Drain Requirements; Exhaust System Requirements - Kenmore 7972 - 700 7.5 cu. Ft. Capacity Gas Dryer Installation Instructions Manual

DRAIN REQUIREMENTS
1. Drain capable of eliminating 17 gals. per minute.
2. A standpipe diameter of 1¼ inches (3.18 cm) minimum.
3. The standpipe height above the floor should be:
Minimum height: 33 inches (83.82 cm)
Maximum height: 96 inches (244 cm)
--T--
33" Min.
(83.82cm)

(244 cm)
NOTE: For installations requiring a longer drain hose, have a qualified
technician install a longer hose, PIN 134049201, available from an
authorized parts distributor. For drain systems in the floor, install a
siphon break kit, available from your local hardware store.
EXHAUST SYSTEM REQUIREMENTS
Use only 4 inch (10.16 cm) diameter (minimum) rigid or flexible
metal duct and approved vent hood which has a swing-out
damper(s) that opens when the dryer is in operation. When the
dryer stops, the damper(s) automatically closes to prevent drafts
and the entrance of insects and rodents. To avoid restricting the
outlet, maintain a minimum of 12 inches (38,5 cm) clearance
between the vent hood and the ground or any other
obstruction.
The following are specific requirements for proper
and safe operation of your laundry center. Failure to follow these
instructions can create excessive drying times and fire hazards.
Do not use plastic flexible duct or metal foil to
exhaust the dryer. Excessive lint can build up inside the exhaust
system and create a fire hazard and restrict air flow. Restricted air
flow will increase drying times. If your present system is made up of
plastic duct or metal foil duct, _lace it with a rigid or flexible metal
d uct. Ensure the present duct is free of any lint prior to installing
laundry center dryer duct.
If the dryer is not exhausted outdoors some fine
lint will be expelled into the laundry area. An accumulation of lint in
any area of the home can create a health and fire hazard. The dryer
exhaust system MUST be exhausted to the outside of the
dwelling!
Do not allow combustible materials (for example:
clothing,draperies/curtains, paper) to come in contact with the
exhaust system. The dryer MUST NOT be exhausted into a chimney,
a wall, a ceiling, or any concealed space of a building which can
accumulate lint, resulting in a fire hazard.
Do not exceed the length of duct pipe or number of
elbows allowed in the" EXHAUST DUCT LENGTHS" chart. Lint can
accumulate in the system, plugging the system and creating a fire
hazard, as well as increasing drying times.
_Do not the exhaust ends of the vent
screen
system,
nor use any screws or rivets to assemble the exhaust system. Lint can
become caught in the screen, on the screws or rivets, clogging the
exhaust system and creating a fire hazard as well as increasing drying
times. Use an approved vent hood to terminate the duct outdoors,
and seal all joints with duct tape. All male duct pipe fittings MUST
be installed downstream with the flow of air. 3
Explosion hazard, Do not install the laundry center
where gasoline or other flammables are kept or stored.If the laundry
center is installed in a garage, it must be a minimum of 18 inches
(45.7 cm) above the floor. Failure to do so can result in death, explosion,
fire or burns. The exhaust system back pressure MUST not exceed
0.6 inches (1.52 cm) of water column, measured with an inclined
manometer at the point the exhaust connects to the dryer. The
exhaust system should be inspected and cleaned a minimum of
every two years with normal usage. The more the dryer is used, the
more often you should check the exhaust system and vent hood for
proper operation.
The maximum length of the exhaust system depends upon the type
of duct used, number of elbows and type of exhaust hood.
The maximum length for both rigid and flexible duct is shown in the
chart below.

The laundry center may be exhausted four (4) ways with rear flush
installation:
1. Straight back
2. Down (8 inch [20.32 cm] length of 4 inch [10.16 cm] rigid duct
and 1 elbow down)
3. Left (8 inch [20.32 cm] length of 4 inch [10.16 cm] rigid duct, 1
elbowdown and 1 elbow left)
4. Right (8 inch [20.32 cm] length of 4 inch [10.16 cm] rigid duct, 1
elbowdown and 1 elbow right)
To exhaust up, add an 11 inch (27.94 cm) length of standard 4 inch
(10.16 cm) diameter duct and a 90 ° elbow. The unit will be positioned
about 41/2 inches (11.43 cm) away from the wall (flush to wall
exhausting may be done by going below the dryer then sideways).
An exhaust hood positioned to line up with the dryer exhaust can be
installed directly through the outside wall. To exhaust to the side or
down, add an 8 inch (20.32 cm) length of standard 4 inch (10.16 cm)
diameter duct and a 90 ° elbow.
