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.

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
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.
