Multi Fuel Stoves(Fires)

littlelady

I need some advice please help!I had a freestanding open fire with a 8 inch flue which came out the top of the fire and went into the chimney breast wall.I have removed the open fire but have left part of the flue in the wall .I want to have a multifuel stove put in but want to connect to the existing flue left in which comes out the wall with a elbow fitting .My hearth measures 26 depth and 51 wide.The wall behind the fire is breeze blocks and the chimney has pot liners upwards.The size of my living room is 30 x 12 x 9 and i am thinking of a 10kw fire.My question how easy are they to fit and would we be able to do this ?The fire we are looking at is the country Klin 3,the fire measures 22.25inches height,26 width,18 depth,the flue size is 6/7 diameter and as my existing flue is 8inches how would we connect 8inch with 7 inch?.
I do have pictures of the fireplace and the flue in at the moment but i dont know how to attach them to this thread ?Can anyone advice me please?Thank you.

hello,

so the flue goes through a wall and into a chimney on the other side is that right?

either way your probably going to find that an 8 inch flue is too much for a closed appliance. 8" in minimum for an open fire.

8" on a stove would just work terribly. It would be easy enough to fit yourself as long as you followed the guidelines required as if you modify anything to do with the fire/flue it comes under the 2002 building regulations (document J) however you would need to get the installation signed off by a building control officer.

If you can post some pics and give me some more info on the chimney layout etc I can advise on what needs to be done.

To upload a picture do the following:

Stoveman, here are the pictures.

hello,

thanks for the pictures.

You need to work out if you can put the stove into position and still be able to get the flue to come up straight inline with the existing pipe there. Building regs state that you have a minimum of 2inch gap behind the stove. From doing my research the middle if the flue collar from the back of the stove is 5" so work out if the flue was to come up would it go inline with stove and still give you 2 inches behind the stove.

You also need to ensure that the hearth you have there will be 225mm in front of the stove when its in position and 150mm each side of stove.

My advice regarding connecting into the 8" pipe would be to run a 7" pipe up off the stove and run it up inside the 8" pipe and then pack the gaps in with Fireproof rope. By packing the rope in there as tight as possible will fill the gap and ensure no smoke can come back into the room.

My only concern is that you do not have any sweeping access on that existing pipe, has the chimney been swept recently if yes are they able to get a rod up the pipe ok?

I would advise getting the 7" pipe with a sweeping access panel on it so it can be swept at a later date. The chimney should be swept at least once a year.

hope this helps

The chimney was swept last week just before we took the open fire out,thanks for your reply ,i am confused though it all sounds very complicated do you think we could fit this flue and multi stove ourselves?do you think it would be better to take away the last of the attached flue and start afresh with a smaller one ?the company we are thinking of buying the stove from said all we should do is to buy a reducer 7 inch flue connection which would attach to the excisting 8inch flue?

hello,

if you can get a reducer then that would be better yes.

The problem i can see is that the pipe that comes out of the wall is basically touching the wall, meaning for you to connect a new pipe to it and run it straight down into the stove would mean the stove would be up against the wall.

Building regulations state you should have a minimum of 2" behind the stove (more if the stove manufacturer specifies more)

With regards to installing the stove your self, yes its easy, sit the stove in place push the increaser into the existing pipe and put the 7"pipe into the increaser and ensure its into the stove collar securely.

Technically if installing yourself you should get someone from building control to come in and sign the job off and provide a HETAS certificate.

hope this helps and feel free to ask any more questions
