OPERATING INSTRUCTIONS
7.1 Starting the burner at first power connection
Switch on the power by pressing the ”On/Off” button until the display illuminates.
The display shows ”Ignite?”, use the arrow keys and select ”Yes” and confirm using ”Menu/Save”.
The burner starts firing, which takes a few minutes.
Note that the auger must be filled before the burner can be started.
7.2 Filling the feed auger
The auger is only filled when the burner or auger is new or if there are no more pellets in the pellet store.
Disconnect the tube from the burner.
Place a container under the tube.
Disconnect the incoming power cable and the cable for the auger motor and connect them together.
The auger motor starts and begins to feed the pellets up through the pipe.
Allow the auger to be fed until approximately 1 litre of pellets are in the container.
Check the start dose (7.1.1 in the menu) the dose must be approximately 3 dl, correct the feed time as necessary
(2.3). Corresponding corrections should also be made for the feed times for the different power stages.
Reinstall the tube on the burner as well as both cables to their normal positions on the control panel.
7.3 Starting the burner
Firstly, the pellets are weighed in for each power stage. Weigh in the pellets as follows:
1. When the installation is shut down, go to menu 7.1.
2.
Press “Menu” and select “Yes” using the arrow.
3.
Scroll down to menu 7.1.2 and press “Menu”.
4.
Use the arrow to select the power level you wish to weigh for, then press “Menu”.
5. Menu 7.1.2.X (X = power stage selected [1-4])
appears on the display, along with the message “Infeed time” and the
number of seconds.
6.
If you do not wish to alter the infeed time, confirm using the “Menu” button and infeeding will start at the selected
power stage.
7. When the dose is set, the pellets can be weighed in line with our recommendations (see below).
Recommended values for the pellets (may vary according to the pellet quality):
Power level 1: 340 g (approx. 6 kW)
Power level 2: 560 g
Power level 3: 780 g
Power level 4: 1,000 g (approx. 20kW)
After weighing the ejected pellets, calculate the power output as follows.
Output (kW) = weight (kg) x 4 x 4.9 (kWh/kg)
Calculation example: 0.9 x 4 x 4.9 = 17.64 kW
The above calculation is based on the energy value 4.9 kWh/kg. This value may vary slightly between different makes of pellet,
but it is usually stated on the pellet bag or can be obtained from the supplier.
After weighing, start the burner.
Switch on the power by pressing the ”On/Off” button until the display illuminates.
The displ
ay shows ”Ignite?”, use the arrow keys and select ”Yes” and confirm using ”Menu/Save”.
The burner starts firing, which takes a few minutes.
Flue gas instruments should be used to check the flue gas values.
