FUNCTIONING Switching on 1) Check that the gas service tap is opened at the gasmeter and main power is on. 2) Check that pressure in central heating system is above 0.7 bar and COMPONENTS LOCATION 50 K 49 51 below 2.5 bar with the pressure gauge 18. 3) Open the gas tap 3 by turning from right to left. 12 4) The boiler is now ready to use. Hot Water 10 1) Turn selector switch 15 to position 46 cator 40 The green "power on" indi- (20) will light.

When there is a need for hot water tank reheating while the heating is on. The heating will be interrupted momentarily while tank is reheated. The boiler will switch back automatically to heating when the tank is at temperature. Note: If the boiler has been turned off for some time the first attempt to light it may result in a lockout . 22 . If this happens press the reset button 23 and the boiler will light.

REMOVAL AND REPLACEMENT OF PARTS Before removing appliance case, isolate the gas and electrical supplies. Isolate boiler from the system and drain before removing any component in the waterways. Ensure that the appliance is cool. 1. Outer Case Remove four screws in base of case 5. Ignition Electrodes Carry out steps 1 and 2 as above. Hinge down electrical box by pressing retaining tabs P on either side. P 10. Pressure Switch Remove outer case and sealed chamber front panel as in steps 1 and 2.

14. Flow switch Drain boiler as in step 12. Disconnect the electrical plug, turn the top cover anticlockwise, remove the O-ring and the brass piston. Reassemble in reverse order. 15. 3-Way valve Drain boiler as in step 12. Remove the 3 clips on the 3 way valve. Remove the clip on the exchanger flow pipe. Pull the pipe down then pull it out of the 3 way valve. Disconnect the plug from the motor. Unscrew the nut on the pipe between the connecting bracket and the 3 way valve and pull it toward you.
