Faults and Troubleshooting
In the presence of a fault in the operation of the burner-boiler system, one should be familiar with the prob-
lems and how to solve them as described in the user manual for operation of steel hot water boiler, as well as
in such for automated pellet burner. In the following table this information is supplemented by data that will
be of assistance to the service technician.
In case of a failure, try to repair it or inform a heating specialist. As an installation user you may only make
repairs, which involve just a simple replacement of the grate.
In case of „first “commissioning of the boiler condensation of water vapour on the heating surfaces of the heat
exchanger may occur. This one-time process does not cause problems in the operation of the facility;
Operation of the automated pellet burner in modes, which exceed its heating power according to its technical
parameters, is not allowed. In the case of exceeded rated thermal power of the automated pellet burner irrev-
ocable deformations may occur in the area of the combustion chamber of the burner, which lead to its failure
– in such cases the factory warranty of the burner is not recognized by the manufacturer.
