Plus, all connections are on the top and left side, so KNIGHT is an easy drop-in replacement for older, less efficient boilers. Six models offer inputs from 55,000 to 285,000 Btu/hr. - t USE EXISTING PIPING TO REDUCE COSTS The KNIGHT fire tube boiler operates with low pressure drop.The design incorporates a small volume of water in the heat exchanger.This allows the boiler to be installed in a primary/secondary or a full-flow piped system.There is no need to change the piping to accommodate the boiler.The boiler adapts to i the system.This flexibility allows for a faster, more cost-effective boiler upgrade. 1 III 10:1 TURNDOWN RATIO OPTIMIZES PERFORMANCE Modulation turndown up to 10:1 means the firing rate automatically changes as the heat load varies.A KHN110 KNIGHT boiler fires at its maximum 110,000 Btu/hr rate when load is highest,then "turns down"to as low as 10% (11,000 Btu/hr) as load decreases.A modulating boiler runs smoothly 'I and efficiently,without frequent on/off cycling. SAFE, RELIABLE NEG/REG TECHNOLOGY . : KNIGHT boilers can operate with low gas supply pressure.Negative Regulation Ii , uses a pre-mix gas system instead of relying on utility pressure through the gas valve.The result is steady operation in low gas pressure systems or when gas s demand is highest.Automatic fan control fine-tunes the air/fuel ratio, Vier' providing superior combustion throughout the operating range. SUPERIOR DIRECT-VENTING FLEXIBILITY KNIGHT boilers can be installed with direct-vent air intake and exhaust runs up to 100 equivalent feet, using PVC, CPVC, polypropylene or AL29-4C stainless steel vent pipe.
