Installation Installation Notes on safety for the installation After carefully cleaning all around the area where the burner will The installation of the burner must be carried out be installed, and arranging the correct lighting of the environ- by qualified personnel, as indicated in this manual ment, proceed with the installation operations.
For boilers with front flue passes 1)(Fig. 15 on page 18) or flame inversion chamber, a protection in refractory material 5) must be RS 810/M BLU inserted between the boiler fettling 2) and the flame funnel 4). Tab. H This protection must not compromise the extraction of the blast tube.
Installation Securing the burner to the boiler 20162054 Prepare a suitable lifting system using rings 3)(Fig. 15). Fit the heat insulation supplied onto the blast tube 4)(Fig. 15). Fit the entire burner onto the boiler hole prepared previously (Fig.
Installation 5.10 Combustion head adjustment In order to optimise performance, the burner is equipped with a variable geometry combustion head which operates on the basis 20162133 of the delivered output. According to the same rotation of the air servomotor, it is possible to change the combustion head opening by moving the lever 2)(Fig.
Installation 5.11 Gas feeding Explosion danger due to fuel leaks in the pres- MBC “threaded” ence of a flammable source. Precautions: avoid knocking, attrition, sparks and heat. Make sure that the fuel interception tap is closed before performing any operation on the burner. The fuel supply line must be installed by qualified personnel, in compliance with current standards and laws.
