Service after overheating
If overheating occurs, the safety valves of the boiler must open.
Make sure the boiler pump is working. In case of blackout open all the valves of the system to
let hot water out of the boiler. In any case a blackout protection UPS is recommended to be
installed on the boiler pump.
If the chimney damper is not fully opened, put it in fully open position.
All safety devices must lead to drainage! After overheating, make sure that all the water from
the safety devices has drained, and the system has filled with cold water. Check the pressure
and the temperature of the boiler.
At overheating, the safety thermostat will activate, and cut electrical supply to the fan. In that
case, you need to manually reset the safety thermostat and put the system back in function.
Unscrew the plastic cover of the safety thermostat and press the switch. Put the plastic cover
back.
Verify the causes of the overheating! If it happens again, check the installation
and function of the pumps and safety devices!

After cleaning all the ash, empty the ash box and leave the boiler clean for the next winter
season.
After long stop of the boiler, before you put in function you need to perform the following checks:
Check the condition of the electric cables and the sensors. Make sure they are not damaged.
Check that the thermometer indicates the correct temperature and all the thermostats
function properly. Make sure the bulbs are properly positioned in the case.
Make a general check of the chimney and make sure it is clean and free of obstacles.
Verify the pressure in the heating network and the boiler.
Do not empty the water of the boiler and the heating installation after the heating
season! It will corrupt all the installation and especially the boiler.
