Note:
To reliably prevent burner corrosion caused by condensation of exhaust gases, the burner outlet temperature must
not by any means be below 65°C. To do so, a burner circuit pump should be provided with a modulating valve as
per the diagram.
The burner circuit should be configured such that the temperature difference between the forward and return flow is
equal to or less than 15°C.
This is given in the design below, if no additional resistors are installed in the burner/accumulator circuit. Any
installation of slide valves or of a heat meter in the burner/accumulator circuit will require reconfiguration of the
burner pump and burner control valve by the heating technician
For incorporation of heat consumers, refer to Spec Sheets 4000ff.
