Why does my Bosca SPIRIT 500 Pellet stove shut off and the #3 light flash?

If your Bosca pellet stove shuts off and the #3 light flashes, it could be due to several reasons. First, ensure the hopper is filled with pellets and the lid is securely closed. An open lid prevents pellet feeding. Also, check that the air damper isn't too far open for a low feed setting. Make sure the burnpot is correctly positioned, touching the rear wall of the firebox, and that the burnpot holes are not blocked. Remove the burnpot and clean it thoroughly. Finally, inspect the air inlet, interior chambers, and exhaust system for any blockages, following the cleaning procedures in the maintenance section.
