NOT move or shuffle your feet, DO NOT touch ungroundedobjects, etc.).4. If you touch ungrounded objects (recharge your body withstatic electricity), firmly touch furnace again before touchingcontrol or wires.5. Use this procedure for installed and uninstalled (ungrounded)furnaces.6. Before removing a new control from its container, dischargeyour body’s electrostatic charge to ground to protect thecontrol from damage. If the control is to be installed in afurnace, follow items 1 through 5 before bringing the controlor yourself into contact with the furnace. Put all used ANDnew controls into containers before touching ungroundedobjects.7. An ESD service kit (available from commercial sources) mayalso be used to prevent ESD damage.INTRODUCTIONThe model 58ZAV Series 141 Furnaces are available in sizes50,000 through 135,000 Btuh input capacities.The design of the downflow/horizontal gas-fired furnace isA.G.A./C.G.A. certified for natural and propane gases and forinstallation on noncombustible flooring. The furnace is factory-shipped for use with natural gas. The manufacturer’s accessory gasconversion kit is required to convert furnace for use with propanegas.These furnaces SHALL NOT be installed directly on carpeting,tile, or any other combustible material other than wood flooring. Indownflow installations, the manufacturer’s accessory floor basemust be used when installed on combustible materials and woodflooring. Special base is not required when this furnace is installedon manufacturer’s Coil Assembly Part No. CD5 or CK5, or whenCoil Box Part No. KCAKC is used. This furnace is for installationin alcoves, attics, crawlspaces, basements, closets, or utility rooms.The design of this furnace line is not A.G.A./C.G.A. certified forinstallation in mobile homes, recreation vehicles, or outdoors.Before installing the furnace, refer to the current edition of theNFGC and the NFPA 90B. Canadian installations must be installedin accordance NSCNGPIC and all authorities having jurisdiction.For a copy of the NFGC NFPA54/Z223.1, contact InternationalApproval Services U.S. Inc., 8501 E. Pleasant Valley Road,Cleveland, OH 44131 or National Fire Protection Association Inc.,Batterymarch Park, Quincy, MA 02269. For a copy of NFPA 90B,contact National Fire Protection Association Inc., BatterymarchPark, Quincy, MA 02269.Before installing the furnace in Canada, refer to the current editionof the NSCNGPIC. Contact Standards Department of CanadianGas Association, 55 Scarsdale Road, Don Mills, Ontario, CanadaM3B 2R3.Application of this furnace should be indoors with specialattention given to vent sizing and material, gas input rate, airtemperature rise, and unit sizing. Improper installation ormisapplication of the furnace can require excessive servicingor cause premature component failure.Installation must conform to the regulations of the serving gassupplier and the local building, heating, and plumbing codes ineffect in the area in which the installation is made, or in theabsence of local codes with the requirements of the NFGC.This furnace is designed for a minimum continuous return-airtemperature of 60°F db or intermittent operation down to 55°F dbsuch as when used with a night setback thermostat. Return-airtemperature must not exceed a maximum of 85°F db.Improper installation, adjustment, alteration, service, mainte-nance, or use can cause carbon monoxide poisoning, explo-sion, fire, electrical shock, or other conditions which maycause personal injury, loss of life, or property damage.Consult a qualified installer, service agency, local gas sup-plier, or your distributor or branch for information or assis-tance. The qualified installer or agency must use onlyfactory-authorized and listed kits or accessories when modi-fying this product. Failure to follow this warning could resultin electrical shock, fire, personal injury, or death.For accessory installation details, refer to the applicable installa-tion literature.NOTE: Remove all shipping brackets and materials before oper-ating the furnace.Step 1—LocationGENERALDo not install furnace in a corrosive or contaminated atmo-sphere. Make sure all combustion and circulating air require-ments are followed, in addition to all local codes andordinances.Do not use this furnace during construction when adhesives,sealers, and/or new carpets are being installed. If the furnaceis required during construction, use clean outside air forcombustion and ventilation. Compounds of chlorine andfluorine when burned with combustion air form acids whichcause corrosion of the heat exchangers and metal vent system.Some of these compounds are found in paneling and dry walladhesives, paints, thinners, masonry cleaning materials, andmany other solvents commonly used in the constructionprocess.Excessive exposure to contaminated combustion air willresult in safety and performance related problems.This furnace must be installed so the electrical components areprotected from water.Locate the furnace as close to the chimney/vent and as near thecenter of the air distribution system as possible. The furnaceshould be installed as level as possible.When a furnace is installed so that the supply ducts carry air toareas outside the space containing the furnace, the return air mustalso be handled by a duct(s) sealed to the furnace casing andterminating outside the space containing the furnace.Provide ample space for servicing and cleaning. Always complywith the minimum fire protection clearances shown on the unitrating plate. This furnace shall not be installed directly oncarpeting, tile, or any combustible material other than woodflooring. The furnace may be installed on combustible flooringwhen installed with the accessory downflow subbase, which isavailable from your distributor or branch when required.LOCATION RELATIVE TO COOLING EQUIPMENT — Thecooling coil must be installed parallel with or on the downstreamside of the furnace to avoid condensation in the heat exchangers.When installed parallel with a furnace, dampers or other meansused to control the flow of air must prevent chilled air fromentering the unit. If the dampers are manually operated, they mustbe equipped with means to prevent operation of either unit unlessthe damper is in the full-heat or full-cool position.3→
