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

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
½ psi.
