Fitting limestone fire place and cast insert

[electrospark]

I'm fitting a new limestone mantle and cast insert and looking for advice on how to fit it. I'm not doing any gas work, this will be a gas safe plumber.

When installing the limestone surround should I take the plaster off and fit it directly to the bricks or can I fit direct on the plaster?

The cast insert... Is this simply put in place and held in by the fire surround or is this fixed in some way?

Any other tips would be great.

Thanks in advance....

You need to speak to an RGI BEFGORE doing any work. I assume you bought it off the net, rather tahn a proper shop. This is the problem with cheap deals, you don't get any service or advice which should be part of any purchase.
