Hi,

I've moved into a house and had a couple of jobs done (in this
order)...

1) Got cavity wall insulation fitted
2) Replaced the electric fire with a gas fire

Both jobs have been done by "professionals".

The gas fire uses a pre-cast flue which is connected to a raised roof
tile on the top of the house.

Recently, when the gas fire is on at over 50%, I've noticed the wall in
front of the metal flue is getting extremely hot. So much in fact, the
paint is starting to blister, and the walls are too hot to touch.

I'm a bit stuck at what to do next, other than not use the fire. Any
suggestions?

Thanks in advance.
