Builders opening for multi fuel burner

[Craigbillo]

Hi all,

 

I'm currently opening up my fireplace for a burner to be fitted. I think I have found the lintel. Any advice on if I can now remove everything below the lintel? Thanks!

The lintel will still require at least 3 inches of brickwork to rest on and you can only remove those two rows of bricks below it, that lintel looks like wood from the picture, is it? If so you should replace it with concrete or steel. If that is the case make the opening as large as you want by moving the lintel upwards.

Well you obviously have to leave the ends of the lintel supported so not "everything". Bearing ends are normally 100-150mm long.

Seems pretty straightforward to me - already has a decent bearing. Just take out the two courses below and make good.

If the lintel is wood I would have thought you could clad the underside  with some hardibacker or something like that. I used hardibacker as the register plate for my burner.

But it looks like concrete lintel to me.

Thanks all,appreciate the advice! Lintel is concrete, I've now removed the two rows of brick below and will take it from there.
