Pre-Installation Requirements
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:
Correct Incorrect
Install male fittings in correct direction:
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 1.0 inch of water
column. If the system back pressure is
less than 1.0 inch of water column, the
system is acceptable. If the manometer
reading is higher than 1.0 inch of water
column, the system is too restrictive and
the installation is unacceptable.
Although vertical orientation of the
exhaust system is acceptable, certain
extenuating circumstances could affect the
performance of the dryer:
• Only the rigid metal duct work should
be used.
• Venting vertically through a roof may
expose the exhaust system to down
drafts causing an increase in vent
restriction.
Manufactured or mobile
home installation
1. Installation MUST conform to current
Manufactured Home Construction &
Safety Standard, Title 24 CFR, Part
32-80 (formerly the Federal Standard for
Mobile Home Construction and Safety
for Mobile Homes, Title 24, HUD Part
280) or Standard CAN/CSAZ240 MH.
2. Dryer MUST be exhausted outside
(outdoors, not beneath the mobile
home) using metal ducting that will
not support combustion. Metal ducting
must be 4 inches (10.16 cm) in
diameter with no obstructions. Rigid
metal duct is preferred.
3. If dryer is exhausted through the floor
and area beneath the mobile home is
enclosed, the exhaust system MUST
terminate outside the enclosure with
the termination securely fastened to a
non-combustible portion of the mobile
home structure.
4. Refer to previous sections in this guide
for other important exhaust venting
system requirements.
5. When installing a gas dryer into a
mobile home, a provision must be made
for outside make up air. This provision is
to be not less than twice the area of the
dryer exhaust outlet.
6. Installer MUST anchor this (1) dryer
or (2) dryer mounted on pedestal to
the floor with approved Mobile Home
Installation Kit - P/N 137067200.
WARNING
FIRE 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.
NOTE
Use of 90° quick-
turn elbow required
to meet minimum installation depth.
• Running the exhaust system through
an uninsulated area may cause
condensation and faster accumulation
of lint.
• Compression or crimping of the exhaust
system will cause an increase in vent
restriction.
• The exhaust system should be
inspected and cleaned a minimum
of every 18 months with normal
usage. The more the dryer is used,
the more often you should check the
exhaust system and vent hood for
proper operation and that it is free of
obstructions.
