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 disas-
sembly 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);
- Insert burner into flange / boiler and tighten screw (A) with nut (C).
The burner is equipped with a mounting flange which slips
on the burner head. When applying the burner to the boiler,
it is necessary to correctly position the flange so that the
burner head enters the furnace to the extent specified
by the boiler manufacture. When the burner has been
correctly fastened to the boiler, proceed with connecting
in to the gas pipeline.
The DUNGS mod. MB... valve incorporates a filter and a
gas pressure 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 removable 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.
