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.
