7.5. Firing with brown coal and lignite
You can keep secondary air damper fully opened to achieve good combustion and better
flue emissions.
7.6. Stand-by
You can slow-down the combustion by
1.
Decreasing the set temperature on the thermo-regulator
2.
Closing the secondary air damper fully
3.
Closing the flue damper fully.
WARNING
•
Your boiler does not switch pump on and off automatically. That is why, you should keep the pump
switched on, when the boiler temperature is above the cold water temperature or there is fuel firing
inside the combustion chamber. Never switch the pump off unless the fire is completely put off.
•
Never let the boiler water temperature reach high values sharply with leaving the pump switched
off. In this case, the instant cold water delivery to the very hot boiler may result in cracks on boiler
body due to high thermal energy.
•
If the thermo-regulator does not operate properly, shift its setting step by step according to your
comfort conditions
7.7. Lack of chimney draught
If there is lack on chimney draught or there is no draught at the chimney (such as badly built, un-insulated,
blocked etc.) you may face combustion problems (no fire, excessive smoke, condensation due to cold flue
gasses). In this case, we strictly recommend you to have your chimney controlled by an expert, and fix any
irregularity. Your boiler has been designed for natural draught principle, and that is why, chimney
installation is very important.
