3.6 - CONNECTING FLAME SIGHT GLASS
TO BURNER
The flame sight glass is provided with a 1/8” threaded connection
(pos. 1) upon which a 9 mm pressure test nipple is mounted.
It can be used with a silicon tube to measure the backpressure
in the combustion chamber.
In place of this test nipple, which must be kept, an appropriate
fitting will be mounted to connect the flame sight glass
directly to the pressure chamber downstream the burner fan by
means of a copper tube (pos.2).
The air blown by the fan will conveniently cool the sight glass
and keep it from blackening.
If the cooling tube is not connected to the sight glass, it could
break.
ATTENTION: the flame sight glass can be very
hot; therefore pay the utmost attention.

3.5.2 - INSTALLING THE BURNER
Before assembling the burner, check the posi-
tion of the turbulators inside the tubes: each
tube must be provided with its own
turbulator and this must be positioned as
shown in the figure on page 8.
The burner must be mounted to the door of the
boiler guaranteeing perfect sealing of the combustion products.
The burner is supplied with
a piece of ceramic fiber cord which
must be placed on the blast tube of the burner to fully seal
the space between the blast tube and the slot in the door.
Make sure that no gaps remain between the blast tube and the
slot on the refractory material inside the door.
Should a cone larger than the diameter of the blast tube be
mounted, it must be removed before mounting the burner on
the support plate and put back afterwards.
With the burner mounted, check that the electric cables are long
enough to allow the door to open 90°.
For gas-fired burners, flexible hoses cannot be used for
connections. Therefore it must be possible to disconnect the
final section of the gas adduction tube by means of a threaded
or flanged joint.
