2. Firmly touch a clean, unpainted, metal surface of the furnacechassis which is close to the control. Tools held in a person’shand during grounding will be satisfactorily discharged.3. After touching the chassis you may proceed to service thecontrol or connecting wires as long as you do nothing thatrecharges your body with static electricity (for example; DONOT 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.LOCATIONStep 1—GeneralDo not use this furnace during construction when adhesives,sealers, and/or new carpets are being installed and curing. Ifthe furnace is required during construction, use clean outsideair for combustion and ventilation. Compounds of chlorineand fluorine, when burned in combustion air, form acidswhich will cause corrosion of the heat exchangers and metalvent system. Some of these compounds are released frompaneling and dry wall adhesives, paints, thinners, masonrycleaning materials, and many other solvents commonly usedin the construction process. Excessive exposure to contami-nated combustion air will result in safety and performancerelated problems.Do not install furnace in a corrosive or contaminated atmo-sphere. Make sure all combustion and circulating air require-ments are met in addition to all local codes and ordinances.This furnace must be installed so the electrical components areprotected from water.Locate furnace as near the center of the air distribution system andchimney or vent as possible. The furnace should be installed aslevel as possible. When a furnace is installed so that supply ductscarry air to areas outside the space containing the furnace, returnair must also be handled by a duct(s) sealed to the furnace casingand terminating outside the space containing the furnace.Provide ample space for servicing and cleaning. Always complywith the minimum fire protection clearances shown on furnaceclearance-to-combustible construction label. This furnace shall notbe installed directly on carpeting, tile, or any combustible materialother than wood flooring.Step 2—Location Relative to Cooling EquipmentThe cooling coil must be installed parallel with or on downstreamside of furnace to avoid condensation in heat exchangers. Wheninstalled parallel with a furnace, dampers or other means used tocontrol flow of air must prevent chilled air from entering furnace.If dampers are manually operated, they must be equipped withmeans to prevent operation of either unit unless damper is infull-heat or full-cool position.Step 3—Hazardous LocationsWhen furnace is installed in a residential garage, it must beinstalled so that burners and ignition sources are located aminimum of 18 in. above floor. The furnace must be locatedor protected to avoid physical damage by vehicles. Whenfurnace is installed in a public garage, airplane hangar, orother building having a hazardous atmosphere, unit must beinstalled in accordance with requirements of National FireProtection Association, Inc. (See Fig. 4.)AIR FOR COMBUSTION AND VENTILATIONProvisions for adequate combustion and ventilation air must beprovided in accordance with Section 5.3, Air for Combustion andVentilation, of the NFGC or applicable provisions of the localbuilding codes.Canadian installations must be in accordance with NSCNGPICand all authorities having jurisdiction.Air for combustion must not be contaminated by halogencompounds, which include fluoride, chloride, bromide, andiodide. These elements are found in aerosol sprays, deter-gents, bleaches, cleaning solvents, salts, air fresheners, andother household products.All fuel-burning equipment must be supplied with air for combus-tion of fuel. Sufficient air MUST be provided to ensure there willnot be a negative pressure in the equipment room or space. Inaddition, a positive seal MUST be made between furnace cabinetand return-air duct to prevent pulling air from burner area and draftsafeguard opening into the circulating air.Fig. 4—Installation in a GarageA9304418-IN.
