Specifically there is the stagnation, i.e. a slight decrease of temperature of flue gases
which is visible when re-filling of pallets is done into the furnace.
The procedure for troubleshooting 5
–
Raise the temperature of flue gases to enter the
system of the parameter F18. This way new pellet entering the combustion chamber
lowers the temperature of flue gases in a more harder way as the flame is stronger
because it had more time until the re-filling of fuel. This problem most frequently occurs
when the chimneys are poor in construction or the drought from any other reason is weak.
Possible cause 6
CAUSE 6
–
The boiler has passed the stabilization phase but it is going into modulation,
and on the display it says - Nod. If flue gases are checked, at this point, it is distinct that
they are too high.
The procedure for troubleshooting 6
–
Check whether the flap inside the boiler is in the
position, „open''. Close the flap, i.e. moving the handle on the side towards the front of
the boiler.
Possible cause 7
CAUSE 7
–
The boiler has entered the phase of stabilization, but after a while the fire is
extinguished.
The procedure for troubleshooting 7
–
You forgot to push back the ashes tray into its
compartment and to completely close the ash tray.

Introduction
When the boiler reaches the set temperature of the water in it, or the air in the room, where the
room thermostat, turns into a resting phase keeping the flame or, originally said „Standby
phase“. best example for this type of boiler is its operation at
night.
The main objective of this phase is to maintain the flame or live coals in the firebox during
several hours of standby. It is achieved through periodic turning of both the pellet conveyor and
fan in certain periods of time.
-
At the time when the boiler has reached the set temperature it enters the phase of flame
maintenance. After a certain period of time, as determined by the parameter T04 (in
minutes) the conveyor starts and fans are activated. During this period it comes to
activating of the boiler until it receives the command to start due to the achieved
temperature.
-
The duration of the process of conveyor and fan operations is determined by the
parameter t05 (in seconds).
-
During the process of the start of conveyor operation, its work is determined by period as
determined by the parameter CL09 (in seconds)
