LOCATIONStep 1-GeneralThis furnace is not water tight and is not designed for outdoorinstallation. This furnace shall be installed in such a manneras to protect electrical components from water. Outdoorinstallation would lead to a hazardous electrical condition andto premature furnace failure.Do not use this furnace as a construction heater. Use of thisfurnace as a construction heater exposes furnace to abnormalconditions, contaminated combustion air, and lack of airfilters. Failure to follow this warning can lead to prematurefurnace failure and/or vent failure which could result in a firehazard and/or bodily harm.This furnace is approved for reduced clearances to combustibleconstruction, therefore, it may be installed in a closet or similarenclosure. It may be located in a basement or on the same level asarea to be heated. In any case, unit should always be installed level.The required minimum clearances for this furnace are specified inTable 1. The furnace should be located as close as possible tochimney or vent in order to keep vent connections short and direct.The furnace should also be located as near as possible to center ofair distribution system.Step 2-Location Relative to Cooling EquipmentWhen installing furnace with cooling equipment for year-roundoperation, the following recommendations must be followed forseries or parallel airflow:1. In series airflow applications, coil is mounted after furnace inan enclosure in supply-air stream. The furnace blower used forboth heating and cooling airflow.The coil MUST be installed on air discharge side of furnace.Under no circumstances should airflow be such that cooled,conditioned air can pass over furnace heat exchanger. Thiswill cause condensation in heat exchanger and possiblefailure of heat exchanger which could lead to a fire hazardand/or a hazardous condition which may lead to bodily harm.Heat exchanger failure due to improper installation may notbe covered by warranty.2. In parallel airflow applications, dampers must be provided todirect air over furnace heat exchanger when heat is desired andover cooling coil when cooling is desired.IMPORTANT: The dampers should be adequate to prevent cooledair from entering furnace. If manually operated, dampers must beequipped with a means to prevent operation of either cooling unitor furnace unless damper is in full cool or heat position.INSTALLATIONStep 1-Air for Combustion and VentilationInstallation of this furnace in an area where it will receivecontaminated combustion air must be avoided. Such contami-nation would include the following: ammonia, chlorine,hydrogen sulfide, halogenated hydrocarbons, carbon tetra-chloride, cleaning solvents, hydrochloric acid, water soften-ing chemicals, and similar chemicals. Failure to follow thiswarning will lead to premature rusting of heat exchanger andpossible premature furnace failure and/or vent failure whichcould result in fire hazard and/or bodily harm.Do not block combustion-air openings in the furnace. Anyblockage will result in improper combustion which may resultin a fire hazard and/or cause bodily harm.Step 2-GeneralThis furnace should be installed in a location in which facilities forventilation permit satisfactory combustion of oil, proper venting,and maintenance of ambient temperature at safe limits undernormal conditions of use. The location should not interfere withproper circulation of air within the confined space. (See NFPA-31,Section 1.5.)In addition to air needed for combustion, process air shall beprovided as required for: cooling of equipment or material,controlling dew point, heating, drying, oxidation or dilution, safetyexhaust, and odor control.In addition to air needed for combustion, air shall be supplied forventilation, including all air required for comfort and properworking conditions for personnel.The barometric draft regulator (included with furnace) shall beinstalled in same room or enclosure as furnace in such a manner asto prevent any difference in pressure between regulator andcombustion-air supply.Air requirements for operation of exhaust fans, kitchen ventilationsystems, clothes dryers, and fireplaces shall be considered indetermining the adequacy of a space to provide combustion-airrequirements.The lack of a proper amount of combustion air can lead to seriousfurnace operational problems. Some of these problems are:1. Excessive oil burner after drip and oil fumes.2. Sooting.Table 1-Minimum Clearances ToCombustible Materials (In.)UNIT APPLICATION LOW-BOYSidesFurnace 1Supply Plenum and Warm-Air Duct Within 6 ftof Furnace 1Back Service Clearance 19TopFurnace Casing or Plenum 2Horizontal Warm-Air Duct Within 6 ft ofFurnace 2Bottom* 0FluePipeHorizontally or Below Pipe 4Vertically Above Pipe 9Front 8* Floor may be combustible.NOTE: Adequate service clearances should be provided over and above thesedimensions as required.3
