1.3.10
Fuse
The fuse located on the front of the control panel is 3.15 A (
∅
5 mm
×
20 mm).
It blows if overload appears – replace only with an equivalent. Contact an electrician if the
fuse blows frequently.
1.3.11
Quick break down search (considering that the hydraulic attachment is correct)
Case 1: The boiler works, but the temperature does not increase properly:
Or: The temperature increases but the storage tanks heat up with difficulty and the heating
is weak.
-
Check the air settings (open the primary air valve as necessary).
-
Check if the heat exchange pipes, the loading chamber and the combustion tunnel are
clean (see 1.3.12 Cleaning and maintenance).
-
Check if the primary air exit in the chamber (in front of you, behind the hanging plates,
just above stones) is cleared. Too great a layer of ash may be found in the burning
chamber, a more regular cleaning is required. After a few working years, a complete
cleaning of air ducts may prove useful: take out the air valves situated between the two
doors and clean all the ducts.
-
Check if the door seals, the hatches for ash removal are waterproof. A bad
waterproofness leads to an external unwanted air intake away from the combustion
which leads to a loss of power and a bad function.
-
Check the condition of the suction fan blade coupled to the motor (see 1.3.12 Clean and
maintenance).
-
Check the temperature of the flue gas: it must be in the range of 130°C to 150°C. If it is
too low, the wood is probably not suitable. Try with a different type of wood or different
stock.
-
Have the moisture content in the wood controlled with the help of a hygrometer (by
your installer).
-
Check the good hydraulic connection, in good equilibrium (heat pump(s))...
Case 2:
The boiler temperature increases but does not emit energy:
-
Check the good function of the recycling pump.
-
In the case of a "recyclable Kit D 60°C", check the openings of stop flaps and the
condition of the thermostatic cartridge, the heat pump motor (these components are
available as separate parts).
Case 3: The boiler stops when the wood is not consumed and the storage tanks are not loaded:
-
The minimum flue gas temperature is incorrectly set (the base adjustment is around
90°C), its sensor is not in its place, or it is defective (A4 alarm).
-
The wood may be too long, too wet, or in a bad position in the burning chamber: the
wood stays trapped, and does not subside during the combustion and it goes down until
there is no significant power, and the temperature of the flue gas decreases below the
minimum setting.
-
The combustion stifles by a lack of ash sweeping in the burning chamber or in the tunnel
or behind the tunnel, the power is lacking, the temperature decreases below the
minimum setting (H).
-
The wood is wet and the temperature of the flue gas is too weak (no power).
