Boiler Biomax works with forced draft and is under the influence of two fans, but we also need
to respect the rules for the selection of the chimney as it is a boiler with mild potpritiskom in
fireplace to another fuel, such as fuel oil, for example. Empirically, based on our experience
cross-section of the chimney should be at least equal to the diameter of the flue that. for
Biomax23 it is 130mm for the Biomax 35 to 160mm.
Doing so may cause a malfunction, particularly during ignition mode and solid fuel
.
If the boiler Biomax is working only on pellets are possible and much less of these chimneys.
It is recommended that the diameter of the chimney is at least equal to the diameter of the flue
has a minimum height of 7 to 8 feet, depending on the coverage of the chimney other high
buildings next to it. Optimal placement of boiler chimneys on such rights to the exit connects the
center of flue gases from the boiler and the chimney connection center is a gentle ascent (up 3%).

If possible, arcs should be avoided, but if not possible, then the maximum number of arcs is 2.
The fume channel from the boiler to the chimney, should desirebly be insulated, specially if it
has arcs and longer sections.
On the smoke pipe, approximately 100mm from the flue outlet from boiler, a hole should be
drilled and a temperature gauge should be mounted for flue gas temperature measurings. Without
information about the temperature of flue gases there isn’t the automatic mode of the boiler.
The chimney itself should be made of ceramic pipes, and around them there should be the
insulation of 3- 5cm thickness and the outer layer is of the bricks or special elements. If the
chimney is not from ceramic pipes but of bricks, the light opening area of such chimney shall be
30 % higher than the surface of this ceramic pipes chimeny. Minimal sectional dimensions of
both chimneies and the minimum heights are given in table 1.
The chimney must have a door for cleaning and it must be well sealed. Chimney outlet on the
roof must be according to certain regulations. There are two cases: if the angle of the roof is less
than 12° and if the roof angle is bigger than 12 °. For angle less than 12 ° the height of the
chimney above the roof is 1 m and for the larger than 12 ° , then look at the sketch.
