INSTALLATION INSTRUCTIONS

VENTING THE DRYER

IMPORTANT! 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 efficiency.

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 ducting. If your venting is plastic or flexible foil, have it replaced before using the dryer.

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.

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 long. If it is too long, have the duct routed to another location that is within the venting guidelines.

DO 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 LENGTH CHART (below)

1Find your vent hood type in the chart below.

2Select the row that matches the number of elbows in your dryer duct run.

3Look 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 shorten the life of the dryer.

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