2 and 3 in nest go to 4 an 1 on the boiler.

 

[jeverall]

is that terminal block x9 on the boiler?

 

[Echo the husky]

No! X2, read the terminal descriptions!

 

[jeverall]

so is this right ?

& remove the jumper wire between 4 & 1?

 

[Echo the husky]

That will be fine, but that boiler is designed so you can take power from X2 5-Neutral and 4-Live to feed external timers.

& remove the jumper wire between 4 & 1?

Its written right there!

As far as i know doesn't the case that provides the room seal for this model have to be removed to get to the electrics, not really diy territory.

In fact it was in the news recently that a diyer didn't put the case back on the boiler correctly and /or tested it's effectiveness which led to the co poisoning of a family. The culprit was fined for £5000, could of been prison if there was a death.

I've not yet had the fascia off the boiler, but something to bear in mind thank you for everyones advice

Get in a gas safe eng to do the job

Jeverall, did you (or your gas safe eng) manage it? Where did he/she physically put the heat link? Any tips?
