MultiFuel Stove Airflow Downdraft Problem

Crimson125

Hi All,

We had a stove installed where we live and have been having problems all winter with it.

We have 2 different stoves, a 6kW one, and this 10kW.

We use the same fuel in both of them - coal and wood - and have had smoke billowing out of the new stove ever since it's installation.

I've put a video together showing the stove, where it's installed and what's been going on with it.

Would appreciate some insight that anyone could give on what could be causing this smoke.

Stop using this stove immediately.
It's fitted so wrong it's not funny.
Max length of horizontal pipe is 150mm yours looks more like 1mtr
The tee is on the wrong way to act as soot collection.
The tee looks as if it's connected to asbestos pipe which is cracked then connected to galv flue which will disintegrate in no time.

Get someone to have a look at it and see if it can be sorted.
As I said do not use its dangerous

Hi Robbie,

As far as I know, the flue has been in place for 30 years by now but ive no idea when that concrete section started falling apart. Its been that way for 3 years or more anyway.

Whats the real danger here ? We've been using it all winter since it was installed...

There are two real dangers here the first one is fire the flue is running to close to timber.
The second and most serious is carbon monoxide your situationist just perfect for it bad draw due to improper flues badly sealed joints in flues and damaged flues.

Wow - ok. We did get a co2 alarm which fortunately hasnt triggered - the smoke alarm has often though.

Sounds like we need to get a technician out so. Thanks for the advice !

Any main specifics you see there ? We are renting and landlord has insisted it has worked fine for 30 years and this stove has been a bit of a bone of conention since then. Discussions have not resolved it for us so far and we are currently trying to get an idea of what exactly the problem/problems are so we can talk to her and get it resolved before next winter arrives.

Crimson,do not light that stove again!
It is extremely dangerous.Whoever fitted it should be named and shamed for putting peoples lives at risk with a job like that.
Smoke cannot travel that far along a horizontal plane,plus the timber cupboard as already stated is combustible etc etc.
Get a professional in and they will point out to your landlord that it is a hazard that could end up killing someone.
If they still refuse inform your local council or even the private residential tenancies board.

Who ever fitted the stove should be shot.
That's no joke.
The stove is not fitted to building regs
The hearth doesn't look as if it complies it should be a min of 225mm in front of stove.
The max allowable horizontal section of pipe is 150mm that looks to be around 800-900mm.
The tee is the wrong way around the flue can't be cleaned from the ground.
There is no debris collection point.
The flue joint at the tee is broken and would be leaking products of combustion.
The flue running up vertical is to close to the boxing around (distances to combustibles)
The flue looks to running up to first floor or through to roof there should be a fire stop on it.
If it's a single story building the flue would be running in single skin to outside which shouldn't be done.

I would be curious to see the flue higher is it a single or two storey building
Where does the flue come out of roof.
All those things listed are breaches of the Irish building regs part j.
Hope this is of some help

Hi Robbie,

The old original stove was fitted when the building was renovated from a barn to living space back in the late 70's I believe.

The original stove that was there up until last November had a huge crack in it which had been repaired with some sort of sealant, but it leaked smoke regardless as the crack was was quite significent.

We've been living here almost 3 years, but we hadn't used that stove due to it being very smoky - though we understood this was due to the stove itself and not the flue system (we're not stove specialists).

The new stove was installed last November by the landlords builder - and even though the horizontal pipe was full of soot and debris, it wasn't cleaned and the stove was installed and ready for use (we found this out a few days later when we opened it up and saw the buildup).

The full flue was cleaned by the landlord about 2-3 months ago, and it had to be cleaned from up on the roof downwards as there is indeed no way to get the poles up into the flue from the bottom side.

From what I understand here, apart from the "cement" section, the horizontal section going through the wall is a significent issue with the drafting.

By my measurements, it's approx 80-90cm long before the upsection of the flue on the join. I'm not sure what options would be available here to fix that given the position of the wall and the stove in relation to it.

I'll get some pics of the rest of the flue today and upload them. It's a 2 story building.

Starting to get quite worried now - while we have been paying a lot of attention to the stove, and have the co2 and smoke alarm, the comments from you and the other guys here who know what's what are quite concerning......

Sorry about any neck strain from the sideways pictures !


So this is the 1st floor. The Flue comes through the floor, and goes into the roof cavity. I'm not 100% sure what's in there, though I would suspect that there is wooden beams, and insulation. Not 100% sure though. THat section is about 5.5feet from floor to roof.




This is downstairs, and that is the upstairs floor that the flue is going through there. There had been water going through the old stove, but that has been disconnected for the new one - thus the pipes on the left.



The outside is the pipe on the left. The other one on the right is our second stove flue.



This is a closer look - it's quite dark up there for the camera at the moment !

It's what I thought the whole flue needs to be replaced the flue should be twin wall running through house.there are no firestops in place the flue is to close to timber,you should be able to touch the flue as someone could get burnt.
IMO the whole lot should be scrapped it's not salvageable.
It's dangerous on so many points
Fire hazard
Carbon monoxide hazard
If I lived in that house I wouldn't light that stove
