Blimey, I think it most certainly should, however even if they are,
sometimes setting out due to the different loading can still give rise to
cracks at some time in the future.

Hi

I've just had an slimline blanced flue inset gas fire installed (Stdio 2
from
https://www.stovax.com/stove-fire/st...ine-gas-fires/ )

It required a new hole around 90cm * 45cm to be fitted into (no chimney
involved) - the work was surveyed by the fire company and performed by a
Gas Safe registered installer and the fire works just fine.

A small vertical hairline crack has appeared in the existing wall which
runs all the way to the ceiling - I'm pretty sure no lintel was installed
but I wasn't around when it was installed.

Should it have been? The interior wall is standard breeze block so there
would only be a couple of entire blocks hovering above the space.

The fire won't be load bearing but the above wall goes all the way the the
apex of the house, so a good 6-7m?

So - should a lintel have been inserted as part of the job?
