Page 5: Installation Of Flange
9. Installation of flange The boiler connection plate must be prepared for the connection dimensions specified in "Boiler Connec- tion Dimensions". The flange gasket can be used as a marking template. First of all, loosen the size 17 nuts (2) and the cap nuts on the guide rods. -
Page 6: Inserting The Nozzles
12. Inserting the nozzles After removing the two M10 nuts (spanner size 17) the burner can be drawn back on the guide rods. It is now in the servicing position. Undo the screw and withdraw the flame ring forwards. Unscrew the plastic dust screw from the nozzle holder. When doing so, it is essential to ensure that the sealing face is not damaged. -
Page 7: Adjusting The Nozzle Assembly (Dimension "A")
14. Adjustment of the nozzle assembly (dimension "A“) The dimension "A" indicates the position of the nozzle assembly and flame ring in the burner blast tube taper. With the aid of the presetting table the burner can be set to the relevant output. In the case of boilers with a higher/lower furnace pressure, dimension "A"... -

Remove the return pipe and connection fitting. Uns- crew the bypass plug from the return pipe connec- tion and seal off with a plug. The intake volume of the pump is then the same as the nozzle flow rate. 1 = feed line 2 = return line 3 = nozzle output 4 = pressure adjuster... -
Page 10: Air Flap Positioning Motor
Upon completion of the connection work check the wiring and briefly actuate the motor contactor with an electrician's insulated screwdriver to check the direc- tion of rotation of the burner motor (not on the star-del- ta version, though). The direction of rotation is correct if the fan turns to- ward the boiler (see the arrow on the motor flange). -
