DRYER GAS SUPPLY REQUIREMENTS

Type of Gas

This dryer is equipped for use with natural gas. It is design- certified by CSA International for LP (propane and butane) gases with appropriate conversion. No attempt shall be made to convert dryer from gas specified on serial/rating plate for use with a different gas without consulting the serving gas supplier. Conversion must be done by a qualified service technician.

Gas conversion kit part numbers are listed on gas valve burner base.

Gas Supply Line

Recommended Method

Flexible Metal Appliance Connector

Provide a gas supply line of 1⁄2" (13 mm) rigid (IPS) pipe to dryer location. Pipe joint compounds that resist action of LP gas must be used. Do not use TEFLON®† tape. With LP gas, piping or tubing size can be 1⁄2" (13 mm) minimum. Usually, LP gas suppliers determine size and materials used in the system.

It is recommended that a new flexible stainless steel gas line, design-certified by CSA International, be used for connecting the dryer to the gas supply line. (The gas pipe which extends through the lower rear of the dryer is provided with 3⁄8"

(10 mm) male pipe thread.)

Gas Supply Pressure Testing

A 1/8" (3 mm) NPT minimum plugged tapping, accessible for gauge testing, must be installed immediately downstream of the installed shut-off valve to the dryer (as shown above). The dryer must be disconnected from the gas supply piping system during any pressure testing of the system at test pressures in excess of 1/2" psig (352 kg/m2).

Alternate Method

The gas supply may also be connected using 3⁄8" (10 mm) approved copper or aluminum tubing. If the total length of the supply line is more than 20 ft. (6.1 m), larger tubing will be required.

If using natural gas, do not use copper tubing. Pipe joint compounds that resist action of type of gas supplied must be used.

Shut-off valve required

The supply line must be equipped with a manual shut-off valve installed within 6 ft. (1.8 m) of dryer in accordance with National Fuel Gas Code, ANSI Z223.1. This valve should be located in same room as dryer. It should be in a location that allows ease of opening and closing. Do not block access to shut-off valve. In Canada, an individual manual shut-off valve must be installed in accordance with the B149 installation

codes CAN/CGA B149.1 and CAN/CGA B149.2.

NOTE: Do not kink or damage the flexible stainless steel gas line when moving the door.

Rigid Pipe Connection

The rigid pipe connection requires a combination of pipe fittings to obtain an in-line connection to dryer.
