GAS SUPPLY CONNECTION
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 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 _ettape. 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.
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"
[10 ram] male pipe thread.)
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.
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.
