2.3. CHIMNEY HEIGHT DIMENSIONING AND ExTENSIONS
The Modular Chimney’s maximum structural height is 30
metres. By structural height we mean the chimney’s own height.
Remember to account for the E3 regulations of the Finnish
building code or equivalent regulations in Your country of
residence regarding the height of the chimney with regard to the
highest part of the roof!
When the chimney rests with a non-insulated connection pipe
on top of the fireplace, its maximum total structural height
counting the connection pipe is 5 metres.
The fireplace’s structure also affects the chimneys maximum
height (see chapter 2.1 Foundation). If the chimney includes a
pipe bend element KC-17, the maximum height above it is 5 metres.
Remember the bracing. See chapter 2.9.9 Pipe bend element KC-17.
The chimney’s maximum height is determined by the roof’s inclina-
tion and shape, the fireplace’s draught requirements and environ-
mental factors (e.g. location in a valley, on a slope, next to a large
tree etc.). This height must be confirmed with the responsible of-
ficials and the fireplace’s manufacturer. At times it can happen that
the chimney’s minimum height will not produce adequate draught
conditions. In such a case it is easy to extend the chimney’s height
by adding an extension segment beneath the KC-32 end cap. Check
for the need for additional bracing (See chapter 2.2 Supports).
2.3.1. INSTRUCTIONS FROM THE E3 BUILDING CODE
Attn.! When the chimney does not pierce the roof close to the
top, add 10 cm to height for each metre of roof (80, 90, 100,
110…). (Illustration 2)
2.4. CHIMNEY HEIGHT ADJUSTMENT
The basic height comes from a suitable number of modules.
This is then fine-tuned as follows:
The non-insulated connection pipe or the support segment
(KC-03) is cut down to the required length using a metal saw
or an angle grinder. The cut end must be exactly perpendicular
to the length of the segment. The non-insulated connection
pipe can be extended with a non-insulated extension pipe.
A chimney resting on the floor may be raised for instance with
a cast concrete block beneath it, if possible, or some other suf-
ficiently stable support. The chimney must not be extended at
its upper end with a mere length of piping.
The support segment (KC-03) can be shortened by cutting the
excessive length off its upper end.
