English maintain a minimum of 12 inches (30.5cm) clearance between the vent hood and the ground or any other obstruction. The vent flap should be able to move freely, although vertical orientation of the exhaust system is acceptable. Certain extenuating circumstances could affect the performance of the dryer: 1. Only rigid or flexible metal duct work should be used. 2. Venting vertically through a roof may expose the exhaust system to down drafts causing an increase in vent restriction. 3. Running the exhaust system through an uninsulatedarea may cause condensation and faster accumulation of lint. 4. Compression of crimping of the exhaust system will cause an increase in vent restriction. 5. In Canada, that only those foil-type flexible ducts, if any, specifically identified for use with the appliance by the manufacturer shall be used. In the United States, that only those foil-type flexible ducts, if any, specifically identified for use with the appliance by the manufacturer and that comply with the UL Outline for Clothes Dryer Transition Duct, Subject 2158A (2006), shall be used. 6. In Canada, that the exhaust duct shall be 102 mm in diameter. In the United States, the required exhaust duct diameter; 7. The total length of flexible metal duct shall not exceed 2.4 m. The exhaust system should be inspected and cleaned a minimum of every 12 months with normal usage. The more the dryer is used the more often you should check the exhaust system and vent hood for proper operation.
