Check that exhaust system is
not longer ttian specified.
Exhaust systems longer than
specified will:
- Accumulate Ilnt.
- Shorten the life of the product.
- Reduce performance,
resulting In longer drying
times and Increased energy
usage.
Failure to follow spectfications-,
may result In a fire.

Side or Bottom Exhaust: The
maxlmum length of the exhaust
system If dryer is exhausted out the
side or bottom is 16 feet with two
external elbows and hood.
Service check: The back pressure In
any exhaust system used must not
exceed 0.6 Inches of water column
measured with an inclined
manometer at the point that the
exhaust system connects to the
dryers.
If the dryers are installed in a
confined area, they must be
exhausted to the outside and
provislon must be made for
enough air for combustion and
ventilation. Check governlng
codes and ordinances. Also refer.
to the ‘Recessed area and closet
installation instructions.’ Page 9.
An exhaust hood should cap the
exhaust duct to prevent exhausted
air from returnlng into the dryers.
The outlet hood must be at least 12
inches from the ground or any
object that may be In the path of
the exhaust.
A main exhaust duct can be used
for exhausting a group of dryers.
Main exhaust duct should be sized
to remove 200 CFM of alr per
dryer. Large-capacity lint screens
of proper design may be used In
the main exhaust duct if checked
and cleaned frequently. The room
where the dryers are located
.
should have make-up air equal to
or greater than the CFM of all the
dryers in the room.
