10 9. The dryer must be installed with a proper exhaust duct connection to the outside. 10 . The dryer must be installed with provisions for adequate combustion and make-up air supply . CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6 months, inspect the exhaust ducting and remove any lint build up. IMPOR[...]

11 IMPOR T ANT : Make-up air must be provided from a source free of dry cleaning solvent fumes. Make-up air that is contaminated by dry cleaning solvent fumes will result in irreparable damage to the motors and other dryer components. IMPOR T ANT : Make-up air openings should not be located near ductwork exhaust outlets. If the make-up air opening([...]

12 E. EXHAUST REQUIREMENTS 1. General Exhaust Ductwork Information Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork 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, [...]

13 IMPOR T ANT : Exhaust back pressure measured by a manometer at the dryer exhaust duct area must be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water column (W .C.).

19 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 illustrations on page 20 and page 21 . The maximum length of venting from the last dryer to where it exhausts is the following: VER TICAL - ven[...]

20 NOTE: The distance between the dryer single ducts being connected to the main common duct must be a minimum of 31-1/2” (80.01 cm) dryer ’ s width.

IMPOR T ANT : Individual ducts being added[...]

21 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 heating, venting, and air conditioning (HV AC) firm should be consulted for p[...]

22 IMPOR T ANT : No more than 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” (80.01 cm) dryer ’ s width. The ductwork should be laid out in such a manner where allowances are made a[...]

23 IMPOR T ANT VENTING REMINDERS 1. Ductwork sizing and installation should be done by a qualified professional. 2. The dryer must be vented to the outdoors. 3. The ductwork 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) of[...]
