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).
EXHAUST SYSTEM REQUIREMENTS
IMPORTANT: The dryer must be exhausted to the outdoors.
The dryer shall not be exhausted into any gas vent, chimney, wall, ceiling, attic,
crawl space, or concealed space of a building.
DUCTING
If your current exhaust system is constructed of plastic or metal foil exible
ducting, replace it with rigid metal ducting.
Use only 4 (10.2 cm) diameter rigid metal ducting.
When making turns in the ductwork, use 45° elbows rather than 90° elbows. This
provides better air ow and can reduce the accumulation of lint in the exhaust
system.
Do not exceed the length of duct pipe for the number of elbows shown in the
chart below. Doing so can cause an accumulation of lint, an increase in drying
time, and the creation of a re hazard.
Two 45° elbows equal one 90° elbow.
