Chimney sweeper function

The chimney sweeper function is used by the qualified mainte-
nance technician to check the mains gas pressure, detect the
combustion parameters and to measure the combustion effi-
ciency required by legislation in force.
This function lasts 15 minutes and is activated by proceeding
as follows:
– if the front panel has not already been removed, open the two
catches (1), unscrew the two screws (2), pull the front panel
(3) forwards and release it from the top by lifting it.
