Title: Oil Boiler Flue
Post by Bob on Dec 4^th, 2006, 1:52pm

I'm planning on a oil boiler in the distant future, the position of which amoung other things is determined by any regulations the flue has to comply with, ie does it have to be above windows, above the roofline, away from windows by a certian amount, travel only in a vertical direction (ie through the roof, not out through a wall first) etc. Anything like this would be of use as I don't want to bolt a big cabinet to the wall then have to move it again.
Cheers

Yes to all your questions plus lots more.

Your oftec registered engineer will be best to advise after a site visit.

There is some stuff in the Building Regs that covers the position of flues (Part J if I remember correctly) but I don't think this is all you need to comply with. Take thescruffs advice to have your installer call.

Generally: It can go straight out through a wall (eg It doesn't have to go through the roof) but there are restrictions on how close it can be to openings. It can be below the level of windows as long as it and they meets other restrictions.

Don't forget that the make and model of boiler may impose it's own restrictions.

Our boiler (a recently installed Grant) is floor mounted against an outside wall. The flue goes straight through the wall horizontally at a height of about 3 foot and terminates right there. It's all of about a foot long.
