14 PRE-INSTALLATION REQUIREMENTS WARNING FIRE HAZARD • Failure to follow safety warnings exactly could result in serious injury, death, or property damage. • DO NOT install a booster fan in dryer exhaust duct. • Install all clothes dryers in accordance with the installation instructions in this manual. Install male fittings in correct direction: • Venting vertically through a roof may expose the exhaust system to down drafts causing an increase in vent restriction. • Running the exhaust system through an uninsulated area may cause condensation and faster accumulation of lint. • Compression or crimping of the exhaust system will cause an increase in vent restriction. • The exhaust system should be inspected and cleaned a minimum of every 18 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. Correct Incorrect Rear flush exhaust requirements The laundry center may be exhausted four (4) ways with rear flush installation: In installations where the exhaust system is not described in the charts, the following method must be used to determine if the exhaust system is acceptable: 1. Connect an inclined or digital manometer between the dryer and the point the exhaust connects to the dryer. 2. Set the dryer timer and temperature to air fluff (cool down) and start the dryer. 1. Straight back 2. Down (8 inch [20.3 cm] length of 4 inch diameter [102 mm] rigid duct and 1 elbow down) 3. Left (8 inch [20.3 cm] length of 4 inch diameter [102 mm] rigid duct, 1 elbow down and 1 elbow left) 4. Right (8 inch [20.3 cm] length of 4 inch diameter [102 mm] rigid duct, 1 elbow down and 1 elbow right) 3. Read the measurement on the manometer. 4. The system backpressure MUST NOT be higher than 0.6 inches of water column. If the system back pressure is less than 0.6 inches of water column, the system is acceptable. If the manometer reading is higher than 0.6 inches of water column, the system is too restrictive and the installation is unacceptable. Although vertical orientation of the exhaust system is acceptable, certain extenuating circumstances could affect the performance of the dryer: • Only rigid metal duct work should be used.
