This dryer is equipped for use with natural gas. It is certied
by UL for use with propane gas with appropriate conversion.
No attempt shall be made to convert dryer from gas specied
on serial/rating plate for use with a different gas without
consulting the serving gas supplier. Conversion must be done
by a qualied service technician.
Gas conversion kit part numbers are listed on gas valve
burner base.
Type of Gas
DRYER GAS SUPPLY REQUIREMENTS
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 propane gas must be used. Do not use TEFLON
®†
tape.
With propane gas, piping or tubing size can be 1⁄2" (13 mm)
minimum. Usually, propane gas suppliers determine size and
materials used in the system.
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/m
2
).
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.
Gas Supply Line
Flexible Metal Appliance Connector
It is recommended that a new exible stainless steel gas line,
design-certied 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).
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 dryer.
