Checks
7.6.1 Chimney sweep 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. A combustion analysis should not be conducted until a
satisfactory inlet working pressure test has been completed.
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
