Chimney Flue

SerenaC

Hi,

I am thinking of inserting an inset multi-fuel stove. I have a gas fire (piped gas). The chimney breast wall is not solid and does not does not extend up through the bedroom above the sitting room. I have drilled a small hole in the wall above the fire place and its 10.5" before I hit something solid. The wall depth is 13". I'm guessing the flue goes up between the dividing wall,( I live in a semi-d, my sitting room and neighbours sitting room are back to back). Therefore i'm wondering if my chimney is suitable for a stove? There is a chimney stack on the roof and appears to be a standard size flue that used.

Any advise?

You will need to line your chimney with a twin walled stainless flexi flue liner in order to install and operate a multi fuel stove.

The flexi flue diamater will need to be the same size as the opening on the top or back of the multi fuel stove.

So if the stove has a spigot outlet opening of 5 inches,then you use a 5 inch liner

If its 6 inches,then you use a 6 inch liner.

Hi Paddy,

The stove i'm thinking if getting is the one you screw in and no need to break out the fireback. I have been told I dont need a flue liner with this type of stove but with the chimney I have would you suggest i still use the flue liner?

What do you mean by "screw in"???


Multi fuel stoves will burn at a higher temp than gas or a normal open fire,so you will need a stainless flexi liner in your existing chimney.

1-to aid and help the multi fuel stove to operate and burn propperly.
2-to prevent your existing chimney from being damaged over time.

the flexi flue liner should also be twin walled and stainless steel.

I have a Stovax Riva 66 multi fuel stove in my house,and the existing chimney is lined with a flexi liner and insulated too.

I want to be comfy and safe than sorry.;)

It is certainly not true that a chimney designed for an open fire is safe to use with a closed fire if the lining (material, diameter) is not adjusted to the new lay-out.

Was this a sales man who told you this?

Thanks Paddy,

I want to be safe and comfy as well. The screw in inset stove is a smaller version of stove that there is no need to remove the brick fireback. You just screw it into the fire back. The one I'm thinking of getting is the Boru Croi Beag.

Thanks

Yes it was a salesman that told me I didn't need to flue line the chimney with this type of stove. I was told that the natural draw of the chimney would be enough. That's why I was a bit confused. If I get an inset stove that I have to remove the brick fireback I was told that I would need a flue liner but not for the Boru Croi Beag.
