Gas Supply Line; Burner Input Requirements; Gas Supply Connection Requirements - Kenmore 11075202310 Installation Instructions Manual

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 shut-off valve:
In the U.S.A.:
An individual manual shut-off 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.
In Canada:
An individual manual shut-off valve must be installed in accordance
with the B149.1, Natural Gas and Propane Installation Code. It is
recommended that an individual manual shut-off valve be installed
within six (6) feet (1.8 m) of the dryer.
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 I (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 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 _et 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.
