Please help : Need Advice on what to buy for moving Gas Flue

[wildfirejc]

I have a CDi24 Worcester Combi Boiler using Natural Gas. I am quite sure it is the CDi24 RSF model.

I am building a conservatory at the back of the house and the flue is in the way.
So my plumber has suggested he move the flue around to the side of the house...see picture.

He told me I needed a 135 deg bend, a terminal length of pipe (1 mtr) and one extension length (smallest abt 750mm).

So I checked it out on the internet and found the following: 77161910100, 77161910140 and the last one which is the terminal length got me confused and I was told by this internet sales guy I needed 77161910090 which is the standard flue kit. This last thing costs over £122. So I am qondering if I really need that. Can someone in the know advice me please?
Can't the plumber re-use the parts? He said he can try but if I don't buy them ready - and if he needs it - then it may mean a delay of getting everything sorted within an afternoon. Help!

If the terminal is in ok condition I'd reuse the one you have mate, as long as it come out without a fight too.

You need a proper gsr in to look at your boiler. We cannot and will not give advice on the installation or repair of boilers or chimneys for your own safety.
