RECOMMENDATIONS
The fl ue must be built according to good practice, the most impor-
tant elements of which are as follows:
- Minimum height (distance between connection and top of
chimney stack) will be 4 m.
- Section: chimney: Ø 200
air outlet: Ø125
Min 0,4 m
- The fl ue must be heat insulated.
- The chimney outlet (stack) and its location are very important; it
is absolutely necessary that the outlet has a cowl to prevent rain
reaching the fi replace. Ask advice from a chimney maker (any device
contracting the section of the outlet must be avoided). The chimney
outlet must be located away from areas aff ected by wind.
- The presence of obstacles near the chimney outlet must be taken
into account.
- An individual fl ue does not have more than 2 catings
(i.e. changes in direction). The angle of these can-
tings with the vertical generally speaking should not
exceed 20°, or 45° for a smooth metal fl ue.
- The fl ue must allow recovery of soot (sweepable).
- Only connect one appliance per fl ue.
FOR AN EXISTING FLUE:
It is essential to check, in addition to air tightness, emptiness and overall
stability,
the compatibility of the fi replace and if necessary, line the fl ue, or
even modify the chimneystack.
