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 (see illustration).
• 1/2" IPS pipe is recommended.
• 3/8"approved aluminum or copper tubing is acceptable for lengths under 20 ff (6.1 m) if
local codes and gas supplier permit.
• If you are using Natural gas, do not use copper tubing.
• %" flare x %" NPT adapter fitting between dryer pipe and %" approved tubing.
• Lengths over 20 fl (6.1 m) should use larger tubing and a different size adapter fitting.
• If your dryer has been converted to use [.P gas, %" I.P 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 IP gas must be used. Do not use
TEFI.ON '_ tape.
• Must include a shutoff valve:
In the U.S.A.:
An individual manual shutoff w_lve must be installed within six (6) feet (1.8 m) of the dryer
in accordance with the National Fuel Gas Code, ANSI Z223.1.
In Canada:
An individual manual shutoff 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) feet (1.8 m) of the dryer. The location should be
easy to reach for opening and closing.

Gas supply connection requirements
• Use an elbow and a %" flare x %" 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 TEFI.ON '_ttape.
• 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 r'n) a 4% reduction of the burner Btu rating shown
on the model/serial number plate is required for each ,000 ft (_¢05 m) increase in
elevation.
Gas Supply Pressure Testing
• ]he dryer must be disconnected from the gas supply piping system during pressure testing
at pressures greater than _/J psi.
Dryer Gas Pipe
]he gas pipe that comes out through the rear of your dryer has a %" male pipe thread.
