1.2 Chimney
Once the insert is placed correctly, the outlet stub pipe of the insert ought to be connected to
the chimney by means a respective duct with the required certification, allowing application in
solid fuel furnaces. The angle of connection to the chimney ought to be
app. 45°
(figure 3
–
do not use a 90° elbow), and the connecting duct ought to have a diameter corresponding to
diameter of the stub pipe of the combustion gas outlet. If the diameter needs to be reduced,
use appropriate reducer couplings selected in compliance with the diagram (figure 21).
Use of a flexible connecting pipe eliminates the
“insert movement” phenomenon due to
tensions caused by thermal expansion if immovable connection elements are used.
Moreover, if immovable connections are installed, thermal compensation of the expanding
pipe needs to be insured and ducts must have inspection holes allowing access through
openings in the fireplace enclosure (e.g. grids in the hood).
KFD ECO inserts require installation of an additional reduction on the stub pipe of the
fireplace insert, depending on the kind of connecting pipe used for connecting the fireplace
insert. The reducing element is to be fitted with the smaller dimension inside the stub pipe of
the fireplace insert. Next, the flexible connecting pipe is to be placed inside the upper part of
the reducing element. The reducing element must not be based on the axle of the chimney
