Caution
To analyse the products of combustion, ensure adequate heat
exchange in the system in heating mode or in domestic water
mode (by opening one or more domestic hot water cocks) to avoid
the boiler shutting down as a result of overheating. For correct
boiler operation, the CO
must be within the tolerance range indicated in the table below.
Activating the chimney sweep function
1. Press the two keys on the left simultaneously to select chimney sweep
mode.
When the letter L appears on the display (followed by the flow
temperature) the boiler is working at minimum power.
2. Press the F3 button
When the letter h appears on the display (followed by the flow
temperature) the boiler is working at maximum power in HEATING
MODE.
3. Press the F3 button
When the letter H appears on the display (followed by the flow
temperature) the boiler is working at maximum power in DOMESTIC
WATER MODE.
Important
This function is carried out in heating mode. During this function,
for LOW TEMPERATURE systems (such as underfloor heating),
the flow temperature is limited by setting CP000 (maximum flow
temperature).
To activate the domestic water mode, configure the setting to
GP082=1
Once finished, return the setting to GP082=0
4. To return to the home screen, press the F1 button
Caution
Remember to return the setting to GP082=0 once the chimney
sweep function is no longer in use.
