For further details, consult this publication, or the current edition available from National Fire Protection Association, Inc., Batterymarch Park, Quincy, MA 02269, or American Gas Association, 1515 Wilson Boulevard, Arlington, VA 22209. These instructions cover minimum requirements and conform to existing national standards and safety codes In some instances, these instructions exceed certain local codes and ordinances, especially those that may not have kept pace with changing residential construction practices. Carrier requires these standard procedures as a minimum for a safe installation. Refer also to regulations of the local gas supplier as well as to local building, heating, plumbing, or other codes in effect in area in which installation is made. A WARNING LOCATION OF FURNACE AND AIR FOR VENTILATION Locate the furnace as near the center of the air distribution system as possible. Provide ample space for servicing and cleaning. Always comply with the minimum fire protection clearances shown on the unit rating plate This furnace must NOT be installed directly on carpeting, tile, or any combustible material other than wood flooring. A CAUTION Do not install furnace in unconditioned space that could experience temperatures of 32 F or lower. NOTE: For proper furnace operation, the furnace must be installed within 1/2 in of level. When furnace supply ducts deliver air to areas outside the space containing the furnace, return air ducts must also be sealed to furnace casing and must terminate outside the space containing the furnace. Otherwise, a negative pressure condition could develop within equipment room or space Never store items such as the following on, near, or in contact with the furnace 1. Spray or aerosol cans, rags, brooms, dust mops, vacuum cleaners, or other cleaning tools. 2. Soap powders, bleaches, waxes or other cleaning compounds; plastic items or containers; gasoline, kerosene, cigarette lighter fluid, dry-cleaning fluids, or other volatile fluids. 3 Paint thinners and other painting compounds. 4. Paper bags or other paper products. Furnace Location Relative to Cooling Equipment — Install cooling coil in parallel with, or on downstream side of, furnace to reduce potential for condensation in heat exchanger. When a coil is installed in parallel with a furnace, dampers or other means used to control airflow must prevent chilled air from entering furnace. For manual damper operation, equip dampers with a means of preventing operation of either unit unless damper is in the full-heat or full-cool position.

Special Locations — When installing furnace in a iesidential garage, protect it from physical damage by vehicles. Furnaces installed in public garages, airplane hangars, or other buildings having hazardous atmospheres must comply with requirements of the National Fire Protection Association, Inc. Ventilation Air — Requirements depend upon whether the furnace is located in an “unconfined” or “confined” space: Unconfined space — A space whose volume is not less than 50 cu ft/1000 Btuh of the total input rating of all appliances installed in the space Rooms are considered a part of the unconfined space when they communicate through openings not furnished with doors with the space in which the appliances are installed. No special ventilating means are required for furnaces installed in unconfined spaces Confined space — A space whose volume is less than 50 cu ft/1000 Btuh of the total input ratings of all appliances installed in that space. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations. Book 11 PC 101 Catalog No 515-806 Printed in U S.A Form 58SX-3XA Pg 1 2-85 Replaces: New Tab |6a For casing ventilation purposes, provide the confined space with 2 permanent openings, one within 12 in. of top and one within 12 in. of bottom of enclosure. Each opening shall have a minimum free area of one sq in / 1000 Btuh of total input rating of all equipment in enclosure, but not less than 100 sq inches Openings must freely communicate with interior areas whose volume, when combined with the volume of the confined space, meet the criteria for an unconfined space. This can be accomplished through installation of either permanent openings or louvered doors. LOUVERS AND GRILLES — When calculating the free ...
