Capacities and Specifications

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 D/LND, 145,000 Btu/gal. on DM and 150,000 Btu/gal. on DE series.
  • Boiler overall efficiency of 80% estimated. Industrial Combustion does not guarantee overall boiler efficiency.
  • Furnace pressure and furnace dimensions and required NOx emissions may allow higher firing rates than shown above,
  •   consult factory
  • Motor horsepower based off of standard design backpressure rating.
    * Consult factory for review and comparison to your application.
  • Shipping weight is only an estimate
