with respect to the disk. It must be pointed
out that, if perfect centering with respect to
the disk is not obtained, bad combustion and
excessive heating of the head could occur
which would result in its rapid deterioration. A
control can be carried out by looking through
the spy holes situated on the back of the bur-
ner; then tighten home the screws that lock
the combustion head in position. The distance
between the disk and the nozzle, regulated
by the manufacturer, must be reduced only
if the atomized fuel cone coming out of the
nozzle wets the disk and fouls it up.
