3. Connect the boiler to the mains (230V/50Hz) via a cable with plug.
4. Remove the flexible hose including the connection elbow (see Fig 6) from the top of the burner and
place it in a suitable container.
5. Press the START button ( Main menu
→ Boiler settings → Feeder Calibration → Feeder filling
) to fill
the screw feeder with the fuel from the tank. Stop the feeding of the screw feeder by pressing the
STOP button for about 30 seconds after the pellets begin to fall from the feeder into the container.
Empty the container with the pellets and return it under the disconnected elbow. Press the NEXT
button to move directly to the Calibration test (alternatively follow: Main menu
→ Boiler settings →
Feeder Calibration → Calibration test
).
6. Press the START button to start running the feeder calibration test ( Main menu
→ Boiler settings →
Feeder Calibration → Calibration test
). The feeder starts to pour the fuel into the container and a
countdown of the test is shown on the display. It is automatically terminated after 6 minutes.
7. Weigh the amount of fuel that has been delivered into the container.
8. Enter the amount (in grams) into the boiler control unit ( Main menu
→ Boiler settings → Feeder
Calibration → Test fuel quantity)
. This value determines the feeding quantity during the boiler
operation. Incorrect value will cause malfunction of the burner. Entering lower value than the actual
amount acquired during the test will cause more fuel to be delivered to the burner during normal
boiler operation. Entering a higher value than the actual amount acquired during the test will cause
less fuel to be delivered to the burner during the normal boiler operation.
The boiler feeder value for BENEKOV K14 must not be less than 4 kg/hr.
The boiler feeder value for BENEKOV K20 must not be less than 5 kg/hr.
The boiler feeder value for BENEKOV K25 must not be less than 6 kg/hr.
9. Push the flexible hose including the connection elbow back into the upper pipe of the burner.
7.2. Lighting up the boiler
1. Check the amount of water in the heating system.
2. Check that the shut-off valves between the boiler and the heating system are open.
3. Check that the circulation pump is working.
4. Clean the burner and the ash drawer.
5. Fill in the fuel store with the required fuel type
– see chapter 3. When finished
close the fuel store
properly to prevent possible fumes being sucked into the burner via the screw fuel feeder.
6. Connect the boiler to the mains (230V/50Hz) via a cable with plug.
7. If not done yet, select the manual control in the programmer to fill the screw feeder up from the fuel store.
8.
Switch the programmer on (see separate user’s instructions for operating the programmer). The
programmer evaluates the status of the boiler and lights it up. First, the fan is switched on and blows
through the burner. Subsequently, the fuel feeder is activated and the amount of fuel required is delivered
to the burner. Then an ignition spiral is activated to ignite the fuel. The ignition period is different and
dependant of the type of fuel, it usually takes about 2
– 3 minutes. When the fuel is ignited (meaning the
value of the parameter measured by the optical sensor reaches pre-set value), ignition mode ends and the
boiler enters the automatic running mode.
7.3. Running mode of the boiler
During this mode the fan as well and the screw feeder cycle are in operation. The basic information relating to
the running of the boiler is shown on the programmer display. This mode lasts till the boiler (or room)
temperature reaches pre-set value (see separ
ate user’s instructions for operating the programmer).
In case of power outage (230 V, 50 Hz) the programmer remembers its setting, when the power supply is
renewed the programmer goes back into the remembered setting.
