Installation Instructions WARNING USE ONLY METAL DUCT 4″ DIAMETER (102 mm FOR CANADA). DO NOT USE DUCT LONGER THAN SPECIFIED IN THE EXHAUST LENGTH TABLE. Dryer Exhausting Information-Metal Duct Only Ducting Materials: For best performance, this dryer should be vented with 4″ diameter all-rigid metal exhaust duct. Exhaust Length Calculation: 1. Determine the number of 90º turns needed for your installation. 2. The maximum length of 4′ rigid (aluminum or galvanized) duct which can be tolerated is shown in the table. A turn of 45º or less may be ignored. Two 45º turns within the duct length should be treated as a 90º elbow. A turn over 45º should be treated as a 90º elbow. CAUTION: For personal safety, do not terminate exhaust into a chimney, under any enclosed house floor (crawl space), or into an attic, since the accumulated lint could create a fire hazard or moisture could cause damage. Never terminate the exhaust into a common duct or plenum with a kitchen exhaust, since the combination of lint and grease could create a fire hazard. Exhaust ducts should be terminated in a dampered wall cap to prevent back drafts, bird nesting, etc. The wall cap must also be located at least 12″ above the ground or any other obstruction with the opening pointed down. Other terminations, such as louvered wall boxes, are acceptable provided they are equivalent to a 4″ opening dampered wall cap.
