Use a new CSA International 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" (33 cm) 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.
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 in
your home. 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, contact your local Sears
store or Sears Service Center.
LP 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 your gas company.

" NPT minimum plugged tapping accessible
for test gauge connection, immediately upstream of the gas
connection to the dryer (see illustration).
" IPS pipe is recommended.
" approved aluminum or copper tubing is acceptable for

Gas Supply Requirements

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,
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
Must include a shutoff valve:
An individual shutoff valve must be installed within 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.

the Btu 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 Btu rating shown on the model/serial number plate
is required for each 1,000 ft (305 m) increase in elevation.
