The ClearFire®-CE (CFC-E) is a fully assembled, high-mass firetube condensing boiler with a large-water-volume pressure vessel. The high-mass design equates to a low pressure drop, reducing pumping energy with no minimum flow requirements.

The pressure vessel is also thermal shock proof, capable of high-delta-T system designs to maximize condensing and reduce flow rates. The highly effective fireside heating surface with industry leading AluFer® tubes leads to superior efficiencies in all operating conditions.

The modulating, premix burner control automatically adjusts the air/gas mixture for maximum burner efficiency. The linkageless burner provides 5:1 fully modulating turndown without the use of complex air/fuel mixing valves or mechanical devices.

The dual-return connections have the ability to increase condensing in the boiler and raise efficiencies by 6%+ more than a single-return boiler.

The ClearFire-CE provides the reliability and longevity that customers expect from Cleaver-Brooks. The CFC-E is designed to leverage the advantages of primary-variable-flow pumping systems with a small overall footprint, offering system flexibility and true operational efficiency without compromise. 

Features:

  • True counterflow-arrangement heat exchanger for maximum heat transfer
  • High-mass design in a compact footprint, ideal for retrofit applications
  • Duplex stainless steel combustion chamber, tubes and tubesheet offer excellent corrosion resistance
  • Dual-temperature returns for additional energy savings potential
  • Falcon total boiler control with lead-lag capability up to 8 boilers
  • Quiet operation, <70 dBA sound level at 3 feet
  • Fresh-air inlet connection for direct-vent combustion air
  • Low waterside pressure drop for reduced pumping energy requirements
  • Hinged burner for easy access
  • Thermal shock resistant
  • cULus listed
