GAS SUPPLY CONNECTION
Type of Gas
This dryer is equipped for use with natural gas. It is certified by UL
for use with propane gas 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
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" 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.

Flexible Metal Appliance Connector
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 that extends through the lower
rear of the dryer is provided with 3/8" male pipe thread.)
NOTE: Do not kink or damage the flexible stainless steel gas line
when moving the dryer.
Rigid Pipe Connection
The rigid pipe connection requires a combination of pipe fittings to
obtain an in-line connection to the dryer.
