Gas Supply Line
•
The gas supply line should be ½" (1.3 cm) pipe and must have an individual
manual shuto valve installed within 6 ft (183 cm) of the dryer in accordance with
the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or in Canada with the Natural
Gas and Propane Installation Code, B149.1.
•
The shuto valve should be easy to reach for opening and closing.
•
A
" NPT minimum plugged tapping, accessible for test gage connection, must
be installed immediately upstream of the gas supply connection to the dryer.
•
The supply line should terminate with a

GAS SUPPLY CONNECTION REQUIREMENTS
This dryer must be connected to the gas supply line with a listed exible gas
connector that complies with the standard for connectors for gas appliances, ANSI
Z21.24 or CSA 6.10.
Flexible stainless steel gas connector:
•
If local codes permit, use a new exible stainless steel gas connector (Design
Certi ed by the American Gas Association or CSA International) to connect your
dryer to the rigid gas supply line. Use an elbow and a
tting between the stainless steel gas connector and the dryer gas pipe, as
needed to prevent kinking.
BURNER INPUT REQUIREMENTS
Elevations up to 10,000 ft. (3,048 m):
•
The design of this dryer is certi ed 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 (3.5kPa).
