10 Years Limited Coil, Heat Exchanger and Burner

All non-ferrous waterways - All castings are made of bronze or brass|All water tubes are made from copper|Brazed joints or flare union construction make the heater immune to the effects of thermal shock and thermal cycling|The Burkay® boiler provides one of the smallest foot prints in the industry|Efficient copper coil combustion chamber the combustion chamber is a heat exchanger formed from a two passage coil of tightly wound continuous copper tube|Water circulating through this coil captures radiant heat|A wrap of insulation on the outside of the coil retains the heat captured by the circulating water, up to 82% efficient|Copper heat exchanger - Directly above the coil and the main burner is a compact, horizontal, copper fin tube heat exchanger|The flue gases must pass through this efficient heat exchanger before leaving the boiler|This unique Burkay® coil and heat exchanger design provide maximum heat transfer and proven field durability|Models meet the thermal efficiency and standby loss requirements of the US department of energy and current edition of ASHRAE/IESNA 90.1|Burkay burner maximizes efficiency - The patented Burkay® burner designed to provide the highest level of primary air to 71 individual orifices while adding sufficient secondary air for proper combustion|Gas valves - Slow opening redundant gas valves ensure smooth light-off without flame roll-out or pilot outage|Thermal balancer - Factory supplied for use with primary secondary heating systems|Cycles the secondary pump with the burner, but delays pump shut off at the end of the heating cycle to remove usable heat from the boiler|Virtually eliminates stand-by heat losses at the boiler|Automatic safety controls and electronic ignition - Proven pilot ignition system provides flame failure response in under 1 second|Redundant high limit controls and gas valves assure safe shut off in the event of overheating or flame failure|To compensate for the effects of high altitude areas above 2000 ft, the input, output and heating load ratings should be reduced approximately 4% for each 1000 ft above sea level|CAT-I RM, ASME approved, hydrostatically tested and certified for 160 psi
