Only the latest issues of above codes should be used, and areavailable from either The National Fire Protection Agency, Bat-terymarch Park, Quincy, MA 02269 or The Canadian StandardsAssociation, 178 Rexdale Blvd., Rexdale, Ontario M9W 1R3.Recognize safety information. This is the safety-alert symbol .When you see this symbol on the furnace and in instructions ormanuals, be alert to the potential for personal injury.Understand the signal words DANGER, WARNING, and CAU-TION. These words are used with the safety-alert symbol. DAN-GER identifies the most serious hazards which will result in severepersonal injury or death. WARNING signifies a hazard whichcould result in personal injury or death. CAUTION is used toidentify unsafe practices which would result in minor personalinjury or product and property damage.When operating furnace in heating mode, static pressure andtemperature rise (supply-air temperature minus return-airtemperature) must be within those limits specified on ratinglabel. Failure to follow this warning could lead to severefurnace damage.INTRODUCTIONThis furnace is a 3-position unit that may be operated in upflow,horizontal left, or horizontal right airflow positions. Very fewmodifications are required to change furnace from 1 position toanother at job site. The furnace is shipped in the upflow configu-ration. Instructions for changing to other configurations are foundin Changing from Upflow to Horizontal section of these instruc-tions.The furnace is shipped as a packaged unit, complete with burnerand controls. It requires a line voltage (115 vac) connection tocontrol box, a thermostat hook-up as shown on wiring diagram, oilconnection(s), adequate ductwork, and connection to a properlysized vent.The air handling capacity of this furnace is designed for coolingairflow. Refer to Table 3 for expected airflows at various externalduct static pressures.LOCATIONThis 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.For an attic installation, it is important to keep insulation 12in. or more away from any furnace openings. Some types ofinsulating materials may be combustible.This furnace is approved for reduced clearances to combustibleconstruction, therefore, it may be installed in an alcove or similarenclosure. It is also approved for attic installation. As this unit maybe installed as an upflow or horizontal furnace, it may be locatedin a basement, on the same level as area to be heated, suspended,or in a crawlspace. In any case, unit should always be installedlevel.In a basement or when installed on the floor (as in a crawlspace),it is recommended that unit be installed on a concrete pad that is1- to 2-in. thick.When installed in horizontal position, furnace may be suspendedby using an angle iron frame, as long as total weight of bothfurnace and frame are allowed for in support calculations. Othermethods of suspending are acceptable.The required minimum clearances for this furnace in all positionsare specified in Table 1.The furnace should be located as close as possible to chimney orvent in order to keep vent connections short and direct. Thefurnace should also be located as near as possible to center of airdistribution system.Step 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 a fire hazard and/or bodily harm.This 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.Table 1—Minimum Clearances to Combustible Ma-terials (In.)UNIT APPLICATION UPFLOW HORIZONTALSidesFurnace 2 2Supply Plenum and Warm-AirDuct Within 6 ft of Furnace 1 1Back 2 2TopFurnace Casing or Plenum 2 2Horizontal Warm-Air DuctWithin 6 ft of Furnace 2 3Bottom 0* 0*FluePipeHorizontally or Below Pipe 9 9Vertically Above Pipe 9 9Front 24 24* Floor may be combustible.NOTE: Adequate service clearance should be provided over and above thesedimensions as required.2
