Clean the convective ducting of the boiler as follows:
loosen the special fastening nuts used for tightening the lid of the convective ducting of the boiler and
carefully remove the lid. Practical experience shows that in some cases, the seal may not adhere to the
convective section plates making it difficult to remove the lids. Be careful not to damage the seal bead and
replace it if needed.
