About this file
This is a product submittal sheet for Lochinvar Knight Fire Tube Boilers, available in both floor and wall-mounted configurations. The document serves as a specification and ordering guide for commercial heating equipment.
The Knight Fire Tube Boiler series features 95% DOE AFUE efficiency across models ranging from 55 MBH to 399 MBH input capacity. Standard features include modulating burners with up to 10:1 turndown, direct spark ignition, low NOx operation, ASME stainless steel heat exchangers, and vertical or horizontal direct vent capabilities using PVC, CPVC, polypropylene, or stainless steel venting up to 100 feet. The advanced Smart System Digital Operating Control provides multi-color graphic LCD display with navigation dial, three boiler setpoint temperature inputs, built-in cascading sequencer for up to eight boilers, outdoor reset control with programmable reset curves, and four pump control options including variable speed boiler pump and DHW recirculation. Additional Smart System capabilities include building management system integration via 0-10 VDC inputs/outputs and Modbus contacts, data logging (runtime hours, ignition attempts, lockout history), maintenance reminders with contractor contact information, low-water flow safety control, and customizable freeze protection. Optional equipment includes Con-x-us Remote Connectivity Modbus communication, BACnet MSTP, flow switch, low-water cutoff with manual reset, alarm bell, condensate neutralization kit, BMS gateway integration, sidewall vent termination, wireless outdoor sensor, LP gas conversion kit, and firing code options (M9 Standard Construction or M7 California Code). Six floor-mount models (KHB055N through KHB285N) and seven wall-mount models (WHB055N through WHB399N) are specified with detailed dimensional data, connection sizes, and shipping weights provided.
