6.9 - WARNINGS
HOW TO AVOID CORROSION IN THE
WOOD STORAGE COMPARTMENT
The use of wood with a high moisture content (higher than
about 25%) and/or loads not proportioned to the
system’s heat request (long OFF periods with the
wood storage full) can cause considerable
condensate formation in the storage compartment’s
internal wall.
Check the steel walls of the upper wood storage once a week.
They must be covered by a slight layer of dry tar, opaque
coloured, with bubbles tending to break and fall off.
On the contrary, if the tar is bright, runny and, if removed with
the fire stoke, some liquid appears: it is necessary to use wood
with a lower moisture content and/or to reduce the quantity of
the wood when loading the boiler.
If, despite these interventions, the tar does not dry, you must
inform the local After-Sales Service.
The condensate inside the firewood storage compartment
causes the steel sheets to corrode.
Corrosion is not covered by the warranty, as it is caused
by improper use of the boiler (wet wood, excessive loading,
etc.).
CORROSION OF THE FLUE GAS CIRCUIT
Flue gas is rich in water vapour, due to combustion and the use
of wood which retains water.
If the flue gas comes into contact with relatively cold surfaces
(having a temperature below 60 - 70 °C), the water vapour
condensates and, combining with other combustion products,
originates corrosion of the metallic parts.
Check daily whether there are signs of flue gas condensation
(black liquid on the floor and behind the boiler). In this case you
must use wood with a lower moisture content; check that the
recirculation pump is working correctly and the flue gas tempe-
rature at partial load, and increase the working
temperature. In order to control the room temperature, it is
therefore necessary to install a mixer valve.
The corrosion
caused by the flue gas condensation is not covered by the
warranty, as it is caused by the wood’s moisture content
and the way the boiler is used.
WARNINGS DURING USE
At the end of the day, check the surfaces of the combustion
chamber and the door insulation as they should be white.
There must be only a few unburnt embers in the ash deposited
in the cradle.
Always open the loading door and the internal anti-smoke door
slowly.
6.10 - ADJUSTMENT OF FLOW
TEMPERATURE
The flow temperature of the boiler can be set
as you wish (the adjustment range set by the
User varies from 65° to 85°C): See the System
manager operating instructions, page 7
“Programming mode”.
To adjust the flow temperature of the heating
system (for low temperature plants) a 3 or 4-way
mixer valve must be fitted.
Failure to install the valve makes the warranty null and void.
The manually reset safety thermostat complies with relevant
provisions in force.
When commissioning the boiler, make sure that it does not need
to be reset.
In order to do this, unscrew the plastic protective cap and press
the release button. Afterwards put the plastic cap back on.
Should the boiler’s safety thermostat trigger frequently, reduce
the flow temperature.
If the problem repeats itself, alert the After-Sales Service.
6.11 - SUMMER MODE
The use of the boiler in summer only for the
production of domestic hot water is not advised,
unless you follow these rules meticulously:
1) Use very dry wood.
2) Load a small amount of wood in the
boiler 2 or 3 times a day as needed.
