Electric wires that are fieldinstalled shall conform to the temperature limitation for 63ºF (35ºC) risewire when installed in accordance with instructions. Refer to Table 4 inthese instructions for specific furnace electrical data.The residential supply must have a bonded neutral.Annual Fuel Utilization Efficiency (AFUE) numbers are determined in accordance with DOE Test procedures.Wire size and over current protection must comply with the National Electrical Code (NFPA-70-latest edition) and all local codes.The furnace shall be installed so that the electrical components are protected from water.FIGURE 9: Gas PipingGROUNDUNIONDRIPLEGMANUALSHUT-OFFVALVEGROUNDUNIONDRIPLEGUPFLOWDRIPLEGDRIPLEGGROUNDUNIONMANUALSHUT-OFFVALVEGROUNDUNIONIMPORTANT: An accessible manual shutoff valve must be installedupstream of the furnace gas controls and within 6 feet (1.8 m) of thefurnace.CAUTIONThe gas valve body is a very thin casting that cannot take any exter-nal pressure. Never apply a pipe wrench to the body of the gas valvewhen installing piping. A wrench must be placed on the octagon hublocated on the gas inlet side of the valve. Placing a wrench to thebody of the gas valve will damage the valve causing improper opera-tion and/or the valve to leak.!CAUTIONUse copper conductors only.!Table 4: Ratings & Physical / Electrical DataInput Output NominalAirflow AFUEAir Temp.RiseMax.OutletAir TempBlower BlowerSizeRecommendedFuse or CircuitBreaker AmpsTotalUnitAmpsGas PipeConnection,NPTMBH kW MBH kW CFM m3 /min ºF ºC ºF ºC HP Amps60 17.6 48 14.1 1200 34.0 80.0 35-65 19-36 190 88 1/2 6.4 11 x 8 15 9.0 1/2"80 23.5 64 18.8 1600 45.3 80.0 35-65 19-36 190 88 1/2 6.4 11 x 10 15 9.0 1/2"100 29.3 80 23.4 2000 56.6 80.0 35-65 19-36 190 88 3/4 8.8 11 x 11 15 11.4 1/2"
