EXHAUST INFORMATION
CAUTION, FOR PERSONAL SAFETY:
- The dryers must be exhausted to the outside.
- Do not use non metallic flexible ducL
- Never use flexible duct inside the dryer.
- Do not terminate exhaust in a chimney, range hood, gas
vent, floor or attic. The combination of lint and grease
could create a fire hazard or damages.
- Provide an access for inspection and cleaning the
exhaust system at least once a year, especially at the
turns.
REAR EXHAUST LOCATION
The dryers come ready for rear exhausting. Units have
separate exhausts.

EXHAUST LENGTH
The MAXIMUM ALLOWABLE length of the exhaust sys-
tem depends upon the type of duct, number of turns, the
type of exhaust hood (wall cap),
and aII conditions noted below
The maximum allowable length
for both rigid and flexible metal
duct is shown in the table below.
More than two 90_'turns is not
recommended.
PREFERRED
4 in_ 2 '/in.
EXHAUST SYSTEM CHECK LIST
HOOD OR WALL CAP
. Terminate in a manner to prevent back drafts or entry of
birds or other wildlife
• Termination should present minimal resistance to the
exhaust air flow and should require littie or no mainte-
nance to prevent clogging
° Walt caps must be installed at least 12" above ground
level or any other obstruction with the opening pointed
down,
• If roof vents or Iouvered plenums are used, they must be
equivalent to a 4" dampered wall cap in regard to resis-
tance to air flow, prevention of back drafts and mainte-
nance required to prevent clogging,
SEPARATION OF TURNS
Separate all turns by at least 3 ft. of straight duct, includ-
ing distance between last turn and dampered wall cap_ if
two turns must be closer than 3 ft,, deduct 10 fL from the
maximum lengths shown in the table for each occurrence,
TURNS OTHER THAN 90 _
• One turn of 45'-' or less may be ignored
• Two 45" turns should be treated as one 90,
• Each turn over 45: should be treated as one 90'-'.
SEALING OF JOINTS
• All joints should be tight to avoid leaks The male end of
each section of duct must point away from the dryer.
° Do not assembte the duct work with fasteners that
extend into the duct. They willserve as a collection point
for lint.
o Duct joints can be made air and moisture-tight by wrap-
ping the overlapped joints with duct tape,
INSULATION
Duct work which runs through an unheated area or is
near an air conditioning duct should be insulated to
reduce condensation and lint build up and be sloped
down toward outdoors.
NOTE: Never install screen inside exhaust duct.
