Firing Modes N/A

Evolution boilers are available in Full Modulation. Full modulation is achieved using a VFD and an air-fuel ratio modulating control valve. The control valve is actuated by an air signal from the fan - as the fan varies so does the gas valve. It is truly a linkage-less system and allows for safe fuel-air combustion. The full modulation uses a digital operating controller for infinitely proportional firing. Full modulation is available in models 500-3000 MBH input.

The Evolution boiler is available as a single or multi phase electric input, both 50 and 60 hertz. With no requirement for step-down transformers, the Evolution package comes complete and ready for single point electrical connection.
