Troubleshooting: Check the backfilling of the burner grate,
burner combustion chamber, boiler combustion chamber, flue
gas passages, backfilling of the flue and chimney, check if the
burner grate is properly set in the burner (check that the burner
grate is not set ON the electric heater – this is valid for CPPL
14 – 50), check if the pellets are too humid, inadequate
dimensions or pellet quality (for this burner setting the diameter
6 mm), possible hole in the flexible tube, to big pellet supply
(too low fan's rpm).
