Description
This kit contains the appropriate burner orifices, and/or pressure switch assembly for the application of Amana Two-
Stage Gas-Fired furnaces in installations above altitudes of 7,000 feet. These kits are not applicable in Canada. Kits
apply as shown in the table below.

Installation Instructions
Above an altitude of 7,000 feet, a derating of the appliance must be followed since the CFM moved by the induced
draft blower remains almost constant while the pounds of oxygen in that air is reduced as altitude increases. If this
procedure is not followed and the fuel input is not reduced the resulting combustion can be inefficient, incomplete, or
possibly cause premature heat exchanger failure due to excessive temperature rise. The burner orifices in the high
altitude kits have been selected as a result of agency certified testing at high altitude. They will provide the appropri-
ate derating for all GUVA furnaces (Table 2). Orifice selection is based on non-derated gas (approximately 1,000
BTU/ft

for propane. If your gas supply has been derated for altitude, contact your gas supplier for orifice sizing.

GUVA Derates
Table 2
Do not derate by adjusting the manifold pressure to a lower pressure setting than what is specified on the furnace
nameplate. A lower air density in combination with a lower manifold pressure at the burner orifice will prevent the
orifice from aspirating the proper amount of air into the burner required for complete combustion.
In addition to using smaller orifices to reduce the fuel input, a different pressure switch must be used above the rated
altitude of 7,000 feet. A high altitude pressure switch is necessary as a result of the reduction in air density and is
required regardless of the heat content of the fuel used.
