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 ram) rigid (IPS) pipe to dryer
location.
Pipe joint compounds
that resist action of LP gas must be
used. Do not use TEFLON °t tape. With LP gas, piping or tubing
size can be 1/2" (13 ram) 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 mm] 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.
