Yes mate. Twist to the right and you should feel a slight ‘click’ and it will stop. Both plugs should face the same way as the one on the left. 

Ive turned it all the way to the right until it is unable to turn anymore. There was no click. It now looks like this - Is this ok?:

No mate. It should mirror the one on the left. It had a little lug on it and that lug should sit in grooves at the top. When the lug is in the groove it should sit like the one on the left is now.

Looks like that's the problem - there is no lug on the right side dial.

I have just dialed it back to match the same position as the left side dial. I am convinced it is not doing anything as it feels very loose when being turning clock and anticlockwise

Probably snapped off mate. You can get new ones here if inclined. 

DON’T touch the one on the left.

Thanks for that mate. Question i had was if I leave that right dial without its lug, in the same position as the left dial, would that not work? or must it be firm and clicked?

Curious also what it does. 

I nearly turned the other one but glad I didnt.

It won’t do anything really, and it will most likely work but it’s not exactly right and it’s not secure. (I realise it’s not going to be touched) They’re flue sampling points for checking the integrity of the flue with an analyser. The left one is for the inner flue (so where the CO is) and is arguably the most important. You don’t want to mess with that. 

The right one is just the combustion air, you can use this point to check if the flue integrity and seals are good by analysing that air to see if it’s mixing. 

If I was at your boiler I’d change that right hand point and as they come in a pair I’d do them both.
