• check the sealing of the gaskets;
• check the opening mechanism.
• check the wear state of the elements.
15.3.1 Servicing and cleaning the fume exhaust duct
To be performed at least once a years or every 40 quintals of burnt fuel.

In case of failure to clean or inadequate cleaning, the stove may have problems in operating properly such as:
- poor combustion;
- blackening of glass;
- poor draft with smoke entering the room.
15.4 WHAT TO DO IF THE STOVE DOES NOT WORK
15.4.1 Problems lighting the fire
• Open the primary air and the smoke register

• Check that the flue pipe is suitable for the stove being used;
15.4.2 Smoke comes out of plate
• Check that the primary air register is open
• Check that the chimney connection has no leaks
• Check that ashes and combustion residues are not clogging the discharge duct or the grille
• Insufficient draught
15.4.3 Glass gets dirty too quickly
• Damp wood: use well-dried wood (15% relative humidity)
• Check that ashes and combustion residues are not clogging the discharge duct or the grille
• Unsuitable fuel
• Too much fuel
• Insufficient draught (see connection and flue pipe)
15.4.4 Condensation in combustion chamber
• The first few times the stove is lit, it is normal for condensation to form, since the cladding materials contain humidity
• If the problem persists, make sure the wood being used is not damp or poorly seasoned
• Check that the chimney is not too large and whether the fire heats it all the way to the top;
