I currently have a standard "hole" where my fire used to be. I have purchased a stone "hole in wall" type of fire surround and need to arrange for it to be fitted, but first I need to know exactly how it should be done to ensure that whoever fits it does it correctly. I can't seem to find any information anywhere. Can anyone help? I need to know the height at which it should be set, what kind of brickwork will be required, etc.
Grateful for any help. Thanks.
