CHECKING COMBUSTION
.
To ensure the product remains in perfect working order,
and to comply with current legislation, systematically check
the boiler at regular intervals.
To analyse combustion, proceed as follows:
- access the CALIBRATION & SERVICE phase by setting
the password as indicated in chapter "Adjustments"
- turn the domestic hot water temperature selector to
maximum heating power (parameter HH).
The boiler works at maximum power for 4 minutes.
- use appropriate tools on the taps fitted to the air
distribution box after removing the cover (fig. 49)
The first tap is connected to the air intake circuit and detects
infiltration of fumes from concentric outlets; the second is
directly connected to the fumes outlet circuit and is used
to detect combustion parameters and efficiency.
The fumes analysis probe must be fully inserted.
IMPORTANT: the function that switches off the boiler when
water temperature reaches a maximum of about 90 °C is
still enabled during the combustion analysis phase.
