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.
This dryer must be connected to the gas supply line with
a listed flexible gas connector that complies with the standard
for connectors for gas appliances, CSA 6.10.
Option 1 (Recommended Method)
Flexible stainless steel gas connector:
If local codes permit, use a new flexible stainless steel gas
n
connector (Design Certified by CSA International) to connect
your dryer to the rigid gas supply line. Use an elbow and
a 9.5 mm (3/8") flare x 9.5 mm (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 6.1 m (20 ft.) can use 9.5 mm (3/8") approved
n
tubing (if codes and gas supplier permit).
If you are using Natural Gas, do not use copper tubing.
n
9.5 mm (3/8") flare x 9.5 mm (3/8") NPT adapter fitting
n
between dryer pipe and 9.5 mm (3/8") approved tubing.
Lengths over 6.1 m (20 ft.) should use larger tubing and
n
a different size adapter fitting.
If your dryer has been converted to use LP gas, 9.5 mm
n
(3/8") LP compatible copper tubing can be used. If the total
length of the supply line is more than 6.1 m (20 ft.), use
larger pipe.
NOTE: Pipe joint compounds that resist the action of LP
gas must be used. Do not use TEFLON

Burner input requirements

The design of this dryer is certified by CSA International for
use at altitudes up to 3,048 m (10,000 ft.) above sea level at
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.
When installed above 3,048 m (10,000 ft.), a 4% reduction
of the burner BTU rating shown on the model/serial
number plate is required for each 305 m (1,000 ft.)
increase in elevation.
The dryer must be disconnected from the gas supply piping
system during pressure testing at pressures greater than
352 kg/m (1/2 psi).
