Quick Product Details: KN6

Condensing, High Efficiency: 600,000 BTUs

With 600,000 BTUs in a compact footprint, the KN6 features a fully modulating, cast iron design and boasts increased condensing efficiency when compared to common condensing, gas-fired boilers. Built strong to handle the increasing demands of today's commercial boiler applications, the KN6 is an ideal choice for boiler operations within corporate office facilities and educational centers.

Designed for increased boiler performance and longevity, the KN6 was engineered with an ultra-efficient Tru-Flow symmetric air/fuel coupling design that burns clean while ensuring proper combustion at all firing rates, as well as 5:1 modulation for maximum efficiencies at all levels of heat demand.
