INSTALLATION

BOILER PLATE (A)
Drill the combustion chamber locking plate as
shown in (A). The position of the threaded holes
can be marked using the thermal screen sup-
plied with the burner.
BLAST TUBE LENGTH (B)
The length of the blast tube must be selected
according to the indications provided by the
manufacturer of the boiler, and in any case it
must be greater than the thickness of the boiler
door complete with its fettling.
For boilers with front flue passes 1) or flame
inversion chambers, protective fettling in refrac-
tory material 5) must be inserted between the
boiler fettling 2) and the blast tube 4).
This protective fettling must not compromise the
extraction of the blast tube.
For boilers having a water-cooled front the
refractory fettling 2)-5)(B) is not required unless
it is expressly requested by the boiler manufac-
turer.
SECURING THE BURNER TO THE
BOILER (B)
• Create a suitable hoisting system by hooking
onto the rings 3)(B), removing the fastening
screws 7) securing the cover 8) first.
• Slip the thermal protection (standard equip-
ment) onto the blast tube 4) (B).
• Place entire burner on the boiler hole
(arranged previously, see fig. (A), and fasten
with the screws given as standard equipment.
The coupling of the burner-boiler must be air-
tight.
ACCESSIBILITY TO THE INTERIOR OF
THE COMBUSTION HEAD (C)
• Open burner at hinge as illustrated in fig. C
after releasing the tie rod of the head move-
ment lever 1) and removing the 4 fastening
screws 2).
• Disconnect the wire 3) from the electrode.
Disconnect the tube of ignition pilot 6).
• Unscrew the under part of the elbow 4) until it
comes free of its slot.
• Extract the internal part 5) of the combustion
head.
