gas fire, open fire, chimney problem

[Mjolinor]

Need some input from a gas type worker person.

In my living room I have a gas fire (Flavel Emberflo I think IIRC)

There is no flu liner but instead of a chimney pot I have a small cowl. The house already had this when I got it and a Corgi type person commissioned it when I removed the old fire and fitted this one. The house was built in 1874 so it's just a stone chimney, very long, 11' 6" ceilings , cellar to roof is 3 floors + loft.

In the cellar I have an old range that I was thinking of starting to use in order to burn crap, wood and whatever combustible material I could lay my hands on.

Problem is that cellar and living room share the chimney and I wonder if this will be a problem. If I line the chimney for the gas fire then the outside of that will perhaps get really hot depending on what I burn in the cellar, if I don't line it then the gas exhaust will mix with the cellar exhaust and there will be a massive difference in temperature. Do I leave the gas cowl on or replace it with a normal pot? I don't know what effect any of this may have on the functionality of the system.

I wouldn't like to damage the wife as I can't cook and would starve.

The fire codes in most states prohibit venting two appliances into a single flue. Beyond the code issue, if you were to connect a wood stove to the chimney below the fireplace, it's very likely most of the smoke and gasses from the wood stove would end up in your living room via the fireplace/insert opening.

are you sure they share the same one as ive two fires in seperate rooms back to back and they share the same chimney brickwork but have separate flues
or else ya could do this

Er..... I would deffo get a HETAS engineer around to have a look.

The flue can go through the room, and as stated above it will more than likely be in the same chimney stack but have a separate flue. Even if the flue is knackered and leaking (guessing with your house being old it will leak) you can use a flue liner which will go down the chimney and be a continuos flue from the appliance to the chimney. THen on top you do need a special cowl - things that burn wood caol etc get a lot hotter than gas fires.

When dealing with stuff that can very easily kill you, it is not worth messing around - HETAS engineer....

They share a chimney and stack but do not share the flu. Both cellar and front room are separate until the bedroom floor then they join.

I proved this with smoke matches much to the disgust of er indoors when I decided which was the cellar, tied a bag over it, went onto the loft and removed a brick from the feathers and shoved the 50 years of crap down there.

4 year old son came out of the front room looking like a panda crying his head off and you could not see diddly anywhere in the house.

She still goes on about it and that was 15 years ago, memory like elephants have bloody women.

You mean the chimney, before I cover second born in soot or sweep the wife?

That is what I was doing when alleged accident happened (the chimney).

The 4 year old should be just the right age to sweep chimney ;-)

I'm not a gas engineer, but I think you have to be very careful of venting a gas fire and a open combustible fire below into the same chimney, flue or no flue.
If there was any unburn gas drawn into the flue....there might not be a house around it any more me think, So I stand to be corrected its a probable NO
A chimney from a wood or coal fire vents something like 1/5th the heat into the chimney to draw correctly so the flue for the gas fire could get hot even maybe distort from the heat sounds risky hopefully an expert will reply to your post.
Simple rule is unburnt gas sinks denser than air, burnt gas fumes lighter than air
IMO a fault in the flue and or gas fire there's a big risk of the gas descending down the flue-BANG

But the gas would sink anyway, fire in the cellar or not and there are no smells in the cellar so I assume it isn't sending gas into the chimney and its regularly cleaned anyway so if it does that I'll get a new house from the gas man.

I can't believe no one else has met this problem with shared chimneys.

They can share the same stack, but in my experience will have a different flue (tube) within the stack.

how many any pots do you have on your roof?

Thought this thread was about chimeyleg not flower pots

[Kalipo]

I think there will more than likely be multipul flu's sharing the stack..

When i was a child we lived in a very old house.. every room including the cellar had an open chimney with a pit in each.. if you are in the lounge and have access to the halve and it has a pit/well you shouldnt be able to see down into the cellar..

If you dont have a pit but the smoke bombs allow smoke to rise from the cellar out of the flu on the stack without leaking into the room above then your fine.. but with a house so old i would line it as the mortar could allow gasses etc to flow into any room above..

bit hard if each fire has a 6" flu

Think word of the day is hearth Also there is companys who do liners down chineys if you could break dk rules with liner companys and post details please, would love open fire thankssssssss
