High Altitude Derate
When this furnace is installed at high altitude, the appropri-
ate High Altitude orifice kit must be installed. This is re-
quired 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
specified altitude range.

Tabled data is based upon the furnace input being reduced for altitudes above sea level. U.S. 4% per 1,000 feet.
Canada 10% derate for 2,000-4,000 feet.
High altitude kits are purchased according to the installa-
tion altitude and usage of either natural or propane gas. Refer
to the chart above for a tabular listing of appropriate altitude
ranges and corresponding manufacturer's high altitude Natu-
ral Gas and Propane Gas kits. For a tabular listing of appro-
priate altitude ranges and corresponding manufacturer's High
Altitude Pressure Switch kits, refer to either the Pressure
Switch Trip Points & Usage Chart in this manual or the Ac-
cessory Charts in Service Instructions.
