For boilers with front flue passes 1)(Fig. 12) or flame inversion chamber, a protection in refractory material 5) must be inserted RS 1000/EV FGR M 20 between the boiler fettling 2) and the blast tube 4).
Installation Securing the burner to the boiler Prepare a suitable lifting system using rings The seal between burner and boiler must be 3)(Fig. 12). airtight. WARNING Insert the thermal protection supplied with the blast tube 4). Insert the entire burner on the boiler hole, previously fitted, as in Fig.
The selection of the hole to be used is determined based on the maximum output requested, as illustrated in Tab. I. In the factory, the adjustment is adjusted for the minimum stroke (hole 0, Fig. 14). Output (kW) Leverage hole RS 1000/EV FGR RS 1200/EV FGR 1100 1500 20133583 2200 2500 Fig.

Installation 5.12 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.
