Tuning the burner
▀
Fill screw
►
Start with filling the auger by setting "FILL SCREW". The auger will run for 15 min. Put a
bucket under the outlet to prevent pellet from falling out. It is important that the auger is
filled properly, therefore it is a good idea to tap it with for example a rubber mallet during
the filling.
The fan
►
The rpm for the fan is set in the menue "FAN". The rpm is dependent upon the operation
dose set. For the best efficiency a flue gas analyzer should be used. We recommend
12% CO2 in the flue gases. You also choose if the low power option should be activated.
Which might be good if for example there is a small amount of water in the boiler.
Start dose
►
The feeding of the pellet is the most important part in the system for a good combustion
and function. Set the start dose by activating the "RUN START DOSE". It is important
that the start dose is correct and it should be controlled when the burner has been running
a number of hours. The amount of pellet fed when running the start dose should be about
3,5 dl. If the burner fails to start, the dose can be increased a bit, and if it smokes a lot
during startup it might be decreased a bit.
Operation dose
►
The operation dose is set in the menue "RUN OPER.DOSE". Weigh the pellet that is fed
through the auger and adjust the power according to the diagram below. Never run the
burner at a higher power than needed, it is harder to maintain best efficiency at higher
power.
Service
►
In this menue the settings is deciding how and when the burner should be cleaned with the
compressed air. The less time the cleaning is set to be prevented, the better. There will be
fewer times/year the burner needs to be cleaned manually if the compressor is allowed
to do the work. Here is also the maximum time set for the burner to be running before
it cleans itself. It goes into cooling phase and cleans and then startup again. When the
settings are made, set the burner to "ON", and the first start will take place if there is a
heating need from the boiler.
Doses calculated with pellet with the energy content 4.8 kWh/kg.
Power kW
Amount of fuel kg/h
If "RUN OPER.DOSE" is set, the auger will feed small doses of pellet for 6 minutes in
the same way as when it is running normally. Weigh the pellet fed to get the right power. 6
minutes is equal to 1/10 of 1 hour. If you set the burner on 20 kW it should have 410 g as
operation dose.
