Gas Supply Line: |
| Gas supply connection requirements |
■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 ft (6.1 m) if local codes and gas supplier permit.
■If you are using Natural gas, do not use copper tubing.
■³⁄₈" flare x ³⁄₈" NPT adapter fitting between dryer pipe and ³⁄₈" 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 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:
■Must include a shutoff valve:
In the U.S.A.:
An individual manual 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.
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.

■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
■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 ½ psi.
Dryer Gas Pipe
■The gas pipe that comes out through the rear of your dryer has a ³⁄₈" male pipe thread.
