Gas Supply Line:
• 1/2 in. IPS pipe is recommended.
• 3/8 in. approved tubing is acceptable
for lengths under 20 ft (6.1 m) if local
codes and gas supplier permit.
• Must include 1/8 in. NPT plugged tap*
ping, immediately upstream of the gas
connection (see illustration).
• Must include a shutoff valve.
An individual 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.
The location should be easy to reach
for opening and closing.
NOTE: Pipe joint compounds that resist
the action of L.P. gas must be used. Do
not use TEFLON _'tape.
Dryer Gas Pipe
• The gas pipe that comes out through
the rear of your dryer has a 3/8 in.
male pipe thread.

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.
Option 1 (Recommended Method):
Flexible stainless steel tubing:
• If local codes permit, use flexible
stainless steel tubing (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 in. flare x 3/8 in.
NPT adapter fitting between the stain-
less steel tubing and the dryer gas
pipe, as needed to prevent kinking.
Option 2 (Alternate Method):
Approved aluminum or copper tubing:
• Lengths under 20 ft (6.1 m) can use
3/8 in. approved tubing (if codes and
gas supplier permit).
• If you are using natural gas, do not
use copper tubing.
• 318in. flare x 318in. NPT adapter fitting
between dryer pipe and 318in.
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 L.R gas, 3/8 in. L.R compatible
copper tubing can be used. If the total
length of the supply line is more than
10 20 ft (6.1 m), use larger pipe.

Burner Input Requirements:
Elevations up to 10,000 feet:
• The design of this dryer is certified by
CSA International for use at altitudes
up to 10,000 ft (3,000 m) above sea
level at the B.T.U. rating indicated on
the model/serial number plate. Burner
input adjustments are not required
when the dryer is operated up to this
elevation.
Elevations above 10,000 feet:
• When installed above 10,000 ft
(3,000 m) a 4% reduction of the burn-
er B.T.U. 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
any pressure testing of that system at
test pressures in excess of 1/2 psi.
• The dryer must be isolated from the
gas supply piping system by closing
the supply line shutoff valve during
any pressure testing of the gas supply
piping system at test pressures equal
to or less than 1/2 psi.
