2.2 General Boiler Operation
The boiler may be operated from the E8 controller or alternatively from a BCM (Boiler Cascade
Manager).
The boiler management logic provides the maximum number of simultaneously operating heating
elements in order to maximize heat production and overall efficiency. Burner efficiency and a high
heat exchange between surfaces contribute to the reliable and efficient output power. The various
components are designed to work together so that operating time is shared equally among the
components, thus reducing maintenance and labor costs.
The hot water moved by the pump is pushed to the return of the primary flow of the hydraulic
separator. From here a second pump will distribute the hot water to the various destinations. The
cooled return water is drawn by the pump through the hydraulic separator to resume the cycle via
the boiler.
WARNING!
If installing to an outdoor location where freezing temperatures may
occur, it is necessary to install devices and/or materials to prevent
any freezing in the condensate drain and the Flow and Return
manifolds. Failure to do so may cause serious damage to the
equipment.
