Smoking Stove

john_aero

Well i have had few issues with new stove fitted this Christmas. To explain ill start from beginning

Moved into house and fitted a small 8kw stove into the fireplace (using a 45 bend onto a angled pipe onto anto another 45 and into existing 8in flue. worked great and never really had issues with it.

Fitted a new boru 30kw stove and also lined chimney with 6in SS liner.

Fitted to stove using a 1m straight out off the back, into 2 45 bends into the chimney.

The stove works perfectly fine when running but when open it to re fule it pours smoke into room.

We added 1foot of SS pipe onto chimney and a china mans hat. this did not help the problem.

Have since fitted an anti downdraft cowl ( a pipe with 2 cuts on either side and large cover over the top)

This also made no difference to it.

The fire works perfect when closed. We do not have a vent in room but i have tried windo cracked open, 2 cracked open, fully open doors open etc but no change what so ever.

wen lighting you can see smoke/flames go up but can also see smoke rolling around against the door like as if there is too much volume smoke and noth enough space get out

had chimney lad in last week, he had look said chimney was fine and stove opening is too large for the exit pipe. now he did nto use a meter just lit bit paper and stuck in chimney. its liek draw is fine but cant get from chimney to stove.

I have cleaned it again and no difference but a lot of soot and ash came down only after 2 months of use.

we live beside i woods and i was out yesterday and had look whiel fire wa son. smoke goes out no issue at all and plenty off it, but it changes direction constantly even when thereis little or no wind.

I dont mine paying for an item to fix it just everyone saying try different cowls etc but would end up cost me fortune as they ar ento cheap.

When you lined the chimney did you use vermiculite around the liner?
One part I don't understand... 1 m out the back then into 45 bend? Is that pipe 1 metre on the horizontal?

Mean say .5m as just re measures it through stove cleanin hole. Yes horixontal .5m then up flue. As old chimney was damaged we couldnt fit a 45 straight and 45 again. Yrs flues was insated with bags of vermiculite. Just went and cleaned it after 3 weeks there is hige vume of ask in flue. Its about 5.5 lenghts of chimney rods long.

Regulation for horizontal distance off the back of the stove is max 150mm, any more than this will kill your draft and cause a smoking problem exactly the way you described above

You need to get this distance reduced somehow, it will probably involve removal of stove and fireplace to get right.

Installer should be called back to get this right as it is in the installation manual and building regs.

This is no difference than if the plumbing pipes leaked, plumbers problem and he should get it sorted

Is that 150mm from end of collar on stove? 500mm is from direct indide collor on inside of stove

Watching fire now. Flames are raging away and flowing up and arou d baffle fast like should. Smoke though is bellowing out chimney but still smoke rolling around inside

The 150mm is the max allowed horizontal length of flue.
Post pic and people will be able to advise better

I will get tape out and get exact sizes when fire is out in morning

Ok cleaned stove Z d after 1 month there was some serious amount of soot. Bery powdery and more like soft cotton wool

Ok horizontal pipe goes 300mm from centre of bend to inside if the stove wall on inside.

So put smaller fire on but let run lot hotter and burned better an less dirt on glass. So fire was at 1/2 air wash open on top an bottom auto damer at setting 6 with 8 being max. I used have it at 2-4 usually

Still post a photo
the flue length is still twice the permissible length

Herself had fire down by time got back. So sat down and opened the other door outside a bit. Opened the door into stove and wide open smoke didnt cone out it went up flue

Then 1 hr later (just now) with fire raging when crack door smoke came out so bizzare

The 300mm is non avoidable sadly as who ever built chimney before we moved in made arse of it. They forgot include height of floor on battond so wheb came fit fiteplace them smashed in bottom flue pot. So to get stove in we couldnt fit 2 45deg bends as per normal install as mean risking takin the plint holfing chimney up

How did you get on eventually.i have boru 30kw .this is my third winter and a replacement stove for last two .last yr and this yr was terrible .my house smells like a camp fire.the chimney has been cleaned .i cleaned all the inside of stove this morning waste of time.glass is destroyed .

I'd be interested (as I'm sure would a lot of people) to hear of possible solutions to this problem.

Boru Stoves: Richard

Hi motherofthree and JohnAero,

I am sorry to see you are experiencing issues with your Boru Stove. If you want to Private Message me your contact details I will ensure that someone from our service department contacts you directly about this issue and we will help you resolve it.

Kind regards,

not online in while,

but we have stopped using stove.

room still smells of soot and no one from boru or shop have even bothered call me back or visit house. all i get when ring is if we followed install guideleines and fitted 4 different types cowls then tough luck.

boru's attitude was "our stoves never give toruble so must be you thats the issue"

had chimney specalist otu and he has confirmed chimney is working perfectly

we even removed stove, checked everything and made sure stove goes into a 45 deg bend out the rear , straight then 45

there is now 2" horizontal lenght out rear max and that is inside the collar of the stove. we took a section of the concrete plen out to ensure fits in correctly and no horizontal sections

Ok a quick question do you have an adequately sized wall vent in the room ?

I am wondering is it possible that when the fire is roaring that the room is being put under negative pressure as the stove is drawing the air in, and if theres insufficient ventilation whenever you open the stove door, the air rushes down the chimney to balance the pressure.

The problem I describe might only occur when the fire is roaring it might not be noticeable at any other stage.

Could you possibly light a fire let it get going fully but open the window in the room wide a few mins before opening the stove door. If no smoke comes out then its possibly a ventilation issue.

And one thing all stove installers say is to open the stove door slowly at first to give the increased draft a second to clear the smoke fully from the stove before fully opening the door.

How high is your chimney should be a min of 5.5 mtrs from hearth to flue pot.
Also what fuel were you burning?As I said previously a few pics of the stove,the chimney, the connections between stove and flue would be very helpful.

john_aero

as saying all buried inside so cant get pics as all not visible when stove fitted. all get with a pic if front sove nothing else

chimney from memory was between 5.5 and 6mtr as we did measure it.

we even fitted a 2mtr extensio pipe to see if helped

we have tried all fuel,

i have supply of dry fuel,

so far, turf, timber, coal (in its various types) and mixture of all




with regards vents, we have tried all combinations, to see if need more vents, have window each side and door on opposite walls.

we tired all combinations of them open, cracked open, full open etc. to no avail

john_aero

efore stove went in, the pipe literay was cemented in at angle so all issues regarding too long a pipe comming out rear have been delt with

john_aero

i will see an get mirror and camera in to show under and behind stove
