POSITION OF ELECTRODES (A)
Make sure that the electrode and the ignition
pilot are positioned as shown in figure (A).
COMBUSTION HEAD SETTING (B)
In addition to varying air flow depending on the
output requested, the air gate valve servomotor
4)(A) pag. 4 - by means of a lifting assembly -
varies the setting of the combustion head.
This system allows an optimal setting even at a
minimum firing rate.
For the same servomotor rotation, combustion
head opening can be varied by moving the tie
rod onto holes 1-2-3, fig. (B).
The choice of the hole (1-2-3) to be used is de-
cided on the basis of diagram (D) against the re-
quired maximum output.
Setting is pre-arranged in the plant for the maxi-
mum run (hole 3).
When dealing with boilers featuring a strong
back pressure, if air delivery is insufficient even
with the damper fully open, you can use a differ-
ent setting to that illustrated in diagram (D) - do
this by moving the tie rod onto the next highest
hole numerically speaking, thus increasing the
combustion head's opening and hence air deliv-
ery.
If combustion requirements require you to move
st
spacer (1) fig. (C) onto the 1
gear and, at the same time, the hinge is on the
right, you need to fit the spacers (4) fig. (C)
supplied with the burner.
Proceed as follows (fig. C):
- first unscrew nuts (2), remove tie rod (3),
unscrew spacer (1) and position it on the hole
you want,
- screw the spacers (4) onto spacer (1) and
screw (5) respectively,
- once done, refit the tie rod and nuts.
For operation on flame-reversal
boilers, gas pipes must be adjusted
to hole position 4, see Fig. (E).

ROTATION OF FAN MOTOR

Look at the fan motor's cooling fan from the front
and make sure it turns anticlockwise.
