D. FRESH AIR SUPPLY When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the make-up air is inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and sail switch "fluttering" problems may result, as well as premature motor failure from overheating.
E. EXHAUST REQUIREMENTS 1. General Exhaust Duct Work Information 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: DRYER MUST BE EXHAUSTED TO THE OUTDOORS.
NOTE: Where 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 (all the way around) than the duct. The duct must be centered within this opening. a. Outside Duct Work Protection 1) To protect the outside end of horizontal duct work from the weather, a 90° elbow bent downward should be installed where the exhaust exits the building.
IMPORTANT: For extended duct work runs, the cross section area of the duct work can only be increased to an extent. When the duct work approaches the maximum limits noted in this manual, a professional heating venting air conditioning (HVAC) firm should be consulted for proper venting information. ALL duct work should be smooth inside with no projections from sheet metal screws or other obstructions which will collect lint.
3. Multiple (common) Dryer Venting IMPORTANT: For extended duct work runs, the cross section area of the duct work can only be increased to an extent.
