Anleitung Zusammenfassung
Homes are now tighter, resulting in less natural air infiltration and inefficient furnace operation. The condition is further affected by the growing use of kitchen and bathroom exhausts and even fireplaces. Field studies indicate that combustion air starvation, particularly in closet installations, points to a need for positive furnace air supply, plus new guidelines for today’s furnace applications. A WARNING These instructions cover minimum combustion air requirements and venting practices. They also reflect current conditions found in the field, 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 construction practices. Carrier requires these standard procedures as a minimum for safe installation. A CAUTION Do not block openings in front of furnace or on furnace top along side vent pipe. These openings provide air for combustion and ventilation. Never store anything on or in contact with furnace, such as: aerosol cans, rags, brooms and mops, cleaning tools and aids, powders, bleaches, waxes, plastic items, gasoline, kerosene, lighter fluids, cleaning fluids, thinners, painting compounds or paper products. Installation Procedures — These recommendations apply to the installation and operation of gas furnaces and piping systems for natural or LP (propane) gases. Use these procedures in conjunction with your specific furnace installation instructions. Refer also to your gas supplier regulations and local building, heating, plumbing and other codes for your installation area. Portions of the following have been adopted in part from the National Fuel Gas Code (NFPA No. 54-1984 or ANSI Z223.1-1984) copyrighted by the National Fire Protection Association and American Gas Association.

Check available gas supply to see that it conforms to gas specifications on AGA rating plate. FURNACE LOCATION — COMBUSTION/VENTILATION AIR Locate furnace close to chimney and as near to the center of the air distribution system as possible. Install furnace as level as possible. Provide ample space for servicing and cleaning. Always comply with minimum fire protection clearances shown on unit rating plate. Do not install directly on carpeting, tile or any combustible material other than wood flooring. Accessory combustible floor base is available from your dealer when required. The relief-air supply for the draft safeguard duct (draft hood) must be in the same atmospheric pressure zone as the combustion-air inlet supply to the furnace. When a furnace is installed so that the supply ducts carry air to areas outside the space containing the furnace, the return air must also be handled by duct(s) sealed to the furnace casing and terminating outside the furnace location area. All fuel-burning furnaces must be supplied with air that enters the combustion process and then is vented to the outdoors. Sufficient air must enter the space containing the furnace to replace the amount drawn up the vent stack. Replacement air must be provided by means of ducts from the outside to the furnace area or heated space. Under all conditions, enough air must be provided to ensure there will be no negative pressure condition Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

A positive seal must be made between the furnace base and platform or return-air duct connections. Even a slight leak can create a negative pressure condition in a confined closet or basement and affect combustion. If necessary, seal the furnace base-to-floor opening with fiberglass or other approved material. Furnaces with side-connected...
