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 replace, its maximum total structural height

counting the connection pipe is 5 metres.

The replace’s structure also aects 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 replace’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 conrmed with the responsible of-

cials and the replace’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 ne-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 oor may be raised for instance with

a cast concrete block beneath it, if possible, or some other suf-

ciently 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 o its upper end.
