line using
an elbow and a 3/8" flare x 3/8" NPT adapter fitting between
the stainless steel gas connector and the washer/dryer gas
pipe, as needed to prevent kinking.
Option 2
Approved aluminum or copper tubing:
n
3/8" approved aluminum or copper tubing is acceptable for
lengths under 20 ft. (6.1 m) if local codes and gas supplier
permit.
n
If you are using natural gas, do not use copper tubing.
n
Lengths over 20 ft. (6.1 m) should use larger tubing and
a different size adapter fitting.
n
If your washer/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

above sea level at the Btu rating indicated on the model/serial
number plate. Burner input adjustments are not required when
the washer/dryer is operated up to this elevation.
Elevations above 10,000 ft (3,048 meters):
n
When installed above 10,000 ft. (3,048 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.
