regularly.
Cleaning the convective duct of the boiler is performed in the following
way:
Unscrew the specialized fixing nuts, which are used to tighten the lid of the
convective duct of the boiler and carefully detach the covering lid. Practice
shows that in some cases the gasket could be adhered to the plates of the
convective section, which will to difficult detachment of the lids – take care no
to damage the gasket rope, eventually it has to be replaced.
