Hi, I've just decided to install an insert into my existing fireplace. I think I have a pretty good idea of what I need to do, but I'm hoping the kind people here could provide any additional information or correct me if I'm wrong.
Here's a photo of my existing fireplace:

From the reading I've done so far, it looks like I need to provide 18" of vertical clearance from the mantel (the mantel extends 7" from the face of the brick). I assume this is measured from the top of the insert where it protrudes from the existing fireplace. Since I have 40" from the hearth bricks, that leaves me with an insert with a height no greater than 22". correct so far??
Also, I've read that the hearth should extend 18" from the face of the insert. I only have 13" from the existing fireplace, but as you can see from the picture, my hearth bricks are raised 11" above floor level. Do I need to extend the hearth an additional 5" at floor level thereby creating a two tiered hearth? Any ideas on this would be appreciated.
That's about all I have figured out so far. I think my height restraint in regards to the mantel will be the deciding factor in how big a unit I can fit into the existing fireplace. Additionally, I'm anticipating relining the existing chimney with double walled pipe and safing the existing chimney off at the existing damper.
Any thoughts on what I'm doing right/wrong would be most helpful.
Thanks in advance,
Mike
