Occasionally operate the system until the pellet tank is empty and then check the
tank for any fine residues before filling it again (sawdust). If there is an excessive
amount of fine residue in the pellet tank, it needs to be cleaned.
Excessive fine residues in the screw conveyor will hinder the take-up of pellets and
reduce the heating output.
7.3. Maintenance work after 400 kg pellets or after one year
The following maintenance work must be carried out after approx. 400 kg pellets
have been burnt, or at least once a year to guarantee safe and efficient operation
of the pellet stove.
This maintenance work may only be carried out by trained personnel.
7.3.1. Cleaning the flues and the heat exchanger
2 cleaning apertures are available to clean the flues:
Upper cleaning aperture:
Remove the covers to the left and right of the heat exchanger and use the supplied
tool to clean out any deposits and contamination (Fig. 14).
Fig. 14: Upper flues cleaning aperture
Lower cleaning aperture:
Open the combustion chamber door. Remove the baffle plate (Fig. 15) located in
front of the heat exchanger on the top side of the combustion chamber. Then re-
move the burn grate, followed by the grate. You can then remove the insulating
panels attached to the rear.
Remove the sealing covers located on the left and right of the pellet chute. Use the
supplied cleaning tool to remove any deposits that may have formed in the flues
