- The burner power should be selected according to the building heat requirement, and not according to the boiler size.
- Boilers are usually oversized. There is a common opinion among the installers that power size calculator of 10 kW per each 100 m2 of area should be used for the heating equipment. That calculator was appropriate for the non-insulated buildings constructed according to traditional technologies.
- It should be remembered that the burner is equipped with the power modulation system and its current power is matched the heat requirement of the boiler.
- The chimney draught should be min.15 Pa when the boiler works. The chimney should be airtight and made of heat resistant materials. (The system chimneys with the ceramic insert are recommended). Spacing between the burner hearth and the boiler shell should be min. 150-200 mm.
- The pellet burner is installed in the boiler door or at its side – instead of the retort burner.
- It is the best to install the burner in the boiler door in such a way that the burner is opened together with the door. If the door frame width is sufficient, the installation is usually performed centrally in the door. However, if its width is insufficient, the burner axis is to be moved towards the hinges, which significantly increases the space needed to open the burner together with the door.
- However, if the asymmetric installation makes it also impossible to open the door freely, you can use the flange receding the burner to avoid the burner hearth collision with the door frame.
- Mark and cut a hole in the boiler door for the new burner.
- Drill mounting holes in the boiler door to fix the burner to the door.
- Clean and environmentally-friendly fuel
- Automatic ignition
- Heating system does not require reconstruction
- Investment is not expensive
- It is easy to return to the old system
- Possibility of installing the “right” pellet boiler in future
- Not so efficient as the right pellet boiler
