If... Then... And...
the adjustment ring is not
positioned rear enough with
a fuller load there is too much pressure
drop in the combustion head the igniton is poor OR
improper burning due to
inadequate amount of air
(high CO-content) OR
flame tear-off from the

to fuller load
the adjusment ring is too rear
with a lesser load there is not enough pressure
