Automatic pellet burner of series “GP” faults and repair procedures
.
EXPLANATION :
*:
the overheating of the pellet delivery pipe is most commonly due to increased
ash deposition layer on the heat exchanging surfaces on the appliance, on which
the burner is installed;
** in case of deficiency of chimney’s draught, it is recommended to ask for
service assistance in order to solve the problem – it could be possible to make
thorough cleaning of the chimney or even to make reconstruction of the
chimney, also installation of additional flue gas fan could be an appropriate
technical solution – any of these should be done by service technician as well;
