L.P. gas conversion:
Conversion must be made by a qualified technician.
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.
IMPORTANT: The gas installation must conform with local codes,
or in the absence of local codes, with the National Fuel Gas Code,
ANSI Z223.1/NFPA 54.
Gas Supply Line:
■ ¹⁄₂" IPS pipe is recommended.
■ ³⁄₈" approved tubing is acceptable for lengths under 20 ft
(6.1 m) if local codes and gas supplier permit.
■ Must include ¹⁄₈" NPT minimum plugged tapping accessible
for test gauge connection, immediately upstream of the gas
connection to the dryer (see illustration).
■ Must include a shutoff valve:
An individual manual shutoff valve must be installed within
six (6) feet (1.8 m) of the dryer in accordance with the National
Fuel Gas Code, ANSI Z223.1. The location should be easy to
reach for opening and closing.
Gas supply connection requirements
There are many methods by which your gas dryer can be
connected to the gas supply. Listed here are some guidelines for
two different methods of connection.
Option 1 (Recommended Method)
Flexible stainless steel gas connector:
■ If local codes permit, use a new flexible stainless steel gas
connector (Design Certified by the American Gas Association
or CSA International) to connect your dryer to the rigid gas
supply line. Use an elbow and a ³⁄₈" flare x ³⁄₈" NPT adapter
fitting between the stainless steel gas connector and the dryer
gas pipe, as needed to prevent kinking.
Option 2 (Alternate Method)
Approved aluminum or copper tubing:
■ Lengths under 20 ft (6.1 m) can use ³⁄₈" approved tubing (if
codes and gas supplier permit).
■ If you are using natural gas, do not use copper tubing.
■ ³⁄₈" flare x ³⁄₈" NPT adapter fitting between dryer pipe and ³⁄₈"
approved tubing.
■ Lengths over 20 ft (6.1 m) should use larger tubing and a
different size adapter fitting.
■ If your dryer has been converted to use L.P. gas, ³⁄₈" L.P.
compatible copper tubing can be used. If the total length of
the supply line is more than 20 ft (6.1 m), use larger pipe.
NOTE: Pipe joint compounds that resist the action of L.P. gas
must be used. Do not use TEFLON

tape.
Dryer Gas Pipe
■ The gas pipe that comes out through the rear of your dryer
has a ³⁄₈" male pipe thread.

Burner Input Requirements:
Elevations up to 10,000 ft (3,048 meters):
■ The design of this dryer is certified 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 number plate.
Burner input adjustments are not required when the dryer is
operated up to this elevation.
Elevations above 10,000 ft (3,048 meters):
■ When installed above 10,000 ft (3,048 m) a 4% reduction of
the burner B.T.U. rating shown on the model/serial number
plate is required for each 1,000 ft (305 m) increase in elevation.
Gas Supply Pressure Testing
■ The dryer must be disconnected from the gas supply piping
system during pressure testing at pressures greater than
½ psi.
Venting Requirements
WARNING: To reduce the risk of fire, this dryer MUST BE
EXHAUSTED OUTDOORS.
4" (10.2 cm) heavy metal exhaust vent and clamps must be used.
DURASAFE™ venting products are recommended.
DURASAFE™ vent products can be purchased from your dealer
or by calling Whirlpool Parts and Accessories. For more
information, see the “Assistance or Service” section of your
“Dryer User Instructions.”
■ The dryer exhaust must not be connected into any gas vent,
chimney, wall, ceiling, or a concealed space of a building.
■ Do not use an exhaust hood with a magnetic latch.
■ Do not install flexible metal vent in enclosed walls, ceilings or
floors.
