LOW-PRESSURE GAS SUPPLY SYSTEM
After having correctly applied the burner to the boiler, it must be connected to the gas pipes (see BT 889). A
suitable pipe fitting must be installed on these pipes, close to the burner, so as to allow an easy dismantling of the
burner and/or the opening of the boiler port.
The following must also be installed: ball stop cock, gas filter and vibration-damping joint.
Said components must be installed as shown in our drawing.
The gas supply pipes must be sized according to the gas length and feed, and they must be perfectly sealed and
properly tested before carrying out the burner general test and inspection.
We suggest that you follow the recommendations below relating to the installation of the necessary accessories
on the gas pipes close to the burner.
1)
The gas filter must be arranged on a horizontal piping, so as to prevent possible impurities from enter-
ing into the piping during the cleaning of the same.
2)
It is advisable to install an elbow directly on the burner gas train before applying the removable union.
This allows opening the boiler port after opening the same union. What said above is clearly shown in
the following drawing.
Note: If the burner is equipped with gas valves, model SKP 70 ....., the pressure regulator needs not be in-
stalled since in its normal operation the above valve also functions as pressure regulator.
