Supporting chimney in bungalow

[BigClick]

I have a 1960 bungalow with a brick built chimney

There was never a real fire installed just a few bricks removed for a gas fire flu

I want to open it up for a burner.

There is no gather behind the opening but a second course of bricks in front of the rear wall. This second course holds up the chimney section bricks that are at right angles to it they are three bricks wide end on (350mm) each side of the chimney hole.

I would have to remove this second course of supporting bricks to 900mm high to get the depth I need for a burner, which means I have to think about supporting the chimney section between the front lintel and the rear wall.

My idea is to use a length of stainless steel flat bar 50mm X 12mm underneath each end on brick between the top of the front lintel and a between the rear wall. This gives a span of 250mm with a 100mm bearing on each end. Sectional drawing attached.

I do not think this needs calculating because to me it seems more than adequate.

I was hoping for some reassurance from forum members.

Have you got flue liners, and are you putting an S/S liner in?

Hi Stuart,

Yes I will be putting a stainless steal Liner in.

I will probably get a certified installer to do the commissioning so I can get a letter of conformity (or a certificate of some kind)

Building control are due to inspect the opening before I render /plaster (they are doing this during an inspection for other work so wont cost any money).

if you put up a photo or two of whats existing it would help.
whats the name and ref number of the proposed burner?
do you have a hearth?

Couple of pictures at this icloud folder... https://www.icloud.com/sharedalbum/#B15GgZLKuJ5FWX2

Was thinking of something like the Clearview Pioneer 400 with possibly a slate hearth but would welcome any ideas or advise

youd be better off if a HETAS came and had a look before you go any further.
and have a definite choice for the appliance.
have a read of the posts at the bottom of this page.

Are there any HETAS recommended by this forum near Walsall?

So a HETAS engineer called round for a very reasonable charge and said he would be happy to sign off my design.

I have gone ahead with it and it worked out well.
