CLEANING THE HEAT EXCHANGER
The heat exchanger must be cleaned from soot and deposits, to preserve heat exchange capacity.
Clean it at the end of each heating season or more often, depending on usage.
Start-up defects of the burner could be due to the presence of soot inside the heat exchanger, obstructing the exhaust
gas line.
The accumulation of excess soot could depend on faulty draught, poor quality fuel or lack of air in the burner.
To clean the heat exchanger, proceed as follows.
FLUES (10)
Remove the rear panel, flue connection (8) and the 2 covers of rear fume box (9).
Clean the pipe interior (10), after removing the turbulators.
Collect the soot at the back.
Before reinstalling the 2 covers of the fume box, check that its seals are intact; otherwise, replace them with similar seals
(with the same code).
Remove the pipe on flue connection (8) and clean rear fume box (9).
COMBUSTION CHAMBER (11)
Remove the burner from its plate (4).
Clean external walls for soot and deposits.
