If all the above checks are negative, it is likely that the depression inside the stove drops due to poor performance of the ue, especially
when the machine is operating at minimum speed for a long time.
In this case it is possible to make small adjustments that allow you to increase the operating speed of the smoke fan to increase the
depression inside the product, or make it less sensitive to the intervention of the pressure switch by changing its position mechanically.
While the rst adjustment has no impact on the level of safety, the second one described aects it considerably and therefore should only
be performed by authorised and specialised personnel after carrying out all the inspections mentioned above.
Changing the smoke fan revolutions
In order to further improve combustion in critical conditions, you can change the percentage of the parameters for the minimum amount
of incoming combustion air. These changes can be performed upwards in the event of serious diculties in evacuating smoke and/or air
intake or downwards in the event of excessive draught of the ue.
