VENTINGTHEDeYER
|MPORTANT! CHECK YOUR EXHAUST SYSTEM FOR PROBLEMS
The most common cause of dryer problems is poor *
exhaust venting. Before installing your new dryer,
check the items listed below to make sure you get the
best possible performance. This can save you time and
money by reducing cycle times and increasing energy •
e{_)ciency.
• DIRTY OR DAMAGED EXHAUST DUCTS. Lint builds
up in exhaust ducts over time. This decreases the
airflow and makes the dryer work harder. Visually
inspect your ducts from both ends and have them
cleaned if they have not been cleaned recently.
* WRONG VENT MATERIAL. Check your vent to make
sure it is rigid or semi-rigid metal ducfing, if your
venting is plastic or flexible foil, have if replaced
before ushg the dryer.
RESTRICTED OR DAMAGED VENT HOOD. Check
your vent hood outside. !t must be clean and free of lint
buildup. Check the damper and make sure it opens fully
and easily.
EXCESSIVELY LONG VENT. Measure the length of your
exhaust system and count the elbows. Use the chart
below to see if your duct is too (ong. If it is fad (one,
have the duct routed to another mocafion that is within
the venting guidelines.
o DO NOT USE PLASTIC OR FOIL VENTING. The
transition duct from your dryer to the waft must be rigid
or semi-rigid metal ducfing. If your old transition duct is
plastic or foil_ REPLACE IT with semi-rigid metal ducting.
Using the DUCT LENGTH CHART (be|ow)
0 Find ycur vent hood type in the chart below.
Select the row that matches the number of elbows in your dryer duct run.
Look to the right of the elbow number for the maximum duct length for your installation. Longer duct length will result
in reduced drying performance, longer dry times and increased energy consumption. Extremely long ducts can even
shortenthe life of the dryer.
DO NOT exceed the maximum length for the vent hood type and number of elbows used.
