To compensate for the use of registers or louvers used over the openings, this make-up air must be increased by approximately thirty-three percent (33%). Make-up air openings should not be located in an area directly near where exhaust vents exit the building. It is not necessary to have a separate make-up air opening for each dryer. Common make-up air openings are acceptable. However, they must be set up in such a manner that the make-up air is distributed equally to ALL the dryers. EXAMPLE:

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. CAUTION: IMPROPERLY SIZED OR INSTALLED E

IMPORTANT: Minimum duct work diameter for horizontal venting is 10-inches and for vertical venting the minimum is 12-inches. NOTE: Where the exhaust duct work passes through a wall, ceiling, or roof made of combustible materials, the opening must be 2-inches 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
