Now in its fourth generation, the designed, engineered and assembled in the U.S.A. KNIGHT Fire Tube Boiler contains 13 models, seven wall-mount options (55,000 to 399,000 Btu/hr) and six floor-standing models (55,000 to 285,000 Btu/hr), with turndown ratios of up to 10:1.
To achieve performance and reliability for building owners, the KNIGHT Fire Tube Boiler includes a corrosion-resistant stainless steel fire-tube heat exchanger and a negative regulation combustion system. Additionally, each KNIGHT boiler will be packaged with a variable-speed ECM circulator, which can save up to 90 percent on operational costs over a conventional circulator.
Every KNIGHT Fire Tube Boiler comes equipped with SMART SYSTEM, a boiler control system, which includes the CON·X·US Remote Connect option and the LOCH-N-LINK USB Programming feature. The Set-Up Wizard guides contractors through installation programming while the CON·X·US Remote Connect option allows a technician or building owner to monitor and manage the boiler from a mobile app.
Lightweight with a compact footprint, the entire series is designed to make installation, setup and serviceability straightforward for contractors. For instance, the KNIGHT Fire Tube Boiler features:
- LOCH-N-LINK USB Programming with parameters uploaded from a thumb drive
- A universal vent adapter, which allows for transition to multiple types of vent material
- A variable-speed pump that increases system efficiency and reduces operational costs
- Dual location parameter memory for component replacement
- An electrical outlet on the unit for a work light or condensate pump
- Wall- and floor-mount options with top and bottom water connections
KNIGHT Fire Tube boilers can be cascaded together for redundancy and may also be paired with an indirect water heater.
The condensing gas KNIGHT Fire Tube Boiler series first launched in 2005. Since its introduction and through four generations, the KNIGHT Fire Tube boiler has established a reputation for performance among contractors.
