High Altitude Derate
IMPORTANT NOTE: The furnace as shipped requires no
change to run between 0 - 4500 feet. Do not attempt to
increase the firing rate by changing orifices or increasing
the manifold pressure below 4500 feet. This can cause poor
combustion and equipment failure.
High altitude installations above 4500 feet may require both
a pressure switch and an orifice change. These changes
are necessary to compensate for the natural reduction in
1
the density of both the gas fuel and the combustion air at
higher altitude.
For installations above 4500 feet, please refer to your dis-
tributor for required kit(s). Contact the distributor for a tabular
listing of appropriate manufacturer's kits for propane gas
and/or high altitude installations. The indicated kits must be
used to insure safe and proper furnace operation. All con-
versions must be performed by a qualified installer, or ser-
vice agency.
