7.6.1 Chimney sweeper function
The chimney sweeper function is used by the qualified main-
tenance technician to check the mains gas pressure, detect
the combustion parameters and to measure the combustion
efficiency required by legislation in force.
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
