Flues in basement stairways

[buckley plumb]

What are the regs on this need to replace a boiler in this position. existing boiler is here but can't find much info on it

 

[lame plumber]

doesnt sound very sensible position for a flue

 

[hammers4spanner]

Anything you can do with a plumming kit?

 

[lame plumber]

fit a keston nice long flue runs

 

[Scott_D]

Is it flats or the basement of a house
If its flats it might be a fire escape and a no go

 

[GrahamM]

Need a bit more detail!
But generally as long as the plume will not cause a nuisance or encroach on neighbouring boundary there is no reason why cannot fit there.
As mentioned a lot of options with plume kits these days.

Found some info lightwell has to be 1200 wide and open both sides. Plume kit may do it got rep coming to look

Here it is, from current BS

BS 5440-1:2008
Flueing and ventilation for gas appliances of rated input not exceeding 70 kW net (1st, 2nd and 3rd family gases). Specification for installation of gas appliances to chimneys and for maintenance of chimneys

5 General
...

5.2.2 Location of chimney outlets in relation to basement
areas, light wells and retaining walls
Chimney outlets shall be sited so as not to discharge within the curtilage or confines of any enclosed basement area, light well or external space formed by a retaining wall or passage unless provision is made to ensurethe safe dispersal of flue gases as follows.

a) Chimney outlets from room-sealed appliances and fanned draught non-room-sealed appliances may be sited in such areas provided that they are sited not more than 1 m below the top level of the basement area, light well or retaining wall.

b) Chimney outlets from room-sealed appliances and fanned draught non-room-sealed appliances may be sited in a basement area or light well where this is formed by a single retaining wall that creates an uncovered passageway at least 1.5 m wide. This shall
only be done if the passage allows free air circulation beyond and around the ends of the structure and the retaining wall, if the passageway terminates at or above ground level and if
unobstructed air movement can take place at the open ends of the passageway.

Check MI though, hope it helps.

Cheers a bit confusing about floor level.

Cheers a bit confusing about floor level.

Have a read here, from a fire MI:

Basements, light wells and retaining walls - points to note
Do not site flue terminals within the confines of a basement area, light well or external space formed by a retaining wall, unless you take steps to ensure that the POC can disperse safely at all times. It may be possible to locate room-sealed appliances in such a location provided that they are not sited lower than one metre from the top level of that area to allow POC to disperse safely.

Light well - an area that may inhibit dispersal of POC
A light well can be best described to cover areas where for example, there are walls opposite and/or around the wall on which a flue terminal is located, that may be inhibiting the free dispersal of POC. An illustration of this might be the common Victorian urban terrace property, where the front door opens onto the street footpath across a narrow well, which provides light and possibly access to a cellar. It may also be the small central area in a square building designed to give light to the rooms on the inside of the building.
Be aware of the dangers of locating flue terminals where the POC cannot freely disperse. This could be accentuated by the possible accumulation of POC caused by several flue terminals all discharging into a single confined space.

I do believe your not allowed to use a plume kit to get the flue into a suitable position. its to get rid of nuisance plumeing only.

It is important to note that unless stated in the appliance manufacturer’s installation instructions,a plume management kit should not be used to circumvent the requirement to correctly locateany flue/chimney termination or air inlet position.

Correct to a point.
Plume kits can be used to give more flexibility on flue position. For example a Worcester flue can be put 150mm to a window opening as long as plume extension is at least 300mm away.

 

[newcastle phill]

Depends on the manufacturer if they state. But ordinarily cannot be used to circumvent the regs. Must comply without snorkel ordinarily and used for nuisance plume

Well Worcester, Baxi, Ideal, Vaillant to name a few, do allow you to circumvent the standard regs as far as general clearances go with Plume Kits. :yesnod:
They give a lot more flexability with regards to flue positions!

 

[newcastle phill]

Ideal dont. One of thier guys at wakefield told me flue position must comply with regs and only then snorkel can be used to avoid nuisance. He stated cant be used to correct an incorrect position.

What exactly are we referring to here?
Example...Fitting flues 150mm to window/door opening is permitted by Ideal if you use a plume kit.

 

[newcastle phill]

And can you point towards where it states that ?

Ideals MI's for plume kits for starters!

Can you cut and paste the specific info for basements instead of the complete MI

You are boring me now!!

 

[newcastle phill]

Sadly aint got time to waste on this but if you call ideal they will put you right re basements
