*Gas input ratings are certified for elevations to 2000 ft. For elevations above 2000 ft, reduce ratings 2% for each 1000 ft above sea level. In Canada, derate
the unit 5% from 2000 to 4500 ft above sea level.
†Capacity and AFUE in accordance with U.S. Government DOE test procedures.
‡ Airflow shown is for top only
**Permissible voltage limits for proper furnace operation.
††Unit ampacity = 125% of largest component’s full load amps plus 100% of all other potential operating components (EAC, humidifier, etc.). ‡‡ Length shown is measured 1 way along wire path between unit and service panel for maximum 2% voltage drop.
***Required for installation on combustible floors when no coil box is used, or when any coil box other than a Bryant CD5 or CK5 cased coil is used.
