10.3.3 Maintenance of the flue gas system
If there are horizontal sections, it is necessary to
check and remove any deposits of ash and soot
before they obstruct the passage of fumes.
The incrustations inside the flue affect the
optimum forced draught. When they reach a
thickness of 5-6 mm, with high temperatures
and sparks, they can ignite with easily imaginable
consequences both for the flue and for the house.
In the event of failure to clean or inadequate
cleaning the appliance may have operating
problems including:
• bad combustion;
• blackening of the glass;
• blockage of the burn pot with accumulation of
ash and pellets;
Fig. 37
• deposit of ash and excessive deposits on the
exchanger with consequent poor performance.
