An example of the chimney selection:
- boiler output: 25 kW
- Fuel: wood logs, wood pellets
- required useful chimney height: H=8 m
- required inner chimney diameter: 18 cm
- boiler output: 35 kW
- Fuel: wood logs, wood pellets
- required useful chimney height: H=8 m
- required inner chimney diameter: 20 cm
- boiler output: 45 kW
- Fuel: wood logs, wood pellets
- required useful chimney height: H=8 m
- required inner chimney diameter: 22 cm

At connecting a boiler to the chimney, flue gas tubes and elbows must not pass behind the fan since in
that case the cleaning and maintenance will not be possible. An example of
incorrect
position of flue
gas tubes and elbows in relation to the fan is presented at the Figure 4.
