5 Maintenance and servicing
Like all technical equipment, your Wood Combustion Water Boiler should be maintained and serviced
regularly. Depending on the cleaning carried out, varying intervals apply. Thorough servicing should be
carried out in particular before longer periods of inactivity, e.g. the summer holidays.
We recommend concluding a maintenance agreement with your heating technician.
5.1 Daily cleaning
Before each daily heating procedure the surplus ash must be removed from the feeder chamber. To do
so, lift the turbo-disk from its position and brush the ash with a glove or a brush through the hole down
into the ash tray. Make sure that the secondary air vents in the swirl chamber and the electric ignition
are not blocked. Caution: Ash and pieces of charcoal should not be forced through the burner hole. This
could cause damage to the nozzle. Do not use a vacuum cleaner to clean the feeding chamber, as the ash
could possibly still contain glowing embers. To improve the heating-up process, we recommend you to
leave some ash in the feeding chamber. Then remove the ash tray from the boiler and brush the lower
bars with the enclosed cleaning device. Finally, the ash can be disposed of. If you only burn naturally
grown wood, the ashes are ideal for use as garden fertilizer. When replacing the ash tray, make sure that
this is completely pushed in as far as it will go.
The ash sieve must be fitted, as shown in figure 11 .
5.2 Monthly cleaning
1. Turbo-burner
Once a month the turbo-burner must be cleaned. Remove all burner parts from the feeder chamber
and remove the ash.
Figure 13: Secondary air vent
Also check the primary and secondary air vents in the feeder chamber. The Tar can be removed
easier if the boiler wall is still warm.
2. Air nozzles
In order to check the air nozzles, the air duct lid must be removed. Take the red casing lid off.
