ClearFire, the New Standard in CommercialHigh-Efficiency Firetube BoilersCLEARFIRE BOILERSThe ClearFire-W noncondensingcommercialhot water boiler offers highefficiency, low NOx technologyand as such satisfies demands foreconomy and environmental protection.It features the C-B ClearFire combustionsystem with pre-mix down firing burner.This advanced burner is fundamentalto the boiler achieving efficiencies upto 88% and NOx levels to less than 20PPM. The pre-mix burner is suitable foruse with natural gas. ClearFire boilersare available in 7 sizes with maximuminputs between 400 - 2,400 MBTU.They are suitable for central heating forworking pressures up to 125 psig.Key Design features:• ASME Section IV carbon steelconstruction, 125# design• 400 - 2,400 MBTU• Up to 88% efficiency• Up to 5:1 turndown• Low NOx at < 20 PPM• Advanced Falcon controlsseamlessly integrates up to 8 boilers• Uses the patented AluFer® tube• Compact footprint• Easy maintenance• Single pass design• Thermal shock resistanceCONTROLSC-B Falcon ControlsThe C-B Falcon is a total boiler controlthat provides our customers with theintegrated functionality needed toefficiently and economically operate theirboiler system, while providing necessarysafety and reliability.• A single source solution for totalBoiler control• Touch screen graphics with trending• Three configurable relays (pump/valve)• Post shutdown pump delay• Outdoor temperature reset• Supply & return water sensor• High limit cut-out with manual reset• Integrated Burner sequencing,alarming and lockout• Date/time stamping of lockouts andalerts• First out expanded annunciation, firingrate limiting, time of day (setback) andPID loops.• ModBus (RS485) Communications• Frost protection• Modulation VSD combustion control• UL RecognizedENHANCED EFFICIENCYEnhanced efficiency withsingle pass heat exchangerThe single pass ClearFire boiler has apremix burner downfiring into a verticalwater surrounded tube nest made up ofhigh efficiency AluFer® tubes.The extended heating surface andcorrosion resistant properties of theAluFer® tube ensure enhancing heattransfer and peak performance.AluFer ® TubesThe internationally patented AluFer®tube is the latest innovation in advancedheat transfer technology.The tube is constructed from an inner(fireside) aluminum alloy finned surface,die fitted within an outer steel tubeproviding exceptional heat exchangecharacteristics.The efficiency ofthe heat transfer isattributable to thefollowing factors:• Heat conductivity of the Alufer®insert is ten times greater than thatof carbon steel.• Internal finned surface of the Alufer®tube enlarges the heat exchangesurface fivefold.• Inner surface of the tube is dividedinto eight flow channels to createmaximum turbulence and heat transfer.User-friendly Touch ScreenGraphics
