BURNER CONNECTION TO THE BOILER
The gas supply pipe must be suitably sized for the pipe length and gas output according to the UNI Standard. It must be perfectly airtight
and properly checked before testing the burner. It is essential to install on this piping, near the burner, a suitable fitting to allow an easy
disassembly of the burner and/or the opening of the boiler door.
WITH SLIDING FLANGE:
• Fasten flange (B) to the boiler with the 4 stud bolts (D) placing the insulation card (E);
• Insert burner into flange and tighten screw (A) with nut (C).
The burner is equipped with a sliding coupling flange on the combustion
head. When applying the burner to the boiler, it is necessary to
correctly position the flange so that the combustion head enters the
furnace to the extent specified by the boiler manufacturer. 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 implementation will make it
possible to open the boiler door after opening the union.
