Burner Calibration
First burner
As long as the BT PID temperature has not yet been reached, the first burner remains switched on and the second burner remains switched off.
Second burner
When the BT PID temperature is reached, the first burner switches off and the second burner switches on.
Start the roasting machine, adjust the airflow, and turn on the burner.
Now set a temperature for the BT PID. For example, 110°C. Press the arrows on the temperature display to set the temperature accordingly.
Then wait until the set BT-PID temperature is reached and the first burner switches off and the second burner switches on.
Now the flame must be adjusted so that it does not go out when switching to the second burner, but is also not too large. The adjustment is made using the small screw at the rear of the machine. Turning clockwise reduces the gas throttle. Turning counterclockwise increases the gas throttle.
After making the adjustment, check the setting at the charge temperature.
Burner Installation Cleaning
To clean it, you will need a long hexagon socket wrench (for older machines, an open-end or ring wrench may suffice), if possible a blower or blowgun, a vacuum cleaner, and a thin needle.
Unscrew the igniter and detach the gas hose from the burner
Loosen the screws securing the burner to the bracket and then remove the burner.
Remove the screws on the burner to access the nozzles.
When cleaning the burner, make sure to carefully clean all openings, including the nozzles. If you don't have Blower or Blowgun, clean the openings of the with the vacuum cleaner. Note: Die Reinigung mit dem Staubsauger ist nicht so gruendlich, wie mit einem Blower oder Blowgun.
Nozzles can be cleaned with a thin needle. Carefully insert the needle into the holes in the nozzles and remove any deposits. Do not insert the needle too deeply, so as not to enlarge the holes.

Noozle Replacement
To replace the burner nozzles, follow these steps.
To ensure your safety, make sure that the machine has cooled down and is switched off.
Close the gas valve if you haven't already done so.
For 3 kg machines and less, disconnect the gas supply line from the burner and unscrew the igniter.
Loosen the screws securing the burner and pull it out.
Then unscrew the burner so that you can access the nozzles.
Remove the old nozzles and any remaining sealing tape.
Wrap sealing tape around the new nozzles and screw them in.
Now reinstall the burner step by step. The igniter should be 5 mm away from the burner.
