Using Ø8 wood pellets (7 % moisture and 17,5 MJ fuel heating value).
Fuel load combustion duration depends on fuel type, moisture, outside temperature, heat consumption.

Permanently constant draught from the boiler has to be ensured, so it is necessary to install smoke exhauster. For control of the smoke
exhauster, frequency converter and differential pressure sensor are recommended.

Dimensions are determined for a particular order at the time of
Peephole installed in the rear of the boiler is used to observe the combustion process visually.
For draught measurement in the boiler, branch pipes are installed on the both sides of the boiler, under
trimming covers, one branch pipe is used to pull a tube on, other end of the tube is led to the differential
pressure gauge installed in the control box (
see fig. 6
).
On the top of the rear wall of the boiler, smoke collector is installed, having three holes directed towards the
rear and the both sides. Flue pipe branch pipe is attached to one of the holes, selecting the direction, the
remaining two holes are covered with sooth removal lids.
