Nest Thermostat Combi Boiler (Glow-Worm) Wiring

I've just got the 3rd Gen Nest and followed the wiring diagram, but somethings not right as the way they have it drawn it will not provide permanent live to the boiler.

Can anyone help with explaining whcih wires should go where for my boiler? its the Glow-Worm Ultracom 30cxi.

It's driving me up the wall!

Thanks for any help.

Hi Mark,

Did you ever get this sorted? I've been searching around and I am in the same boat as you, there's very little information about this particular boiler and Nest out there.

Thanks
