7.3.3. Service after motor bolt breakage
The connection between the motoreducer and the
lower axis is realized through a protection bolt. This is
designed in such a way so that it breaks in case of
feeder blockage, to protect the motor from burning.
If this bolt breaks, follow these steps to replace it:

Remove the two gears from the axes by
unscrewing the headless inserted screws keeping
them in place.
You do not need to unmake the
chain! Remove them all together with the chain.

Unscrew the nut and remove the broken bolt.

Introduce a new bolt M6x50 and tighten with the
nut from the other side.

Verify the causes of the breakage. If there is an
obstacle in the feeding pipe remove it.

7.3.4. Service after power blackout
In case there is a power blackout, it is absolutely necessary to perform some checks and take
some safety measures to avoid overheating. The solid fuel has all the time a certain amount of
fuel in the fire chamber, which will not stop burning immediately.
For safety reasons it is recommended you have installed a UPS with a battery,
which assures function of the boiler pump at least for 30 minutes.

Remove the amount of fuel that is still burning in the furnace. Due to power blackout, there
is risk of backfire to the silo.

Turn the control panel to OFF.

When the power is restored, turn on the control panel and make sure all the devices
function properly.
7.3.5. Replacement of the ignition element
In case you need to replace the ignition element follow the instructions:

Turn OFF the control panel and disconnect from electricity.

Disconnect the connection wires of the ignition element and loosen the plastic tap holding
them in place.

Remove the fan by unscrewing the four screws keeping it in place.

Remove the furnace plate. The ignition element is positioned inside the INOX tube casing.

Remove the ignition element from the tube and insert in position the new one.

When you position back the furnace plate, be careful to fix it correctly with the fixing tooth,
as shown on Fig 19.
