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.
Type of Gas
GAS SUPPLY CONNECTION
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 ®† 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.
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.
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.
Gas Supply Line
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 which 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.
