Taking care not to touch the PCB components, disconnect the electrode lead, earth lead, mains power cable and the main sensor harness from the board. Re-engage the
fan protective cover.
3.
Disconnect the plug from the gas valve and undo the nut on the gas inlet pipe at the base of the valve.
4.
Remove the gas assembly from the boiler by releasing the over-centre catches that secure it to the heat exchanger.
5.
Remove the screws securing the gas valve. Remove the gas valve by lifting it from its seat and pulling it downwards.
6.
Using the special tool provided, remove the 4 T20 Torx screws securing the burner manifold and set the manifold aside.
7.
Fit the burner manifold to the new fan and PCB assembly using the new seals and screws provided in the kit. Do not over compress the manifold gasket or use any grease.
Check visually that the gasket is correctly in place.
8.
Replace the gas valve ensuring new O ring seals are greased prior to replacing the pipe.
