Please note
Incorrect operating materials result in damage to
the appliance and increased emissions.
Only operate the boiler with logs. Do not heat
with sawdust, fines (wood or coal), coke, bri-
quettes, etc.
Wood moisture
The rated boiler heating output can only be achieved
with dry wood with a maximum moisture content of
between 15 and 20 % (net calorific value
Storing wood
■
Split round timbers that have a diameter of 10 cm or
more.
■
Stack the logs in a ventilated and preferably sunny
spot underneath a rain canopy.
Stack the logs with generous air gaps to allow the
■
flowing air to absorb the dissipating moisture.

1. Check the heating system pressure at pressure
gauge
The system pressure is too low if the indicator
points to the area below the red field. In this case,
top up with water or notify your heating contractor.
Minimum system pressure: 1.0 bar (0.1 MPa).
2. Check that the vents in the installation room are
unrestricted.
Note
With open flue operation, the combustion air is
drawn from the installation room.
3. Verify that the heating system or the heating water
buffer cylinder is drawing off heat. Open the ther-
mostatic valves on the radiators if necessary.
4. Check that the heating system has been vented.
5. Ensure that all shut-off gate valves to the heating
flow and return are open.
6. Check that all doors and covers on the boiler are
closed.
7. Ensure that all ball valves for the return tempera-
ture raising facility are open.
8. Ensure that power is supplied to the boiler.
This boiler is only suitable for the combustion of natu-
ral logs. To achieve optimum combustion, use split
logs if at all possible.
A higher wood moisture content reduces the net calo-
rific value and consequently output as well. Further-

deposits in the hopper.
■
A hollow should be created underneath the wood
pile, e.g. in the form of support timbers, to allow
moist air to escape downwards.
