PERFORMANCE DATA (cont)
FAN RPM AT MOTOR PULLEY SETTINGS* — 580F036-073
*Approximate fan rpm shown.
†Indicates alternate motor and drive package.
**Indicates high-static motor and drive package.
††Indicates standard motor and drive package.
FAN RPM AT MOTOR PULLEY SETTINGS* — 580F090-151
*Approximate fan rpm shown.
†Indicates standard motor and drive package.
**Indicates alternate drive package only.
††Indicates high-static motor and drive package.
***Indicates alternate motor and drive package.
ALTITUDE COMPENSATION* — 580F036-073
STANDARD UNITS
*As the height above sea level increases, there is less oxygen per cubic foot of air.
Therefore, heat input rate should be reduced at higher altitudes.
†Orifices available through your local Bryant distributor.
ALTITUDE COMPENSATION* — 580F036-073
LOW NOx UNITS
*As the height above sea level increases, there is less oxygen per cubic foot of air.
Therefore, the input rate should be reduced at higher altitudes.
†Orifices are available through your local Bryant distributor.
ALTITUDE COMPENSATION* — 580F090-151
*As the height above sea level increases, there is less oxygen per cubic foot of air.
Therefore, heat input rate should be reduced at higher altitudes.
†Orifices available through your local Bryant distributor.
ALTITUDE DERATING FACTOR*
*Derating of the unit is not required unless the heating value of the gas exceeds the val-
ues listed in the table above, or if the elevation exceeds 6000 ft. Derating conditions
must be 4% per thousand ft above 2000 ft. For example, at 4000 ft, if the heating value
of the gas exceeds 1000 Btu/ft
3
, the unit will require a 16% derating. For elevations
above 6000 ft, the same formula applies. For example, at 7000 ft, the unit will require a
28% derating of the maximum heating value per the National Fuel Gas Code.
IMPORTANT:
Local utility companies may be reducing heat content of gas at altitudes
above 2000 ft. If this is being done, changing spuds may not be required.
