7.3.9 STOP - not ignited
Message about an improper boiler function in case when required combustion products temperature increase does
not occur during switching from the STAND BY mode or during electric ignition.
This condition is indicated on the display by the following script:
STOP - not ignited

7.4 BOILER OPERATION AT THE LIMIT CONDITIONS
7.4.1 Insufficient amount of pellets in the bin
Causes boiler to extinct. This is not a hazardous condition. The boiler will evaluate the fuel deficiency with a
delay. If the water temperature drops due to boiler extinction, the condition is evaluated as
STOP STATE2 chapter 7.3.5. If the fuel runs out before the boiler goes into the dampen mode and the boiler
becomes extinct during the stand by mode, the condition may be evaluated as
STOP STATE3
chapter 7.3.6
STOP - not ignited
chapter 7.3.10
Possible causes Corrective measures
insufficient amount of fuel in the bin Refill the fuel in the bin
Putting into operation:
1. Fill the feeder F2 with fuel by operating the feeder F1 (see MENU 1 Direct control).
2. Ignite the boiler by using routine electric ignition or by hand.
3. Automatic mode can be then switched on by pressing START and ENTER button.
7.4.2 Clean the boiler
This is not literally a state of failure, the control unit is reminding the operator of neglected maintenance.
If the combustion products temperature exceeds 250°C for a short period of time (regular working temperature is
below 200°C), the boiler evaluates this fact as a clogged exchanger. It is necessary to clean the boiler
immediately.
This condition is indicated on the display by the following flashing script:
Clean the boiler
An the same time, the control system will decrease the boiler output by one degree to prevent from any further
increase of the combustion products temperature. If the combustion products temperature reaches elevated
temperature again, the boiler output is decreased repeatedly.
Possible causes Corrective measures
Clogged boiler heat exchanger Complete clean-up of the boiler - see annual revision
Shortening chimney draughts cleaning period - service

Unsuitable fuel type Complete clean-up of the boiler - see annual revision.
