Maintenance
All interventions can only be done by contractual service organization trained by the manufacturer.
1. Disconnect the boiler from the electricity supply.
2. Close the fuel supply to burner.
3. Push the burner out from the combustion space.
4. Dismount the closing plates from the boiler drum.
5. Check the clogging of the boiler convection surfaces and clean them chemically (like by Metano Therm).
If the regular maintenance was neglected and the convection surfaces are heavily clogged apply the
procedure as follows:
-
fill all convection surfaces vents with diluted soap solution by pouring it from above;
-
let the solution effect for approx. 10minutes;
-
use a lower water pressure for spraying the convection surfaces;
-
repeatedly by applying a higher water pressure complete the convection surfaces cleaning;
-
remove thoroughly the impurities from the space of burner.
6. Check the burner nozzle clogging. In case of impurities clean it according to burner manufacturer´s
instructions.
7. Mount back the closing plates and install the burner.
8. Open the fuel supply, renew the connection to the el. network and start the boiler.
9. Check the tightness of the fuel inlet to the burner.
10. Set and adjust the boiler thermal output.
10. Defects and their elimination
The defects can only be eliminated by a trained contractual service organization which notes down the
remedy in the guarantee attachment.
If the safety thermostat keeps blocking repeatedly also the contractual service worker must be
called.
