Operating position

The burner is designed to work only in the positions 1,
2, 3 and 4.
Installation 1 is preferable, as it is the only one that al-
lows the maintenance operations as described in this
manual. Installations 2, 3 and 4 permit operation but
make maintenance and inspection of the combustion
head more difficult.
Any other position could compromise the correct opera-
tion of the appliance. Installation 5 is prohibited for
safety reasons.

Securing the burner to the boiler

The position of the threaded holes can be marked using the thermal insulation
screen supplied with the burner.

Length of the blast tube
The length of the blast tube must be selected according to the indications pro-
vided by the manufacturer of the boiler, and in any case it must be greater than
the thickness of the boiler door complete with its refractory.
The available lengths L are those indicated in the table below.
Blast tube short
RS 50/M MZ 216 mm
For boilers with front flue passes 13) or flame inver-
sion chamber, a protection in refractory material
11) must be inserted between the boiler fettling 12)
and the blast tube 10).
This protection must not compromise the extraction
of the blast tube. See Fig. 11.
For boilers with a water-cooled frontal, a refractory
lining is not necessary 11)-12) unless expressly
requested by the boiler manufacturer.
