INSTALLATION
THE BURNER MUST BE INSTALLED
IN CONFORMITY WITH LEGISLATION
AND LOCAL STANDARDS.
WORKING POSITION (A)
The burner is designed to work only in
the positions
1
,
2, 4 and 5
.
Installation
1
is preferable, as it is the only one
that allows the maintenance operations as de-
scribed in this manual.
Installations
2, 4 and 5
allow the working, but
make the operations of maintenance.
Any other position could compromise
the correct working of the appliance.
Installation
5
is forbidden, for safety
reasons.
All the positions require the installation of the
gas valve with coils pointing upwards, or hori-
zontal (Fig.A). Installation with the coils point-
ing downwards is absolutely forbidden.
BOILER PLATE (B)
Pierce the closing plate of the combustion
chamber, as in (B). The position of the threaded
holes can be marked using the thermal screen
supplied with the burner.
HEAD LENGTH (C)
The length of the head must be selected accord-
ing to the indications provided by the manufac-
turer of the boiler, and in any case it must be
greater than the thickness of the boiler door
complete with its fettling.
The range of lengths available, L (mm), is as fol-
lows:
The burners cannot be used on
flame inversion boilers.
It is possible to insert a protection made of
refractory material between the combustion
head 6)(B) and the boiler refractory 8)(B).
This protection must allow the blast tube to be
taken out.
Do not insert the protection in line
with the electrode unit, as this
would compromise its good opera-
tion.
