APPLICATION OF THE BURNER TO BOILER

The dimensions of the gas adduction pipeline should be in function with it's length and with gas delivery according to UNI regulations; It
must be perfectly hermetic and adequately tested before the burner is general inspection. It is indispensable to install a suitable pipe union
in the pipeline, in proximity to the burner, to allow for easy disassembly of the burner and opening of the boiler door.

WITH SLIDING FLANGE:
- Fasten flange (B) to the boiler with n°4 screws (D) placing the insulation card (E);
G
- Insert burner into flange / boiler and tighten screw (A) with nut (C).

The burner is equipped with a moun ting flange which slips on the
I
burner head. When applying the burner to the boiler, it is necessary
to correctly po sition the flange so that the burner head enters the
S
furnace to the extent spe cified by the boiler manufacture. When
the burner has been correctly fa stened to the boiler, proceed with
H
con necting in to the gas pipeline.
The DUNGS mod. MB... valve in cor porates a filter and a gas pres-
sure stabilizer and, therefore, only a cut-off cock and an anti-vibration
joint have to be fitted onto the gas adduction pipeline. Only if the
gas pressure were above the maximum value allowed by regulations
(400 mm. W.C.) would it be necessary to install a pressure reducer
on the gas pipeline outside the heating plant. We advise installing
a bend directly onto the burner gas ramp before applying the remo-
vable fitting. This layout makes it possible to open the boiler door,
if there is one, after the fitting itself has been opened. The above is
clearly illustrated in the following drawing (see BT 8871/GB).

DESCRIPTION OF OPERATIONS

By closing the main switch, and if the thermostats are closed, voltage will reach the control box and, after a short time, the burner will start
up according to its pre-established programme. The fan motor will then be turned on and, when it starts functioning, it will bring about a
pre -washing of the combustion chamber. Subsequently, ignition is connected and, after three seconds, the safety valve and the operating
(main) valve will open. The flame appears in this way and, detected by it's own control device, it permit the continuation and completion
of the ignition phase. In the case of flame failure, the control box activates a "safety shut down" within two seconds of the opening of the
gas valves (operating and safety). When there is a "safety shut down" the gas valves are immediately re-closed. To unblock the control
box from the safety position, push the red button on the control panel.
