Installation Instruction

11
IMPORTANT: Observe all governing codes and ordinances.
This installation must conform with all local codes and
ordinances. In the absence of local codes, installation must
conform with American National Standard, National Fuel Gas
Code ANSI Z223.1/NFPA 54 or CAN/CSA B149.
A copy of the above code standards can be obtained from:

The design of this dryer has been certied by CSA International
for use at altitudes up to 10,000 ft (3,048 m) above sea level
at the B.T.U. rating indicated on the model/serial plate. Burner
input adjustments are not required when the dryer is operated
up to this elevation.
INSTALLATION REQUIREMENTSINSTALLATION REQUIREMENTS
When installed above 10,000 ft (3,048 m), a four percent
(4%) reduction of the burner B.T.U. rating shown on the model/
serial plate is required for each 1,000 ft (305 m) increase in
elevation. For assistance when converting to other gas types
and/or installing above 10,000 ft (3,048 m) elevation, contact
your local service company.
Gas supply pressure required to operate this dryer is
a minimum of 5.2" wc (1.30 kPa) and a maximum of
10.5" wc (2.62 kPa).
This dryer is equipped for use with natural gas. It is design-
certied by CSA International for propane and butane gases
with appropriate conversion. No attempt shall be made to
convert dryer from gas specied on serial/rating plate for use
with a different gas without consulting the serving gas supplier.
Conversion must be done by a qualied service technician.
Gas conversion kit part number is W10402145. This number
can also be found on a label on the gas valve burner base.
Type of Gas
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
). The dryer must be isolated
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
2
).
Expected Pressures For Gas Supply
Minimum
Inches of Water
Maximum
Inches of Water
Natural Gas 5.2 10.5
Propane Gas 8.0 13.0
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.
Flexible Metal Appliance Connector
It is recommended that a new exible stainless steel gas line,
design-certied 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 exible stainless steel gas
line when moving the dryer.
Rigid Pipe Connection
The rigid pipe connection requires a combination of pipe ttings
to obtain an in-line connection to the dryer.
