The corrosion caused by flue gas condensation is not cov-
ered by the warranty, as it is caused by the wood’s moisture
content and the way the boiler is used.
WARNINGS DURING USE
Every time the air is adjusted, wait 5-10 minutes before proceed-
ing with the next adjustment. When you have established the
best air adjustment, at the end of the day check the surfaces of
the combustion chamber and the door insulation, which should
be white.
There must be only a few unburnt embers in the ash deposited
in the cradle.
If primary air is excessive , there will be embers and small
pieces of coal in the ashes, the flame will be quick, dry, a cooler
colour and will be noisier, excessively powerful.
If primary air is insufficient , the flame will be slow, small, it

Problem:
- The panel board does not switch on.
Remedy:
- Make sure the panel board is powered.
- Check integrity of the fuse on the board.
Problem:
- When opening the loading door there are blowbacks
and smoke escape.
Remedy:
- Open slowly.
- Use damper wood, make sure that the boiler has not
have prolonged downtime (see par. 3.15.3).
- Use larger logs.
- Consume the previous load of wood before reloading.
Problem:
- The boiler does not reach the requested temperature.
The flame is small and there is too much air.
Inspecting the wood storage, the formation of log bridg-
es is found.
Remedy:
- Check the length of the logs (see par. 3.15.2).
- Check the arrangement of the logs (see par. 3.15.2).
- Cut the logs in half (see par. 3.15.2).
- Use smaller blogs (round or square, about 5-7 cm
diameter).
- Mix medium-large sized logs (round or square, about
15-20 cm diameter) with small sized logs (see previous
point).
Problem:
- The boiler does not reach the required temperature.
The flame is very small.
Remedy:
- Check the fan.

will not lap the lower cradle, dragging few ashes and the heat
output will be insufficient.
If the flame is dark orange, the secondary air is insufficient and
the surfaces of the combustion chamber will not be white; if it is
small and blue, there is too much secondary air.
Always open the top loading door and the internal anti-smoke
door slowly.
If blowbacks occur regardless of this warning, it will be necessary
to use larger logs, a bit damper, and ensure the boiler does not
have prolonged downtime (reduce primary air), that no broken
bars, changes to the grates or foreign matter (nails, metal pieces)
have obstructed the hole in the refractory burner.
