Notes:

Lower gas supply pressure configurations available for New York City requirements


  • Firing rates based on altitudes to 2000ft. above sea level.
    *  For firing rates at higher altitudes, consult factory.
  • Gas input based on natural gas at 1,000 Btu/cu.ft. and 0.60 gravity
  • Oil input based on 140,000 Btu/gal. on M, 145,000 Btu/gal. on MM and 150,000 Btu/gal. on ME series.
  • Boiler overall efficiency of 80% estimated.
    *  Industrial Combustion does not guarantee overall boiler efficiency.
  • Gas pressure based on zero furnace pressure.
    *  For total pressure at manifold, add furnace pressure.
  • Impeller and motor HP is based on altitude up to 2,000 ft. above sea level, and up to 1.5" W.C. furnace pressure.
    *  For higher altitude or 50 Hz applications, consult factory.
