Troubleshooting
The boiler burns
poorly.
Damp wood.
A ceramic boiler requires a high combustion temperature.
To achieve this, the wood must be dry with a moisture
content of 16 ±8%.
The wood is not adapted
to the boiler.
Its length should be 19.7 in. Its thickness should be such
that three to six pieces of wood have room on the width
of the grate.
Shaped wood, studs.
If evenly shaped pieces of wood are stacked on top of
each other, they form a solid lump of wood with little
surface for the fire to gain a hold on. Insert the wood
so that there is air between the pieces.
The wood gets stuck.
This occurs when the wood is bent and not adapted to
the combustion chamber. Adapt the wood to the boiler.
The chimney duct continues
downwards from the
connection to the boiler.
Turbulence may be formed, which takes away part of
the draught. Fill the underlying part with sand.
Insufficient supply air.
The supply air duct for the boiler room must have
at least the same area as the flue.
Check that the supply air valve is open.
Incorrect settings.
The O
2
probe has not been
calibrated.
Check the settings and calibrate the O
2
probe.
Smoke from the
boiler is entering the
boiler room.
Insufficient supply air.
See above
There must be a fresh air intake, > Ø7.1 in.
Mechanical ventilation.
Any mechanical ventilation in the room must not create
any negative pressure that disturbs the operation of
the boiler.
Insufficient basic draught
in the chimney.
See chimney requirements.
Smoke entering the boiler
room when wood is inserted.
Check that the bypass damper is working properly.
High flue gas tem-
perature.
Tar and soot in the tubes.
Caused by incorrect combustion. Check the wood, the
draught, the supply air and the operation. Sweep the boiler.
Tar and and a lot of
soot in the tubes.
Incorrect combustion.
See the item about high flue gas temperature.
Too much wood in relation to the heating requirements
or damp wood.
Incorrect connection.
Check.
Heat is not trans-
ferred from the boiler
to the accumulator.
Circulation pump too small. The pump must have sufficient capacity so that it can
transfer the heat. Replace with a bigger pump.
Air.
Vent.
Fault in accumulator control. Check that the charging package is working properly.
The fan does not
start.
Switches in position O.
Switch the switches to position I.
Forgot to connect the quick
connector.
Connect the quick connector.
Overheating protection
triggered.
Reset the overheating protection.
The safety valve
opens when the sys-
tem becomes hot.
Expansion tank too small.
See the ‘Expansion system’ section.
Prepressurisation in the
expansion tank too high/low.
Check the pressure in the tank.
