Never leave the suction flap 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 given 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, on the display is the Extinction sign shown.
The boiler can be extinguished at any time manually by entering "Extinction" in the menu. This will deactivate the fan, but be
careful if there is still fuel in the filling shaft, this 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 Fuel loading section. If you open the filling door swiftly without an open suction flap, the smoke will escape into the room.
19. MAINTENANCE
The boiler must be cleaned regularly. And 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 by vacuum cleaner for hot ash. Clean the side shield plates in the filling shaft with a scraper if necessary.
2.
Combustion chamber: Open the bottom door and clean all the ash out of the combustion chamber. Check the correct
position of all chamotte bricks before closing to avoid bad air flow from the combustion chamber to the boiler exchanger.
3.
Heat exchanger: Remove the cleaning door at the top of the boiler. Below them you will find a shielding flap, which you
also remove. Now you can clean the walls of the heat exchanger using a scraper and brush supplied with the boiler. The
residual ash falls to the bottom of the exchanger under the heat exchanger. This ash can either be vacuumed with an ash
cleaner with a longer extension so that you get under the heat exchanger, or if you do not have the ash cleaner, 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 side casing of the boiler, then unscrew the 2 pcs of
wing nuts so that you can remove the metal plate. Using a cleaning tool, remove
the ash out onto the 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. Brush
the fan flaps carefully to check that the fan propeller is not clogged. If it is not
firmly attached, tighten the lock nut that holds the propeller on the fan shaft.
After cleaning, be sure to bring the boiler back to its original state. So close all the doors, screw the cleaning plate back
in, tighten the fan in an airtight manner, and make sure all the components (chamottes, cover plates in the filling shaft,
turbulators, cleaning flap) are in the right place.
