3.5.3 Flue/chimney
3.5.3.1 TPK and Scandpell
The temperature of the flue gas, especially at low output, may result in the formation of condensation in
the flue/chimney.
It is therefore recommended that a flue is used which is appropriate in wet conditions.
Always install the flue from the flue gas outlet from the boiler in such a way as to prevent
condensation from the chimney running back into the boiler.
Always use a draft stabilizer.
1: installation with an insulated steel flue
2: Installation with a flue fitted into an existing chimney
In both cases, a condensate drain must be fitted in the bottom of the vertical section of the flue, and the
part of the flue between the boiler and the vertical section should be insulated.
Necessary minimum chimney draft: 0.1 mbar
3.5.3.2 TPK with a burner from another supplier
When installing a burner other than a Scandpell, the same precautions should usually be taken as when
using a Scandpell.
The flue gas temperature is determined primarily by the boiler. The requirements in terms of the flue can
be deviated from only where a wood pellet burner is used that can only run constantly at high output.
The required minimum chimney draft is dependent on the burner being used.
