The Lochinvar Crest® FBN0751 is a commercial floor-mount condensing gas boiler delivering a precise input of 750,000 BTU/hr and a thermal efficiency rating of up to 96.2%. Engineered to revolutionize modern hydronic heating plant design, the Crest series utilizes a highly advanced, single-pass Wave Fire-Tube heat exchanger construction. This design achieves exceptional heat transfer while keeping waterside pressure drops low, allowing easy integration into variable primary or full-flow configurations without complex primary/secondary piping.

Equipped with a top-mounted micro-metal fiber burner and a negative regulation combustion framework, the boiler delivers smooth, quiet operation with an ultra-wide 15:1 modulation turndown ratio. It runs reliably even under drops in local utility gas pressures down to 4 inches water column. System diagnostics are managed through Lochinvar's signature SMART TOUCH™ touchscreen dashboard featuring CON·X·US® remote connectivity, letting facility teams monitor operation or adjust parameters from a remote location.
