- if possible, all the chimney section should be vertical – avoid horizontal sections as well as bends
of the chimney pipe, if necessary (e.g. two bends in case the pipe is run through the wall or
window, then the maximal deflection angle amounts to 45°, the minimal chimney height should
be increased up to 7m
- the minimal chimney flue draught 16Pa at nominal heating power
- the device may not be connected to the joint exhaust fumes discharge system
Mounting the exhaust fumes discharge system, it is recommended to avoid horizontal sections of
the chimney pipe system. In order to ensure the free gas outflow, the angle of the possible pipe bend
should not be greater than 45°. The chimney outlet must be higher than the roof top.
The places where it runs through the ceiling, walls or roof must be insulated to avoid fire hazard. It
is recommended to use the dual wall insulated chimney pipe in all places where there is a possibility
of the touch contact, as well as outside the building, to ensure good draft and prevent condensation.
Do not place any materials nearby the furnace, even the non-flammable ones. Ensure permanent
access or air, necessary for the proper combustion process.
