IMPORTANT: Make-up air openings should not be located near duct work exhaust outlets. If make-up air opening(s) are too close to the exhaust outlet, lint and fumes may be drawn back into the dryer area through these openings. NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
E. EXHAUST REQUIREMENTS Exhaust duct work should be designed and installed by a qualified professional. Improperly sized duct work will create excessive back pressure which results in slow drying, increased use of energy, overheating of the dryer, and shutdown of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-heat thermostats. CAUTION: IMPROPERLY SIZED or INSTALLED EXHAUST DUCT WORK CAN CREATE A POTENTIAL FIRE HAZARD.
NOTE: When the exhaust duct work passes through a wall, ceiling, or roof made of combustible materials, the opening must be 2-inches (5.08 cm) larger than the duct (ALL the way around). The duct must be centered within this opening. To protect the outside end of the horizontal duct work from the weather, a 90º elbow bent downward should be installed where the exhaust exits the building.
2. Multiple Dryer (common) Venting If it is not feasible to provide separate exhaust ducts for each dryer, ducts from individual dryers may be channeled into a “common main duct.” The individual ducts should enter the bottom or side of the main duct at an angle not more than 45º in the direction of the airflow. The main duct should be tapered, with the diameter increasing before each individual 8-inch (20.32 cm) duct is added.
IMPORTANT: DO NOT use screens or caps on the outside opening of the exhaust duct work.
