Exhaust direction
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 hardware store.
Exhaust system requirements, continued
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 fl uff (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 .075
inches 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.
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.
Manufactured or mobile home installation
Installation MUST conform to current Manufactured
1.
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 CAN/CSAZ240 MH.
Dryer MUST be exhausted outside (outdoors, not beneath
2.
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 fl oor and area beneath
3.
the mobile home is enclosed, 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
4.
exhaust venting system requirements.
When installing a gas dryer into a mobile home, a
5.
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
6.
on pedestal to the fl oor with approved Mobile Home
Installation Kit - P/N 137067200.

Use of 90° quick-turn elbow required to meet mini-
mum installation depth of free-standing dryer:
Straight back venting allows for 0” (0 cm) installation.
•
Venting right with 90° elbow allows for 0.75” (2 cm)
•
installation.
Venting downward with 90° elbow allows for 0.75” (2 cm)
•
installation.
Venting left with short, straight adapter and 90° elbow
•
allows for 3.75” (9.5 cm) installation.
Venting upward with short, straight adapter and 90°
•
elbow allows for 4” (10.5 cm) installation.
