Exhaust System Requirements - Frigidaire FEQ1442CES0 Installation Instructions Manual

EXHAUST SYSTEM REQUIREMENTS

Use only 4 inch (10.2 cm) diameter (minimum) rigid or
flexible metal duct and approved vent hood which has a
swing-out damper(s) that open when the dryer is in
operation. When the dryer stops, the dampers automatically
close to prevent drafts and the entrance of insects and
rodents. To avoid restricting the outlet, maintain a minimum
of 12 inches (30.5 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 dryer. Failure to
follow these instructions can create excessive drying
times and fire hazards.
Do not use plastic flexible duct to exhaust
the dryer. Excessive lint can build up inside exhaust system
and create a fire hazard and restrict air flow. Restricted air
flow will increase dryer times. If your present system is made
up of plastic duct or metal foil duct, replace it with a rigid or
flexible metal duct. Ensure the present duct is free of any
lint prior to installing 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 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.
Exceeding the length of duct pipe or
number of elbows allowed in the "MAXIMUM LENGTH"
charts can cause an accumulation of lint in the exhaust
system. Plugging the system could create a fire hazard, as
well as increase drying times.
Do not screen the exhaust ends of the
vent 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 duct work 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.
Explosion hazard. Do not install the dryer
where gasoline or other flammables are kept or stored.
If the dryer 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.

INSTALL MALE FITTINGS IN CORRECT DIRECTION
In installations where the exhaust system is not described in
the charts, the following method must be used to
determine if the exhaust system is acceptable:
1. Connect an inclined or digital manometer between the
dryer and the point the exhaust connects to the dryer.
2. Set the dryer timer and temperature to air fluff (cool
down) and start the dryer.
3. Read the measurement on the manometer.
4. The system back pressure MUST NOT be higher than
0.75 inches of water column. If the system back
pressure is less than 0.75 inches of water column, the
system is acceptable. If the manometer reading is
higher than 0.75 inches of water column, the system is
too restrictive and the installation is unacceptable.
