Sounds like you have old mechanical programmer, look at there web site for a digital one which will probably fit existing backplate of your one.

When you say valve do you mean motorised valve?. If so is it 3 port ie 3 pipes, or 2 port ie 2 pipes, if 2 port do you have 2 of them? what make are they?.

Okay i've looked at instructions for your boiler, look underneath and you will see two plastic taps on two of the pipes which are at right angles to the pipes 1 heating pipe and the incoming water mains turn them so that they are inline with pipes until pressure has risen to 1.5 bar approx then...

Look on pipework somewhere near boiler for a filling loop. Look at faq 6.

Yes 90 degree bends in vent part of stack will be okay.

Inhibitor yes balancing no.

They do work but if you haven't done it before you probably would be better draining down.

You could buy a DIY freezing kit and freeze it rather than drain down.

Hard to say really, a few open ended spanners, average size adjustable, pump pliers, footprint, stillson etc.

Measure it and look in radiator manufacturers cat.

Not a good idea, better off to re-route it keeping it the same diameter.

Are you sure it hasn't got a small grub screw at rear just below swivel spout, hard to see you need to feel for it.

Okay your right ask for a Schedule 2, section 7,paragraph 16,G16.13/R16.13.1/2/3 kit :lol:

Your post is confusing me do you mean reduce the diameter of vent pipe or the length of it?. You can use a air admittance valve on internal vent DURGO VALVE.
