BURNER CONNECTION TO THE 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.
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, connect it to
the gas pipeline.
The DUNGS mod. gas valve MB... valve incorporates a filter and a gas
pressure stabilizer, therefore, only a cut-off valve and an anti-vibration
joint have to be fitted onto the gas pipeline.
Only if the gas pressure is higher than the minimum level permitted
by the Standards (400 mm A.C.), a suitable pressure reducer
must be installed on the gas pipeline outside the heating plant.
We recommend installing an elbow directly on the burner gas train
before applying the removable coupling.
This layout makes it possible to open the boiler door, if there is one,
after the fitting itself has been opened. All that has been described
so far is illustrated in the following drawing (see BT 8871).

DESCRIPTION OF OPERATIONS

By closing the main switch, if the thermostats are closed, voltage will reach the command and control equipment and, after a short time,
the burner will start up according to its pre-established program. 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 activates 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 3
seconds of the opening of the gas valves (operating and safety). In "safety lock-out" mode the valves are closed again immediately.
To reset the equipment from its safety position, press the release button on the equipment.
1) Lock the flange B on the tube of the burner via
2) Position the insulating seal E on the tube,
3) Finally, fix the burner to the boiler via the 4 stud
