3.9 - ASSEMBLING THE BURNER
ATTENTION!
The seat of the burner blast tube must be
as precise as possible to avoid flashbacks
or heat returns that would make the burner
connection plate red hot.
a. If hole enlargement is imprecise or increased for easi-
er assembly, take care, after assembling the burner, to
COMPLETELY and CAREFULLY FILL, with the ceramic
fibre supplied, the free space between blast tube and re-
fractory of the front door.
This prevents overheating of
the door which would otherwise irreversibly deform.
For the burner installation, the electrical connections and the
adjustments required, consult the instruction manual of the
burner itself.
Check that the correct burner has been chosen for the genera-
tor, checking the technical specifications of both.
Firmly fasten the burner to the door using
the fixing plate so that the flame is parallel
and centred in the furnace; otherwise, com-
bustion anomalies may occur with the risk
of seriously damaging the generator.
If the burner is provided with air intake, connect it with a rubber
hose to the intake on the flame indicator: in this way the glass
will remain clean.
If the cooling tube is not connected to the
warning light, it could cause the blackening
and breaking of the sight glass.
If the burner is without air intake, remove the intake on the
flame indicator and close the hole with a R 1/8 cap.
The fuel connections to the burner must be positioned so that
the generator door can be opened completely with the burner
mounted.
The flexible fuel connecting tubes must be
long enough to allow opening the door with
burner at 90°.
b. In the presence of adapter flange for door/burner cou-
pling, make sure that the flue gas seal gaskets are
mounted on both coupling surfaces.
c. Black lead the burner fixing screws to facilitate subse-
quent removal.
Fill the free space with the
ceramic fibre supplied
