COMBUSTION HEAD ADJUSTMENT
At this point of the installation, nozzle and pipe
coupling are fixed to the boiler as in fig. (C) p. 5.
The setting of the combustion head depends
exclusively on the output of the burner - in other
words, the combined output of the two nozzles
selected on page 6 is a particularly simple oper-
ation.
Turn screw 1)(A) until the notch on the sheet
2(A) is level with the plate 3)(A).
Example
RL 34/1 MZ with nozzles:
1° = 3.50 GPH + 2° = 2.50 GPH and 12 bar pump
pressure.
Find the delivery of the two nozzles in table
(A)p. 6:
25.4 kg/h (corresponding to 301 kW).
Diagram (B) shows that for an output of 25.4 kg/h
the burner RL 34/1 MZ needs a combustion head
notch regulation 3.5 approx.
Note
If the pressure in the chamber is equal to 0 mbar,
the air must be adjusted with reference to the
hatched line on the diagram (B).
Once the regulation of the head has been con-
cluded, refit the burner 4)(C)p.5 on the guides
3)(C)p.5 at approximately 100 mm from the pipe
coupling 5)(C).5, insert the electrode cables and
then slide the burner as far as the pipe coupling.
Replace the screws 2)p.5 on the guides 3)p.5.
Fix the burner to the pipe coupling with the
screw 1)p.5.
Attention
On closing the burner on the two guides it is
advisable to gently pull the high voltage wires
outwards until they are under slight tension.

FAN GATE ADJUSTMENT

The fan gate is set using the indexed selector
1)(C), after having loosened the nut 2)(C).
The first time the burner is fired, this setting
should be left as originally set by the manufactur-
er: notch 2, see fig. (C).
