following rules are observed:
- check the conditions of the chimney; old
chimneys should be renovated by introducing
steel piping with suitable insulation (rock wool,
vermiculite).
- the flue gas can be discharged directly into
the chimney only if the latter has a maximum
cross-section of 15 × 15 cm or diameter of 15
cm and features an inspection opening.
For larger chimneys, suitably insulated steel
pipes need to be inserted on the inside (diameter
according to the length (Fig. 5.10.1).
Makes sure connections to brick chimneys are
suitably sealed.
Avoid contact with combustible materials (e.g.
wooden beams) and in any case insulate these
using fireproof material.
If the flues run through wooden roofs or walls,
special certified pass-through kits need to be used,
available on the market.
1) Vermiculite and/or rock wool.
2) Steel pipes.
