System
IMPORTANT:
Keep exhaust
duct as short as
possible.
NOTE:
Be certain old ducts are cleaned
before
installing
your new dryel.
For best drying results, recommended
maximum
length of exhaust system is shown in Table 2.
To prevent backdraft
when dryer is not in operation,
outer end of exhaust pipe must have a weather hood
with hinged dampers
(obtain locally).
NOTE: Weather
hood should be installed
at least
12 inches (30.5 cm) above the ground.
Larger
clearances
may be necessary
in areas where heavy
snowfall
can occm.
Exhaust
Direction
The dryer can be exhausted
to the outdoors
through the
back, left, right or bottom of the dryer. EXCEPTION:
Gas dryers cannot be vented out the left side
because of the burner housing.
Dryer is shipped from factory ready for rear exhaust;
no kits required.
Exhausting
the dryer through sides or bottom can be
accomplished
by installing
a DK1 Sales Accessory
(Directional
Exhaust
Kit 528P3) available
as optional
equipment
at extra cost.
