d Top acorn nut (for setting dim. Z only - do not loosen
after setting Z)
e Indicator adjusting plate
f Secondary adjusting plate
g Primary adjusting plate
h Copper oil line from oil valve to nozzle line
Initial Head Position
The indicator plate assembly (item
e
) markings
correspond to head position settings (
Figure 16
).
Slide the secondary adjusting plate (item
f
) toward
the rear of the burner until the number on the
indicator plate corresponds to the initial head setting
given in
Tables 4a
and
4b
for the desired
fi
ring rate
and burner (high-
fi
re).
Figure 16
shows a typical example, with a head
setting of
6
.
When the head position has been set, tighten the
bottom acorn nut (item
c
) and the spline nut (item
b
).
