9 Even though a 12-inch clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately 2 feet away from the nearest obstruction, i.e., wall, for ease of installation, maintenance, and service. 1. Leveling The Dryer T o increase bearing life, improve efficiency , and provide for better automatic closure of main doo[...]

10 D. Fresh Air Supply Air supply (make-up air) must be given careful consideration to assure proper and safe performance of each dryer . An unrestricted source of air of 550 cfm is necessary for each tumbler . An unrestricted air entrace from the outdoors (atmosphere) of a minimum of 2 square feet is required for each dryer . This area must be enl[...]

11 E. Exhaust Requirements General Information Exhaust duct work should be designed and installed by a competent technician. Improperly sized duct work will create excessive back pressure which results in slow drying, increased use of energy , and shutdown of the burner by airflow (sail) switch, burner hi-limit, or lint chamber hi-heat protector th[...]

12 IMPOR T ANT : Exhaust back pressure measured by a manometer at the dryer exhaust duct area must not exceed 0.3 inches of water column. NOTE : Careful consideration should be given to where the exhaust duct is located in relation to the make-up air openings. If make-up air opening is too close to exhaust outlet, lint and fumes will be drawn back [...]

13 The illustration below shows the duct work connection points and what internal duct work is included in the dryer . The exhaust connection at the TOP basket (tumbler) must be made at the blower duct inside the cabinet. No internal duct work is included for the TOP basket/tumbler . (Not available from ADC and must be purchased elsewhere). Dependi[...]

14 a. Connecting Both T op Baskets (T umbler) and Bottom Baskets (T umbler) T ogether Both the top basket (tumbler) and the bottom basket (tumbler) can “Y” together to form one connection point. The bottom basket (tumbler) already includes 6-inch diameter ducting extending to the lower back guard area. The minimum connection at this point is 8 [...]

15 2. Single Dryer V enting Where possible, it is suggested that a separate exhaust duct be provided for each dryer . The exhaust duct work 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 ducting be avoided; use 30º or 4[...]

16[...]

17 b. Single Dryer V enting - with common (top basket [tumbler] and bottom basket [tumbler] connected together) exhaust connections . If the top and bottom baskets (tumblers) connect or “Y” together as noted is Section E1 , the minimum diameter size at the “Y” or point of connections is 10 inches in diameter (80 square inches cross-sectiona[...]

18 The main common duct may be any shape so long as the minimum cross-sectional area is provided. The main duct should be tapered with the diameter increasing before each individual duct is added as per the illustration [MAN2172] on page 19 and the illustration [MAN2171] on page 20. The maximum length of venting from the last dryer to where it exha[...]

19 NOTE : The distance between the dryer single ducts being connected to the main common duct must be a minimum of 31-1/2 inches (the dryers width). NOTE : The duct work should be laid out in such a manner where allowances are made at the rear area of the dryer for removal of rear service panels/guards. IMPOR T ANT : Individual ducts being added to[...]

20 These figures must be increased in proportion if the main duct run from the last dryer has numerous elbows or is unusually long. For extended runs or where more elbows are added, the cross-sectional area of the duct can only be increased to an extent and a professional HV AC firm should be consulted for proper venting information. IMPOR T ANT : [...]

21 IMPOR T ANT : No more then four (4) dryers (eight [8] baskets [tumblers]) can be connected to one (1) common duct (vent). NOTE : The distance between the dryer single ducts being connected to the main common duct must be a minimum of 31-1/2 inches (the dryers width). The duct work should be laid out in such a manner where allowances are made at [...]

22 Important V enting Reminders 1. Duct work sizing and installation should be done by a qualified professional. 2. The dryer must be vented to the outdoors. 3. The duct work should be routed as short as possible to the outdoors with as few turns as possible. 4. A void 90º turns...use 30º or 45º turns instead. 5. The size (cross-sectional area) [...]
