SECTION III INSTALLATION PROCEDURES Installation should be performed by competent technicians in accordance with local and state codes. In the absence of these codes, the installation must conform to applicable American National Standards: ANSI Z223.1- LATEST EDITION (National Fuel Gas Code) or ANSI/NFPA NO. 70-LATEST EDITION (National Electrical Code) or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST EDITION (for General Installation and Gas Plumbing) or Canadian Electrical Codes Parts 1 &... -
Page 13: Unpacking/Setting Up
IMPORTANT: Dryer should be located where a minimum amount of exhaust duct will be necessary. IMPORTANT: Dryer must be installed in a location/environment, which the ambient temperature remains between 40° F (4.44° C) and 130° F (54.44° C). B. UNPACKING/SETTING UP Remove protective shipping material (i.e., plastic wrap and/or optional shipping box) from dryer. -
Page 14: Fresh Air Supply Requirements
NOTE: Allowances must be made for the opening of the control door. Dryers may be positioned sidewall to sidewall. However, a 1/16” (1.58 mm) minimum allowance must be made for the opening and closing of the control door. It is suggested that the dryer be positioned about 2 feet (0.61 meters) away from the nearest obstruction for ease of installation, maintenance, and service (to be measured from the back guard). -
Page 15: Exhaust Requirements
To compensate for the use of registers or louvers used over the openings, these make-up air openings 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. - Page 16 CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN CREATE A POTENTIAL FIRE HAZARD. The 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. Single or independent dryer venting is recommended. Horizontal Venting: When single dryer venting is used, the length of ductwork from the dryer to the outside exhaust outlet must not exceed 25 feet (7.62 meters).
- Page 17 2. Single Dryer Venting When 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 ductwork travels as directly as possible to the outdoors with as few turns as possible.
- Page 18 IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be increased to an extent. When the ductwork approaches the maximum limits noted in this manual, a professional heating, ventilating, and air-conditioning (HVAC) firm should be consulted for proper venting information. IMPORTANT: DO NOT use screens, louvers, or caps on the outside opening of the exhaust ductwork.
