GAS SUPPLY CONNECTION
Type of Gas
This dryer is equipped for use with natural gas. It is design-
certi ed by CSA International for LP (propane and butane)
gases with appropriate conversion. No attempt shall be made
to convert dryer from gas speci ed on serial/rating plate for use
with a different gas without consulting the serving gas supplier.
Conversion must be done by a quali ed service technician.
Gas conversion kit part numbers are listed near gas valve
burner base.
Gas Supply Line
Recommended Method
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
piping or tubing size can be 1⁄2" (13 mm) minimum. Usually, LP
gas suppliers determine size and materials used in the system.
Gas Supply Pressure Testing
A 1/8" 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/m

10.5" (266.7 mm)
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.

Flexible Metal Appliance Connector
It is recommended that a new exible stainless steel gas line,
design-certi ed 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" male
pipe thread.)
NOTE: Do not kink or damage the exible stainless steel gas
line when moving the dryer.
Rigid Pipe Connection
The rigid pipe connection requires a combination of pipe ttings
to obtain an in-line connection to the dryer.
