Anleitung Zusammenfassung


Combustion air supply for gas-fired equipment can be affected by these construction conditions, because infiltration that existed in the past may not now be adequate. Extensive use of kitchen and bathroom exhaust fans, and even fireplaces, aggravates the situation. Today’s building practices invalidate the old rule of thumb of “one air change by infiltration.” Reliance on this practice can result in combustion air starvation if proper combustion air is not provided. In fact, recent field investigations, particularly with closet installation of gas-fired furnaces, indicate the need for positive provision for combustion air and for a better understanding of application guidelines that relate to today’s conditions. These instructions cover minimum combustion air requirements and venting practices, 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 the changing residential construction practices. Carrier requires these standard procedures as a minimum for a safe installation. CAUTION: Do not obstruct openings in front of the furnace or in the top on each side of the vent pipe. These provide air for combustion and ventilation. Never store anything on or in contact with the furnace such as: Spray or aerosol cans, rags, brooms, dust mops, vacuum cleaners, or other cleaning tools. Soap powders, bleaches, waxes or other cleaning compounds, plastic or plastic containers, gasoline, kerosene, cigarette lighter fluid, dry cleaning fluids, or other volatile fluids. Paint thinners and other painting compounds, paper bags or other paper products. Installation Procedures — The following recommendations apply to the installation and operation of gas furnaces and piping systems for natural and LP gases. Use these procedures in conjunction with the specific furnace installation instructions. Refer also to the regulations of the serving gas supplier and the local building, heating, plumbing or other codes in effect in the area in which the installation is made. Portions of the following have been adopted in part from the “National Fuel Gas Code” (NFPA -> No. 54-1980 or ANSI Z223.1-1980) copyrighted by the National Fire Protection Association and American Gas Association. For further details, consult this publication or current edition available from NFPA, 470 Atlantic Avenue, Boston, MA 02210, or American Gas Association, 1515 Wilson Boulevard, Arlington, VA 22209.

Check the available gas supply to see that it conforms to the gas specification on the AGA rating plate. LOCATION AND AIR FOR COMBUSTION AND VENTILATION Locate the furnace close to the chimney and as near the center of the air distribution system as possible. Provide ample space for servicing and cleaning. Always comply with minimum fire protection clearances shown on the unit rating plate. Do not install directly on carpeting, tile or any combustible material other than wood flooring. If base for combustible floor is required, obtain from Carrier distributor or dealer. © Carrier Corporation 1982 Form 58-9XA ff *1 .r The draft hood relief air supply must be in the same atmospheric pressure zone as the combustion air inlet supply to the furnace. When a furnace is installed so that 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 space containing the furnace. All fuel-burning equipment must be supplied with air, which enters into the combustion process and is then vented to the outdoors. Sufficient air must enter the equipment room to replace that drawn up the vent stack. Replacement air must be provided by means of ducts from the outside to the equipment location or conditioned space. Under all conditions, enough air must be provided to ensure there will not be a negative pressure condition within the equipment room or space. 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 clos...
