Never leave the suction flap rod in the open position during the boiler operation. Otherwise, the
fuel in the filling shaft will burn upwards, not through the nozzle. This may cause damage to the
metal parts in the filling shaft or damage to the suction flap. Not to mention that all of your heat
would have fled to the chimney before it was transferred to the water.
18. EXTINCTION
The boiler is extinguished when the flue gas temperature drops below 45°C and the user does not add more fuel. The fan stays in
the deactivated position, there is the Extinction word shown on the display.
The boiler can be extinguished manually at any by entering 'Extinction' in the menu. This will deactivate the fan but be careful – if
there is still fuel in the filling shaft, it will still burn according to the natural chimney draft. Similarly, combustion products will still
accumulate in the boiler. Therefore, even after extinguishing, when opening the door, follow the instructions in the Adding fuel
section. If you open the filling door too quickly without an open suction flap, the smoke will escape into the room.
19. MAINTENANCE
The boiler must be cleaned regularly. Not only the filling shaft and combustion chamber, but also the heat exchanger. Follow the
instructions below to keep your boiler in the best possible condition.
1.
Filling shaft: Open the filling door and move the residual ash through the nozzle to fall down into the combustion chamber
or vacuum it out using an ash vacuum. Clean the side shield plates in the filling shaft with a scraper if necessary.
2.
Combustion chamber: Open the bottom door and remove all the ash from the combustion chamber. Check the correct
position of all fireclay bricks before closing to prevent the stopping of exhaust fumes flowing from the combustion
chamber to the boiler heat exchanger.
3.
Boiler heat exchanger: Remove the cleaning door at the top of the boiler. You'll find a shielding flap below them, which
you also remove. Now you can clean the heat exchanger walls using a scraper and brush supplied with the boiler. The
residual ash falls to the bottom of the heat exchanger under the boiler dividers. This ash can either be vacuumed using
an ash vacuum with a longer extension so that you get under the dividers. If you do not have an ash vacuum, use cleaning
openings on both sides of the boiler to remove residual ash from the bottom of the heat exchanger; see point 4.
4.
Cleaning opening: There is a small cover at the underside of the boiler (left and
right), which serves to remove ash that falls under the heat exchanger. Remove
the cover sheet first on the boiler's side casing, then unscrew the 2 wing nuts to
remove the metal plate. Using a cleaning tool, remove the ash out onto a shovel
or use a vacuum cleaner.
5.
Exhaust fan: Before the season, we recommend unscrewing the exhaust fan and
removing the ash that has accumulated behind the fan in the spiral cabinet.
Carefully wipe the fan propeller with a brush and check its attachment, it must
not wobble. If it is not firmly attached, tighten the lock nut that holds the propeller on
the fan shaft.
After cleaning, be sure to restore the boiler to its original state. Close all the doors, screw the cleaning opening back in,
tighten the fan in an airtight manner and make sure all the components (firebricks, cover plates in the filling shaft,
turbulators, shielding flap) are in the right place.
20. RISK ANALYSIS
Residual risks and their prevention. The risks arising from the boiler's operation under conditions of foreseeable use and
reasonably foreseeable misuse have been minimised by available technical means. Despite the design and technical measures
