Secondary air adjustment
The smoke extractor fan located on the back of the boiler supplies the primary combustion air. The boiler is equipped
with a factory-set secondary air adjustment device, which must be checked with the aid of a combustion analyser in the
first lighting stage. The adjustment screw can subsequently be used to adapt the supply of secondary air according to
the quality and type of fuel.

• Large, wet are hard to burn wood: close 1 notch.
• Dry and very flammable wood: open 1 notch or more.
• If the boiler tends to puff due to very wet fuel, close it gradually.
System pressure adjustment
Periodically check that the system is full of water. These checks must be carried out cold, checking the expansion tanks
(open types must have water at the initial level, whereas in closed types the pressure must be equal to or higher than
the initial prefilling pressure).
