Hi all,
Having just read Stephen's post about boiler flues I'm getting worried about the location of mine.
Very poor ASCII art follows, use non-proportional font:
________________ | | | | | | | | | | | | |_______|______| | | | | | | | | | | | | |_______|______| ^ | | | 1m | V FLUE -> 0___________ 250mm| | | | | | | | | | | | | | | | | |
The capital O is the end of the boiler flue. It comes straight out through the wall from its cupboard. It's almost exactly 1m below the bathroom window (which I think is OK?). However, it's 250mm from the top left corner of an external door, which I think might be a problem? In fact the door is virtually never opened, we use a different door to get to the garden, and the boiler has been there for several years with no ill effects.
In fact I've just found this in the installation manual of my boiler's successor (the Ariston microgenus HE, condensing model, which is what I'm likely to replace this one with):
TERMINAL POSITION mm A - Directly below an open window or other opening 300 B - Below gutters, solid pipes or drain pipes 75 C - Below eaves 200 D - From vertical drain pipes and soil pipes 75 E - From internal or external corners 300 F - Above ground on a public walkway or patio 2100 G - From a surface facing a terminal 2500 H - From a terminal facing a terminal 2500 I - Vertically from a terminal in the same wall 1500 J - Horizontally from a terminal in the same wall 300 K - Horizontally from an opening window 300
It doesn't actually mention any rule governing the horizontal position from a door. The closest is (K) - horizontal distance from a window. However, presumably windows are different from doors because they are inclined to be left open for long periods for ventilation, rather than just used for going in and out.
If the rule is 300mm from a door, I might just about get away with it if we're talking about the distance to the centre of the flue, rather then it's outer circumference.
Am I worrying about nothing? Will I get condemned by the gas man? Will we all be gassed in our beds by boiler fumes? Should I nail the door up and have done with it?
Cheers!
