Exhaust system requirements, continued
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.
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.
Running the exhaust system through an
uninsulated area may cause condensation and
faster accumulation of lint.
Manufactured or mobile home installation
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, Title 24, HUD Part 280) or Standard
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.
If dryer is exhausted through the floor and
area beneath the mobile home is enclosed,
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.
Directional exhausting can be accomplished by
installing a quick-turn 90° dryer vent elbow directly
to exhaust outlet of dryer. Dryer vent elbows are
available through your local parts distributor or
See also CLEARANCE REQUIREMENTS on the
Use of 90° quick-turn elbow required to meet
minimum installation depth.
the exhaust system MUST terminate outside
the enclosure with the termination securely
fastened to the mobile home structure.
Refer to previous sections in this guide for other
important exhaust venting system requirements.
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.
Installer MUST anchor this (1) dryer or (2) dryer
mounted on pedestal to the floor with approved
Mobile Home Installation Kit - P/N 137067200.
