172. GH ALTITUDEDERATE When this furnace is installed at high altitude the appropri ate High Altitude orifice kit must be applied This is required due to the natural reduction in the density of both the gas fuel and combustion air as altitude increases The kit will provide the proper design certified input rate within the speci fied altitude range High altitude kits are purchased according to the installa tion altitude and usage of either natural or propane gas Refer to the product Specification Sheet or Technical Manual for a tabular listing of appropriate altitude ranges and correspond ing manufacturer s high altitude Natural Propane gas and or Pressure Switch kits Do not derate the furnace by adjusting the manifold pres sure to a lower pressure than specified on the furnace rating plate The combination of the lower air density and a lower manifold pressure will prohibit the burner orifice from draw ing the proper amount of air into the burner This may cause incomplete combustion flashback and possible yellow tip ping In some areas the gas supplier may artificially derate the gas in an effort to compensate for the effects of altitude If the gas is artificially derated the appropriate orifice size must be determined based upon the BTU ft content of the derated gas and the altitude Refer to the National Fuel Gas Code NFPA 54 ANSI Z223 1 and information provided by the gas supplier to determine the proper orifice size A
