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.
