Smoke seeps/leaks out the joints off our log burners pipe connections, is there anything that can be used to seal the joints to prevent this?



Thanks

you can get a heat resistent cemenr/putty stuff, used it to seal out log burner in the UK, it will need a big enough gap to force some into.

Probably get it at most Yapis, but more definitely at the fireplace shop Akinlar (don't think it's spelt like that but something similar) half way between the Belleapais trafic lights and the main Ky-Nic roundabout, you are in Ozankoy so must know where I mean.

You need to get it sorted because it is not just smoke that is escaping it is also Carbon Monoxide.



Like yrret says you need Fire Cement.



The problem is it dries very brittle and crumbles in time with heat, also the pipes have bit of natural movement so it will drop out in time.



You should really check it every season.



The best thing to get if can find it , I have only seen it once used by a friend of ours who made his own stoves and it is heat proof silicone.

I have seem high temperature RTD silicon but I’m not sure if temperature of the pipe will exceed its working capacity.

also get your flue pipe swept,if you have a 90 degree bend going outside of the building the carbon builds up there,where hot air meets cold air.then reseal your joints with rtv silicone must yapi markets sale this.

I was in a cafe last week and they had the same problem. The owner was using what looked like 5ins wide sticky, silver paper which he had bought from a local Yapi Market and he was winding around all the joints. He said it was both cheap and very efficient.

Tango I no not safe I think sorry to appear rude but the locals do not have health and saftey in mind.



Carbon Monoxide will kill you and if it it does not kill you it will do you the most horrendous damage especially if it is taken in small doses over a period of time.



My wife and I (and our cat ) suffered it from an open fire in a property in Karmi that we rented.We caught it early due to the Cat showing worse symptoms, a bit like the canarys down the coalmine. The agent said the fireplace works perfect. They had not got a clue.



Also for everyone burning solid fuel or gas and I know people have said it before a good Carbon Monoxide detector is essential and of course a smoke alarm.

yes it is o.k.i have 2 log burners i use it on mine no problem.sweep my own every year and reseal the joints.it is red rtv silicone gasket maker hi temp. It is red in colour, so i use black heat resistant paint to cover it. If you need any help you can contact me on 0533 8765843

Thanks Cliff, I know the stuff your on about i'll give it a go!



JohnnyLee...Good advice for all I think regarding Carbon Monoxide detectors

Smoke comes out because there is a slight pressure in the flue. This is almost normal until the chimney is warm which then when the hot air rises it creates a slight negative pressure. I menton this as it slightly implies that the flue is not drawing properly, either not high enough, slightly restriced flue, too many bends etc. Also if the top of the chinmey is below the roof ridgeline there can be a slight down draft when there is a wind. Those spinning cowls do help prevent suddent 'blow backs' . Fire cements is good, but as others have mentioned it is brittle, aluminium tape will also work. If the gap can be cleaned out and repacked with either glassfibre ( it used to be asbestos!) and made good wih fire cement,

Also for smoke to go up the flue a similar volume of air must enter the building try opening a door or window, it certainly made a difference in one of our villas.

Good luck!

How is Carbon Monoxide (CO) poisoning caused?



CO is so dangerous because it binds very tightly to haemoglobin in the red blood cells and so reduces the amount of oxygen which can be carried in the bloodstream. Haemoglobin is the molecule in the blood that oxygen binds to in order to be carried around the body. The binding of CO to haemoglobin is actually more than 200 times stronger than for oxygen, so the CO effectively takes up all the space on the haemoglobin. In addition, CO interferes with the delivery of oxygen from haemoglobin into the body tissues.

These effects severely reduce the oxygen carrying capacity of the blood and limit the availability of oxygen to the body, with the brain and heart being particularly vulnerable. This can lead to anoxic brain injury. Pregnant women and the foetus are particularly susceptible to the toxic effects of CO.

Carbon Monoxide poisoning



There are approximately 400 admissions to hospital with Carbon Monoxide (CO) poisoning in England each year and around 40-50 deaths. CO exposure can lead to anoxic brain injury and this section explains what CO poisoning is, its symptoms, treatment and how to prevent it. A list of further useful resources is provided on the 'Useful links' page.

All the technical terms that are used are highlighted in bold and explained on the 'list of common brain injury terms' page, which you can access using the left-navigation.

The Carbon Monoxide information on this website is available to download in PDF format at the bottom of this page.

The man at Akinlar recommeded Carbon Monoxide detectors which he said , best to get from the UK............which we did.

a common cause of this joint leaking problem,eminates from the sockets on the pipe/bends/straight connectors are fitted upside down,the fitting/pipe should male into the female socket above it,I hope yours has been fitted correctly,if it has,there should not be any need to use flue cement,only at the flue spigot on the top/rear of the burner,check it out for safety.

mark&beck, Forgive me for stating the obvious but I recently had a similar problem whereas previously it had been working fine.



I had given the area where the pipes exit the sitting room a lick of paint and in doing so I had opened the pipe joints a tad. I didn't notice it for a couple of days but once spotted I pushed the joints back to a nice tight fit and all's well since.



Good point post 17.

Yeah I have double checked there all well connected, I think I'll try the RTV silicon or fire cement.

mark&beck just one more thing a couple of times in the UK my fitters ran out of firecement when fitting on site and they would nip to the local garage an buy Car exhaust Paste. (it gets harder with heat)



It did work.
