Whirlpool CGD9150GW Installation Instructions Manual page 13

Type of Gas
This dryer is equipped for use with natural gas. It is design-
certified by CSA International for 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 number is W10402145. This number
can also be found on a label on the 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
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
from the gas supply piping system by closing the equipment
shut-off valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than 1/2" psig
(352 kg/m ).

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.

INSTALLATION REQUIREMENTS
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.
