of 120 kW at maximum (according to EN 676) must
be set. Consult to this end the instruction manual of
the front-mounted burner used,
- The air-proving switch must be set in such a way that
it cuts out before the CO contents of the flue gas

amounts to 25 Pa across the entire range. The
selected burner must be able to supply at least this
pressure.
