* As the height above sea level increases, there is less oxygen per cubic ft. of air. Therefore, heat input rate should be reduced at higher altitudes.

Minimum Heating Entering Air Temperature
When operating on first stage heating, the minimum
temperature of air entering the dimpled heat exchanger is
50_F(10_C) continuous and 45_F(7_C) intermittent for
standard heat exchangers and 40_F(4_C) continuous and
35_F(2_C) intermittent for stainless steel heat
exchangers. To operate at lower return or mixed air
temperatures, a field--supplied outdoor--air thermostat
must be used to initiate both stages of heat when the
temperature is below the minimum required temperature
to ensure full fire operation. Wire the outdoor--air
thermostat (OALT) (part no. HH22AG106) in series with
the second stage gas valve. See Fig. 62. Set the
outdoor--air thermostat at 35_F(2_C) for stainless steel
heat exchangers or 45_F(7_C) for standard heat
exchangers. This temperature setting will bring on the
second stage of heat whenever the ambient temperature is
below the thermostat setpoint. Indoor comfort can be
compromised when heating is initiated using low entering
air temperatures with insufficient heating temperature rise.
