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 automatically fires 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.
