IMPORTANT
- If it is necessary to open the door of the furnace,
let it cool before opening it to avoid thermal
shocks to refractory lining.
- The rear factory material of the door can show
cracks after a short time of operation; this how-
ever does not reduce its insulation capacity nor
jeopardise its lifespan.
The door is hinged and fixed according to the indicated diagram:
In these cases, the two hinges on the left are normally used as
rotation hinges (from right to left), while the two on the right are
used as closing hinges.
It will be exactly the opposite when the door is opened from the
left to the right.
To invert rotation, just move
the lock nuts of the door.
At the first start-up, to avoid damaging the
refractory insulation, operate the burner at
minimum capacity or, if this is not possible,
cause frequent stops to gradually warm it
and obtain its "cooking".

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.
e. If hole enlargement is imprecise or increased for eas-
ier assembly, take care, after assembling the burner,
to completely and carefully fill the free space between
blast tube and refractory of the front door with the ce-
ramic fibre supplied.
f. In the presence of adapter flange for door/burner cou
-
pling, make sure the flue gas seal gaskets are mounted
on both coupling surfaces.
g. Black lead the burner fixing screws to facilitate subse
-
quent removal.
