I over filled my vokera boiler which now sits on 3.4 bar. How do I let the water out?

This worked for me
Under boiler left hand side near front there is a hole through which you can see a red plastic nut. In front of this is a small dangling plastic tab, pushing this tab towards the front of the boiler will release pressure from the system as long as you hold it open. Please ensure no-one is near the pressure relief outlet (which is normally piped outside the house) when you do this.

Not that anyone will read this but I overfilled mine. Bled the radiator and it now sits at 1.5 and seems to work. Thanks everyone for taking time to answer

If you use this valve to let water out, chances are it will not seal again!! Ask me how I know.............

If you can get 3.4 Bar on the pressure gauge then your pressure relief valve is screwed. It should blow off at 3 Bar. It is a crucial safety device that is fitted to every combi , mains pressure boiler and mains pressure hot water cylinder. If you'r worried about a gas leak you should worry more about a boiler you can run at 3.4 Bar cold.

Every system should have a drain valve on it. Check round the pipe work to see if you can find it. Either that or open the bleed screw on one of the radiators and take the excess out that way.
