Notes:
- Firing rates based on 60 cycle and altitudes to 2000 feet above sea level.
* For blower wheel and motor sizes at higher altitudes, and 50 cycle applications, consult factory. - Oil input based on No. 2 oil @ 140,000 Btu/gal.
- Gas input based on Natural Gas @ 1,000 Btu/cu.ft. and 0.60 specific gravity.
- Lower furnace pressures may reduce motor HP requirements
- Boiler overall efficiency of 80% estimated.
