IMPORTANT: Even though a minimum of only 12 inches is required, 18 inches or more is suggested, especially in cases where sprinkler heads are over the installation and service. IMPORTANT: When fire sprinkler systems are located above the dryers, a minium of 18 inches above the dryer console (module) is required. Dryers may be positioned side wall to side wall however, a 1/16” minimum allowance is required between dryers (or wall) for base of installation and maintenance. Allowances must be mad

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 of the dryers. EXAMP

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 ex

2. Single Dryer Venting Where possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust duct should be laid out in such a way that the duct work travels as directly as possible to the outdoors with as few turns as possible. It is suggested that the use of 90º turns in the ducting be avoided; use 30º or 45º angles instead. The shape of the exhaust duct work is not critical so long as the minimum cross section area is provided. IMPORTANT: Minimum duct size for dry

It is important that the duct work from each dryer not exceed fifteen (15) feet with no more than (2) elbows (excluding dryer connections and outside exhaust outlets). If the duct work exceeds fifteen (15) feet or has numerous elbows, the cross section area of the duct work must be increased in proportion to the length and number of elbows in it. In calculating duct size, the cross section area of a square or rectangular duct must be increased by twenty (20) percent for each additional fifteen
