The diverting valve switches the water to the plate heat exchanger of the "Domestic hot water production kit " when the flow switch detects
the passage of water towards the usage point and when the boiler temperature exceeds 61° C. When there is a request for hot water the
boiler operates at maximum steady state power level. See also paragraph 5.9.

CAUTION: it is mandatory to earth the heater / boiler. If this instruction is not observed serious damage, which is not
covered by warranty, will result to the body of the heater / boiler. Have an electrician check the earthing. There must
be no electric potential (volts) between the earth of the generator and the actual earth of the plant. To prevent
electrochemical corrosion of the boiler body do not use galvanised pipes and fittings. Dedicated ground wires must
be used to ground all other materials.
