Worcester Flue Clearances

[villa_tom]

Hi all,

I was literally just sorting out my paperwork for the accountant and found this print out from Worcester from when I did the course.

I thought I had lost it, I have always found it very useful. Then I saw Gaspastemanias post in the Central Heating forum so I thought I'd scan this and post it for you guys.

Hope it helps.

Tom

Quite a handy drawing that .
I asked the question on central heating forum as a friend of mine is quite inexperienced and has installed a flue thats about 100 mm clearance from internal corner at point of plummage . Few other issues there as well butr thats different story .

I just realised I've posted the picture of the plume distances. I do have the one for actual flue terminal clearances (which is what I thought I posted.) as soon as I find it I'll post it up.

I've got quite a few things like this from the Worcester course

Hi Tom, thanks for this info. I just did my re-sits in Feb and was told by the lecturers there that you cannot use a plume kit to overcome clearence issues yet this drawing showes that you can! eg.Flue leaves the building within 300mm of an openable window so a plume kit extension is used to gain the required clearence. Cheers!!

I've got an email from one of the top chops in GSR stating the same thing about using plume kits to overcome clearances. It was dated before WB published those drawings showing plume kits (though I believe MIs have said for a while that you could reduce air intake to 150mm provided exhaust stayed at 300mm, for example).

I can see both sides of the coin, truth be told; however, MIs take precedence and I'm happy to roll with what WB says.
