Hi, we're currently trying to open up our fire place to fit a log burner, we have picked it back to the blocks. The chimney has a pot lining which is very low, with also a very low lintel. We understand that a lintel will have to be installed higher up but how do we open this up without the the lining falling? I have attached photos to try and help. Thanks

Hi. Thanks for the reply. Yes we understand the regs etc, and are looking at getting the Nero 5kw burner as its not a very large room. The only thing we're not sure of is how to support the lining and break away the section of lining we don't want while opening it up?
Then go to the height installation dimension and allowing for a lintel go 2 or 3 courses above the install height.
Then open up to insert an Acrow Strong Boy centred over the opening.
Assuming the flue lining stays in place then remove the lower bricks and slice the flue liner with an angle grinder.
(you could prop the liner with a few lengths of say 2 x 2 or 4 x 2)
then install the lintel.
Where exactly you slice the liner will depend on where and how you connect from your appliance to the pot flue liner.
Its typical to drop a flex SS liner down the flue?
A Register Plate will often have to be used.

Sorry for long delay in reply! Still not carried on with any work, been in contact with local builders to do it but the one's who have got back seem to have extremely high prices! (around £1000 to open) So looking at doing it ourselves again! Would the clay liner need to be supported with steel rods before inserting a new lintel and removing blocks? Or should it be self-supporting?
Personally I would consider an inset wood burner in there as I think one would fit without too much further work. Stovax Riva are good as is is the clearview but its expensive

Thank you for your responses. We have now opened it up for the log burner and are ready to plaster. We are getting a HETAS installer to fit the log burner but we are doing the plastering/decorating ourselves. We are going to hardiebacker around the log burner, but my question is who installs the closure plate? Us or the hetas installer? There is no liner down the chimney yet, so if we install the closure plate using a hardiebacker board how will we know where the hole should be for the liner? I am assuming it would be difficult to fit the closure board after it has all been plastered though?
whats on the quote from installer but it should be part of the installation they are certifying.
What is hardibacker being fixed to, if battons I'm not sure if thats classed as non combustable if distance is nearer than specs for stove and flue but you'd need to check

Yes, we're not sure how to secure it if its us fitting it. I have read that it sits on top of the sides and back board as a shelf and secures to the lintel, but if this is the case we would need to cut the hole into it first, which we don't know where to put? But if we leave it to the hetas installer, i'm not sure how he'll get it in and secure it once all the other plaster work has been done?
When I say battons I refer to your cosmetic area not the register plate which is normally fixed to angle irons up above the stove
