b) the position of cut-outs in the combustion chamber
head.
NOTE:

heat exchanger in such a way that its welding seam is
positioned between 2 and 10 o clock (not upwards!)

A position change during maintenance is permissible
and affects the expected service life of the combustion
chamber positively.

between disc and burner head and will be burned at
