KFD stove must be installed on fireproof surface. If stove is going to be placed on wooden
floor or similar combustible surface, it must be preserved with high temperature (fire)
resistant material. Floor must be preserved under and around the stove.
Local regulations in exact country have the primacy of information presented in this
manual.
All local standards and regulations regarding to distance of the wall and exhaust pipe.
2.2 Chimney
After stove installation the stoves air outlet must be connected with exhaust gas pipe. This
connection should be made with attested pipe which can be used into solid fuel fireplaces. Its
diameter should match the air outlet diameter. If there is any need of reducing this diameter
use proper reduction connectors. Connection between reduction and the stove must be
sealed. The last phase of connecting the stove with the chimney is assembling the
connection pipe with the chimney.
The chimney must have at least as much air as you need for a normal combustion of the
appliance and the ventilation of the place. Respect the UNI 10683 norm relative to the
ventilation openings.
Basic requirements for chimney pipes, which are used for stove connection are:
- Chimney pipe must have round cross-section area,
- It should be heat isolated and waterproof, made of materials which are resistant to
high temperatures, exhaust emission products,
- It cannot have any reductions or deviations bigger than 30
º,
- For rectangular cross-section
the bigger side ratio should not be higher than ½,
- The minimum height of chimney pipe should be 4 meters counting from the place
where fireplace is connected into it,
- It should have washout which allows to gather and remove all remaining of exhaust
process,
- Too big cross-section of the chimney pipe might cause problems with the way how the
device works,
- Too small cross-section area of the chimney pipe might greatly reduce the devices
draft and make it fume.
The under pressure into chimney should be around 10-12 Pa. It should be measured during
the work of the stove. When the under pressure is more than 17 Pa, installation of the
moderator should be considered to lower and stabilize it.
