Gas Supply Requirements
Gas type
Natural gas:
This dryer is equipped for use with Natural Gas. It is design-
certified by CSA International for LP (propane or butane) gases
with appropriate conversion.
■
Your dryer must have the correct burner for the type of gas
at your location. Burner information is located on the rating
plate in the door well of your dryer. If this information does
not agree with the type of gas available, please contact your
local Sears store or Sears Service Center.
LP gas conversion:
Conversion must be made by a qualified technician.
No attempt should be made to convert the dryer from the gas
specified on the model/serial rating plate for use with a different
gas without consulting the serving gas supplier.
Gas supply line
■
1/2" NPT 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 shut off valve 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 over 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 LP gas, 3/8" LP
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 LP
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 m):
■
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 m):
■
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 1/2 psi.
