Page 13: Securing The Burner To The Boiler
Securing the burner to the boiler Introduction The RS 45/E BLU burner is suitable for working on both flame inversion boilers* (in this case the long head model is recom- mended) and boilers with a combustion chamber with bottom run- off (three flue gas circulations), from which the best results of low emissions are obtained. - Page 14 Installation Securing the burner to the boiler Before fixing the burner to the boiler, check from the opening of the blast tube that the probe and the electrode are correctly positioned, as in Fig. 13. If, in the previous check, the position of the probe or electrode was not correct, remove the screw 1)(Fig. 14), extract the inner part 2)(Fig.
