Whirlpool FRONT-LOADING GAS DRYER manual Burner input requirements, Gas supply pressure testing

■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.

Gas supply connection requirements

■For close clearances, a ³⁄₈" to ³⁄₈" elbow is recommended to avoid kinking of the gas line.

■Use only pipe-joint compound. Do not use TEFLON®† tape.

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 gas connector:

■If local codes permit, use a new flexible stainless steel gas connector (Design Certified by CSA International) to connect your dryer to the rigid gas supply line. Use an elbow and a ³⁄₈" flare x ³⁄₈" NPT adapter fitting between the stainless steel gas connector and the dryer gas pipe, as needed to avoid kinking.

Option 2 (Alternate method)

Approved aluminum or copper tubing:

■Lengths under 20 ft (6.1 m) can use ³⁄₈" approved tubing (if 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 tubing.

NOTE: Pipe-joint compounds that resist the action of LP gas must be used. Do not use TEFLON®† tape.

Burner input requirements

Elevations up to 10,000 ft (3,048 m):

■The design of this dryer is certified by CSA International for use at altitudes up to 10,000 ft (3,048 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 ft (3,048 m):

■When installed above 10,000 ft (3,048 m) a 4% reduction of the burner 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 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.
