GAS SUPPLY LINE
n Must include 1/8" NPT minimum plugged tapping accessible
for test gauge connection, immediately upstream of the gas
connection to the washer/dryer. See illustration below.
n 1/2" IPS pipe is recommended.
n Must include shut-off valve:
In the U.S.A.:
An individual manual shut-off valve must be installed within
six (6) ft. (1.8 m) of the washer/dryer in accordance with the
National Fuel Gas Code, ANSI Z223.1. The location should
be easy to reach for opening and closing.
In Canada:
An individual manual shut-off valve must be installed in
accordance with the B149.1, Natural Gas and Propane
Installation Code. It is recommended that an individual
manual shut-off valve be installed within six (6) ft. (1.8 m)
of the washer/dryer. The location should be easy to reach
for opening and closing.
This washer/dryer is equipped with its own permanent,
flexible gas connector, design-certified by CSA International,
for connecting the washer/dryer to the gas supply line.

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 ®† tape.
GAS SUPPLY CONNECTION REQUIREMENTS
n Use an elbow and a 3/8" flare x 3/8" NPT adapter fitting
between the flexible gas connector and the washer/dryer gas
pipe, as needed, to avoid kinking.
n
Use only pipe-joint compound. Do not use TEFLON ®† tape.
BURNER INPUT REQUIREMENTS
Elevations up to 10,000 ft (3,048 meters):
n The design of this washer/dryer is certified by CSA
International for use at altitudes up to 10,000 ft (3,048 m)
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.
Gas supply pressure testing
n The washer/dryer must be disconnected from the gas supply
piping system during pressure testing at pressures greater
than 1/2 psi.
