Product Details

  • Efficient copper coil combustion chamber - continuous coils of tightly wound copper tubing form a unique combustion chamber, water circulating thru the coils, around the flame, captures radiant heat which may otherwise be lost
  • Unique Burkay® coil and heat exchanger design provide maximum heat transfer and proven held durability
  • The patented Burkay® burner maximizes efficiency, uses primary air injection at up to 72 individual orifices plus secondary entrainment of air, and approved for installation on combustible doors as shipped from factory
  • Slow opening redundant gas valves ensure smooth light-off without came roll-out or pilot outage
  • Thermal balancer - patented pump delay system that allows boiler and pump to run simultaneously but delays pump shut off at end of heating cycle to remove usable heat from the heat exchanger and reduce the scale forming tendencies of motionless hot water
  • Automatic safety controls and electronic ignition - proven pilot ignition system provides came failure response in under 1 second, redundant high limit controls and gas valves assure safe shutoff in the event of overheating or came failure
  • Working pressure - ASME approved, hydrostatically tested and carried for 160 psi, ships with ASME 125 psi relief valve
  • This model meets the thermal efficiency and standby loss requirements of the U.S. Department of Energy and current edition ASHRAE/IESNA 90.1
