Gas supply
requirements
OBSERVE ALL GOVERNING CODES AND
ORDINANCES.
If local codes permit, it is recommended that new
flexible metal tubing, design-certified by AGA or
CSA, be used for connecting the appliance to the
rigid gas supply line. (The gas pipe which extends
through the lower rear of the appliance has 3/8inch male pipe thread.)
An elbow and connector between tubing and dryer
pipe may be needed to prevent kinking.
A 1/8-inch NPT plugged tapping, accessible for test
gauge connection, must be installed immediately
upstream of the gas supply connection to the dryer.
The gas supply must have a shutoff valve. The valve
should be within six feet of the dryer and in the
same room. The location should be easy to reach for
opening and closing the valve.
The dryer and its individual shutoff valve must be
disconnected from the gas supply piping system
during any pressure testing of that system at test
pressures in excess of 1/2 psi.
The dryer must be isolated from the gas supply
piping system by closing its individual manual
shutoff valve during any pressure testing of the
gas supply piping system at test pressures equal
to or less than 1/2psi.
A combination of pipe fittings must be used to
obtain an in-line connection to the dryer.
Burner input requirements:
Elevations up to 10,000 feet:
The design of this dryer has been certified by CSA
International for use at altitudes up to 10,000 feet
above sea level at the B.T.U. rating indicated on the
model/serial rating plate. Burner input adjustments are
not required when the dryer is operated up to this
elevation.
Elevations above 10,000 feet:
When installed above 10,000 feet, a four percent (4%)
reduction of the burner B.T.U. rating shown on the
model/serial rating plate is required for each 1,000
foot increase in elevation. For assistance installing
dryer above 10,000 feet elevation, contact your
serving gas supplier.
Supply line requirements:
Gas requirements:
Check that dryer is
equipped with the correct
burner for the particular
type of gas in the home.
Burner information will be
found on the model/serial
rating plate in door well of
the dryer. If this information
does not agree with the type of
gas available, see your dealer.
Natural Gas:
This dryer is equipped for use with NATURAL
GAS. It is design-certified by CSA International for
L.P. (propane or butane) gases with appropriate
conversion.
L.P. Gas:
No attempt shall be made to convert the
appliance from the gas specified on the
model/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 the gas valve burner base.
Explosion Hazard
Use a new AGA or CSA approved gas
supply line.
Install a shut-off valve.
Securely tighten all gas connections.
If connected to LP, have a qualified
person make sure gas pressure does not
exceed 13" water column. Examples of a
qualified person include licensed heating
personnel, authorized gas company
personnel, and authorized service
personnel.
Failure to do so can result in death,
explosion, or fire.
WARNING
Provide a 1/2-inch IPS rigid gas supply line to the
dryer location.
When acceptable to the gas supplier and local codes,
3/8-inch approved tubing may be used for lengths
under 20 feet. For lengths over 20 feet, larger tubing
should be used.
An individual manual shutoff valve must be installed
within 6 feet of the dryer in accordance with the
National Fuel Gas Code ANSI Z223.1 – latest
edition*.
Pipe-joint compounds resistant to the action of L.P.
gas must be used.

Electrical
requirements
If codes permit and a separate ground wire is used, it
is recommended that a qualified electrician
determine that the ground path is adequate.
A 120-volt, 60-Hz, AC-only, 15- or 20-ampere fused
electrical supply is required. A time-delay fuse or
circuit breaker is recommended.
It is recommended that a separate circuit serving only
this appliance be provided.
A wiring diagram is located inside the console or on
the inside of the lower front panel.
Recommended ground method
The dryer, when installed, must be electrically
grounded in accordance with local codes, or in the
absence of local codes, with the National Electrical
Code ANSI/NFPA 70*.
GROUNDING INSTRUCTIONS: This appliance must
be grounded. In the event of malfunction or
breakdown, grounding will reduce the risk of electric
shock by providing a path of least resistance for
electric current.
The power supply cord plug must be plugged into
an appropriate outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.
WARNING - Improper connection of the equipmentgrounding conductor can result in a risk of electric
shock. Check with a qualified electrician or
serviceman if you are in doubt as to whether the
appliance is properly grounded. Do not modify the
plug provided with the appliance - if it will not fit the
outlet, have a proper outlet installed by a qualified
electrician.
