any processing residues. Considering the high risk deriving from incorrect chemical treatments, the operations must be
carried out by
professionally qualified personnel
.
–
Before start-up, open the door and insert the turbulators completely inside the front ends of the smoke pipes, taking
care to push them inside by at least 100 mm.
–
Check that all connections are fully tightened
