General 4. INSTALLATION Acceptance inspection Ensure that everything is delivered and that there is no transport damage. If there is anything wrong with the delivery, please report it to the supplier. Any transport damage should be reported to the forwarding company. Preparations for installation Ensure that the size and capacity range of the burner are suitable for the boiler.
General Burner installation Hole pattern Check that the hole pattern on the boiler matches the pattern on the burner lange. Flame head (160)* 165 (226)* 254-295 (160)* 210 (226)* 254-295 The hole pattern can be reduced if the burner pipe is itted from the front and the heels in the lange are ground off.

General Nozzle assembly regulation – fixed brake plate Nozzle assembly regulation is used to achieve the most favourable pressure drop possible across the brake plate. Nozzle assembly regulation should be adjusted for Stage 2 output. Adjustment Adjust to the desired position on the scale (A) using the set screw (B)(tur- ning anti-clockwise reduces the pressure drop and moves the brake plate outwards).

General 6. MAINTENANCE THE BURNER Servicing the burner device Removal and fitting Turn off the main power switch and disconnect the Eurostecker connectors from the burner. Undo the nuts (E) and pull out the burner body on its guides. Undo and remove the brake plate from the oil pipe.
General Servicing the air damper Removal and fitting Turn off the main power switch and disconnect the Eurostecker connectors from the burner. Undo the nuts (E) and pull out the burner body on its guides. Remove the intake grille from the air intake. Release the damper motor.
General Replacing the oil pump B55/B65 Removal and fitting Turn off the main power switch and disconnect the Eurostecker connectors from the burner. Disconnect the oil hoses from the pump. Undo the screws (J) and pull out the oil pump. Measure the distance between the pump mounting and the pump coupling (K).

General Function The pump gear (1) draws oil through the pump suction port (5) from the tank through the ilter in the pump and transports the oil to the valve (6) which controls the oil pressure to the nozzle. Oil that does not go through the outlet (7) to the nozzle will be bypassed (2) through the valve (6) back to the return port (8) on the pump.
