Hello all, I know there are lots of posts about opening up fireplaces, but I would like to know if a: It is going to be fairly straightforwards to remove this parkray burner out, and b: if the fireplace integrity will be unaffected? I'd like to remove the brick surround and the hearth tiles to find out the actual size of the real opening. We would like to put a wood burner in there and wish to do as much of the work ourselves as poss to save a bit of money. Thanks in advance x
