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.
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).
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);
- Insert burner into flange / boiler and tighten screw (A) with nut (C).
