7.6 Checks and adjustments
7.6.1 Chimney sweeper function
The chimney sweep function makes the boiler operate at
maximum power ( Hi on the display) or minimum power ( Lo on
the display).
The chimney sweep function is used by the qualified maintenance
technician to check that the gas pressure at the nozzles is
correct (the front panel (2) MUST be open) and to detect the
combustion parameters (the front panel (2) MUST be closed).
This function lasts 15 minutes and is activated by proceeding
as follows:
– if the panel (2) has not already been removed, remove the
two screws (1), pull the front panel (2) forwards and release it
from the top by lifting it
