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 or CSA 6.10.
BURNER INPUT REQUIREMENTS
Elevations above 10,000 ft. (3,048 m):
■
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
■
The dryer must be disconnected from the gas supply piping
system during pressure testing at pressures greater than
1/2 psi.
DRYER GAS PIPE
■
The gas pipe that comes out through the rear of your dryer
has a 3/8" male pipe thread.
A. 1/2" NPT gas supply line
B. 3/8" NPT dryer pipe
NOTE:
If the dryer is mounted on a pedestal, the gas pipe height
must be an additional 10" (254 mm) or 15.5" (394 mm) from the
floor, depending on the pedestal model. For a garage installation,
the gas pipe height must be an additional 18" (460 mm) from
the floor.
■
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 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 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 shutoff valve be installed within six (6) ft. (1.8 m) of
the dryer. The location should be easy to reach for opening
and closing.
A. 3/8" flexible gas connector
B. 3/8" pipe to flare adapter fitting
C. 1/8" NPT minimum plugged tapping
D. 1/2" NPT gas supply line
E. Gas shutoff valve.
LP Gas Conversion:
IMPORTANT:
Conversion must be made by a qualified
technician.
No attempt shall be made to convert the dryer 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.
