Advice and tips

The vents of the exchanger should be cleaned as required, at least 1x every 3 weeks, using the steel brush provided. The amount of dirt is largely affected by the moisture content of the fuel, means of operation (e.g., operation in energy saving mode – air regulators closed), and also the manner of connection to the heating system (see operating manual). The vents of the exchanger can be accessed from the combustion chamber. In fireplace stoves and inserts where deflectors are used to direct the draft, these must first be removed.

A clogged exchanger will cause excessive smoke in the combustion chamber; the smoke may even escape into the room. A layer of dirt also reduces the efficiency of the hot-water exchanger.
