E. EXHAUST REQUIREMENTS
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 shut down of the burner by the airflow (sail) switches, burner
CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN CREATE A POTENTIAL FIRE HAZARD.
The exhaust ductwork should be laid out in such a way that the ductwork travels as directly as possible to the outdoors with as few turns as possible. When single dryer
It is suggested that the use of 90º turns in ducting be avoided; use 30º or 45º angles instead. Excluding basket (tumbler)/dryer elbow connections or elbows used for outside protection from the weather, no more than two (2) elbows should be used in the exhaust duct run. If more than two (2) elbows are used, the cross section area of the ductwork must be increased in proportion to the number of elbows added.
1.Exhaust Connections of Top and Bottom Baskets (Tumblers)
There is no common venting connection provided with the dryer. Each basket (tumbler) exhaust duct is provided with its own back draft damper. Each basket (tumbler) can be exhausted directly outdoors independently or connected to a common duct. Both single and common ductwork can be rigid ducting or flexible ducting. For common connections, a kit (P/N 882035) is available from the factory and includes the necessary flex ducting, elbows, and “Y” assembly, etc., to join the top and bottom exhausts together.
ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building.
IMPORTANT: Exhaust back pressure measured by a manometer at each basket (tumbler) exhaust duct area must be no less than 0 and must not exceed 0.3 inches (0.74 mb) water column (W.C.) when both baskets (tumblers) are operating.
NOTE: Common exhaust connections of top and bottom baskets (tumblers) should be installed in such a manner that the back guards can be removed easily for servicing.
IMPORTANT: It is recommended that exhaust or booster fans NOT BE USED in the exhaust ductwork system.
NOTE: As per the National Fuel Gas Code, “Exhaust ducts for Type 2 clothes dryers shall be constructed of sheet metal or other noncombustible material. Such ducts shall be equivalent in strength and corrosion resistance to ducts made of galvanized sheet steel not less than 26 gauge
