Adjust the maximum oil or gas through-
put of the burner to the rated boiler heat-

must be set to the rated boiler heating
output and must not be switched off dur-
ing summertime (burner stage 2 on con-
stant standby).

is 50 °C for operation with oil and 60 °C

A minimum flue gas temperature is
required for the base load stage, the
value of which is subject to the chimney
design.
