VENTING THE DRYER

CHECK YOUR EXHAUST SYSTEM FOR

PROBLEMS

The most common cause of dryer problems is poor exhaust venting. Before you install 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 efficiency.

ODIRTY 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.

O WRONG VENT MATERIAL. Check your vent to make sure it is rigid or semi-rigid metal ducting. If your venting is plastic or flexible foil, have it replace before using the dryer.

O RESTRICTED OR DAMAGED VENT HOOD. Check your vent hood outside. It must be clean and free of lint buildup. Check the damper and make sure it opens fully and easily.

O EXESSlVELY LONG VENT. Measure the length of your exhaust system and count the elbows. Use the chart below 14 to see if your duct is too long. If it is too long, have the duct routed to another location that is within the venting guidelines.

ODO NOT USE PLASTIC OR FOIL VENTING. The transition duct from your dryer to the wall must be rigid or semi-rigid metal ducting. If your old transition duct is plastic or foil, REPLACE IT with semi-rigid metal ducting.

Using the Duct Requirements Chart (below)

0Select the type of vent hood.

0Select the row that matches the number of elbows in the dryer duct run.

0Look to the right of elbow number for the maximum duct length for your installation. Duct lengths longer than shown will result in reduced drying performance, longer dry times and increased energy consumption.

DO NOT exceed maximum length for the hood type and number of elbows used.
