INSTALLATION DIAGRAMS

An installation diagram must generally be adapted to the man-

ufacturing characteristics of the relevant heating unit, with the 

purpose of exploiting the boiler potentials to the full and main-

tain the entire installation efficient for as long as possible. 

The  “Figure 9” is shown a installation with a mixing element.
