Flue pipe
-
The flue pipe must be at least 5 metres in height. This height is measured from where it
connects to the fireplace. The flue pipe must have a minimum draught of 12 Pascal.
-
The channel must be thermally insulated to avoid condensation and to achieve a better
draught.
-
Changes in direction may be 45° maximum and there may only be two changes in direction.
-
The flue pipe must be vertical for at least 1 metre before it changes direction.
-
This fireplace must be connected to one individual flue pipe.
-
A rain cap must be fitted to prevent moisture from entering the hearth.
-
Do not install a flue pipe with a diameter wider than the one provided for the fireplace.
-
The outlet and position of the chimney on the roof surface and compared to adjacent
buildings can only be installed according to local building standards. Take factors in the
surroundings into account (trees, blocks of flats and so on).
-
See Table 2 on p.11 for the flue pipe dimensions. If the connection is shortened, 1 metre
extra must be calculated for the length of the flue pipe. For each 45° change of direction, 1
vertical metre extra must be calculated.
-
Using a flue pipe diameter which is too narrow is at the insta
ller’s risk. Also, smoke may blow
back into the room when the door is opened.
-
If there are several flue pipes or ventilation shafts in the surround space, only one flue pipe
may be connected to the fireplace and the remaining channels must be sealed.

The minimum heights indicated are for ideal conditions. A longer length may be required, depending
on the conditions. The installer must check this when testing the fireplace.
