If all checks are satisfactory, load the pellets into the conveyor.
With the ATMOS burner, plug the conveyor‘s lead into a regular 230V - 50Hz socket. After the
pellets start falling out of the conveyor (conveyor is full), plug the conveyor‘s electric flex back into
the socket on the burner.
Close (hang up) the air flap valve controlled by the FR124
draft controller
so that secondary air should not be suctioned into the boiler (we use it only when burning wood).
For the D20P boiler with its burner set to output ranging under 16 kW, switch the suc-
tion ventilator permanently off (by disconneting the ventilator connector in the side
hood of the boiler). When burning pellets in the boiler types D30P, D40P, D50P the
suction ventilator must be operating during all boiler‘s output modes.
Approach the boiler panel and switch on the main (green) button switch
, the burner and the ash
removal button switch (if they are installed).
When the boiler is put in operation for the first time, an installer or qualified technician should
adjust combustion of the burner with the use of a flueg asanalyzer the sensor of which is to be in
-
serted into the measurement place (opening) in the flue between the boiler and the chimney.
Always
adjust the burner in a stabilized condition, approx. 20 - 30 minutes after fuel ignition. If there is no flue
-
gas analyzer available for the boiler adjustment at the moment, you can adjust the pellet burner „roughly
by guesswork“. Set the quantity of fuel and combustion air in such a way to stop the flame (1 - 3 cm)
before the opposite wall (the flame should not touch the wall). The flames must not turn at the opposite
wall in any case. In such a case add combustion air by opening the flap of the burner fan or reduce the
fuel supply.

ret = 13 %).
After the adjustment of the burner the operation of the boiler is completely automatic, the cus-
tomer only replenishes fuel and removes ash in regular intervals.
CAUTION
- The adjustment by the flame length does not replace adjustment made with the
use of a flue gas analyzer by a qualified person. Changes of settings of the boiler and burner
may only be performed by a person that is qualified in accordance with all the valid regula
-
tions and ČSN EN standards. Before the adjustment of the burner the combustion chamber
of the burner and boiler and the chimney with the flue must be completely cleaned.
