Maytag MDG9800AWQ Installation - Manual (Page 4)

WARNING – plastic or nonmetal flexible duct presents a potential fire hazard.
NEVER USE PLASTIC OR NONMETAL FLEXIBLE DUCT.
If your existing ductwo rk is plastic, nonmetal or combu s t i bl e, replace it with metal. Use only metal
exhaust duct that will not support combustion to insure the containment of exhaust air, heat and lint.
EXHAUSTING
Exhausting the dryer to the outside will prevent large amounts of lint and moisture from being blown into the
room.
In the United States:
•all gas drye rs must be exhausted to the outside.
• electric drye rs located in a confined area such as a bedro o m , b a t h ro o m , or closet must be ex h a u s t-
ed to the outside.
• electric dryers not located in a confined area may be exhausted to the inside (see nonexhausted
installations).
In Canada:
• all gas and electric dryers must be exhausted to the outside.
Outside the U.S. and Canada:
• refer to local codes.
Plastic flex i ble duct can kink, sag, be punctured, reduce air
f l ow, extend drying times and affect dryer opera t i o n .
USE A MINIMUM OF 4-INCH (10.2 cm) DIAMETER
RIGID ALUMINUM OR RIGID GALVANIZED STEEL
DUCT. Do not use smaller duct. Ducts larger than
4 inches (10.2 cm) in diameter can result in increased
lint accumulation. Lint accumulation should be cleaned
regularly. If flexible metal duct must be used, use the
type with a stiff sheet metal wall. Do not use flexible
duct with a thin foil wall. Serious blockage can result if
flexible metal duct is bent too sharp. Never install any
type of flexible duct in walls, ceilings or other concealed
spaces.
Keep exhaust duct as straight and short as possibl e.
Exhaust systems longer than recommended can ex t e n d
d rying times, affect machine operation and may collect
l i n t . Secure joints with duct tape. Do not use screw s.
DO NOT EXHAUST DRYER INTO ANY WALL,
CEILING, CRAWL SPACE OR A CONCEALED SPACE
OF A BUILDING, GAS VENT, ANY OTHER COMMON
DUCT OR CHIMNEY. THIS COULD CREATE A FIRE
HAZARD FROM LINT EXPELLED BY THE DRYER.
The exhaust duct should end with an exhaust hood with a swing out damper to prevent backdrafts and entry
of wildlife. Never use an exhaust hood with a magnetic damper. The hood should have at least 12 inches
(30.5 cm) of clearance between the bottom of the hood and the ground or other obstruction. The hood
opening should point down. Never install a screen over the exhaust outlet.
When possible, do not exhaust the dryer directly into a window well in order to avoid lint build-up. Do not
exhaust under a house or porch.
