7FIRE, INJURY OR DEATH HAZARDFailure to follow this warning could result in personalinjury, death, and/or property damage.When the furnace is installed in a residential garage, theburners and ignition sources must be located at least 18inches (457 mm) above the floor. The furnace must belocated or protected to avoid damage by vehicles. When thefurnace is installed in a public garage, airplane hangar, orother building having a hazardous atmosphere, the furnacemust be installed in accordance with the NFGC. (See Fig.5.)! WARNING18-IN. (457.2 mm)MINIMUM TO BURNERSA93044Fig. 5 -- Installation in a GarageFIRE HAZARDFailure to follow this warning could result in personalinjury, death and/or property damage.Do not install the furnace on its back or hang furnace withcontrol compartment facing downward. Safety controloperation will be adversely affected. Never connectreturn--air ducts to the back of the furnace. (See Fig. 6.)! WARNINGA02054Fig. 6 -- Prohibit Installation on BackPROPERTY DAMAGE HAZARDImproper use or installation of this furnace may causepremature component failure. This gas furnace may be usedfor construction heat provided that:--The furnace is permanently installed with all electricalwiring, piping, venting and ducting installed according tothese installation instructions. A return air duct is provided,sealed to the furnace casing, and terminated outside thespace containing the furnace. This prevents a negativepressure condition as created by the circulating air blower,causing a flame roll--out and/or drawing combustionproducts into the structure.--The furnace is controlled by a thermostat. It may not be”hot wired” to provide heat continuously to the structurewithout thermostatic control.--Clean outside air is provided for combustion. This is tominimize the corrosive effects of adhesives, sealers andother construction materials. It also prevents theentrainment of drywall dust into combustion air, which cancause fouling and plugging of furnace components.--The temperature of the return air to the furnace ismaintained between 55_F (13_C) and 80_F (27_C), withno evening setback or shutdown. The use of the furnacewhile the structure is under construction is deemed to beintermittent operation per our installation instructions.--The air temperature rise is within the rated rise range onthe furnace rating plate, and the gas input rate has been setto the nameplate value.--The filters used to clean the circulating air during theconstruction process must be either changed or thoroughlycleaned prior to occupancy.--The furnace, ductwork and filters are cleaned as necessaryto remove drywall dust and construction debris from allHVAC system components after construction is completed.--Verify proper furnace operating conditions includingignition, gas input rate, air temperature rise, and ventingaccording to these installation instructions.CAUTION!LOCATION RELATIVE TO COOLING EQUIPMENTThe cooling coil must be installed parallel with, or on thedownstream side of the unit to avoid condensation in the heatexchangers. When installed parallel with the furnace, dampers orother flow control must prevent chilled air from entering thefurnace. If the dampers are manually operated, they must beequipped with means to prevent operation of either unit unlessthe damper is in the full--heat or full--cool position.AIR FOR COMBUSTION ANDVENTILATIONProvisions for adequate combustion, ventilation, and dilution airmust be provided in accordance with:U.S. installations: Section 9.3 of the NFPA 54 /A ANSIZ223.1--2012, Air for Combustion and Ventilation, andapplicable provisions of the local building codes.58CT
