3.5.3 - 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; there-
fore pay the utmost attention.
