Standard exhaust installation with rigid metal or flexible metal vent Determine Vent Length 1. Select the route that will provide the straightest and most direct path outdoors. Plan the installation to use the fewest number of elbows and turns. When using elbows or making turns, allow as much room as possible. Bend vent gradually to avoid kinking. Avoid 90º turns. Alternate installations for close clearances Venting systems come in many varieties. Select the type best for your installation. Two close-clearance installations are shown. Refer to the manufacturer's instructions. 2. Determine vent length The maximum length of the exhaust system depends upon: s The type of vent (rigid metal or flexible metal). s The number of elbows used. s Type of hood. Recommended hood styles are shown here. 2 1 1 2 1. Over-The-Top installation (also available with one offset elbow) 2.

Determine the number of elbows you will need. NOTE: Do not use vent runs longer than specified in the Vent Length Chart. The following chart helps you determine your maximum vent length based on the number of 90° turns or elbows you will need and the type of vent (rigid or flexible metal) and hood that you will use. Terminate the exhaust vent outside. The exhaust vent must not terminate beneath the mobile home and must not be connected to any other duct, vent or chimney. 9
