I live in Northeast PA, and we have a lot of rock quarries and bluestone in this area. I have a couple pieces of very nice, very large rectangular cut bluestone. As long as they are the right size according to specs (distance from edge to front of stove, side of stove, etc) is blue stone a useable material for a hearth? I was going to build a pedestal out of brick or decorative stone, and set the big piece of bluestone on top. This is all going on top of linolium.

I had slabs of that for the old stove. When I had the house surveyed for the newer stove (twice) both said they were a no go cause of the cracks where they joined up. So I gave up and got a hearth pad.
savage - interesting...did you have the joints between slabs pointed or were they just open air gaps?
Seems like if you stick frame the hearth, brick (or brick tile) face it, cement fireboard or a hearth pad on top and set bluestone on top of that you'd be more than safe. Might want to beef up the lower floor's framing below the hearth and add a lolly column or two just to be sure you are fully overdoing it.
One of the hearths in my house is bluestone - elevated in front of a fireplace. I'm thinking about a second stove in this fireplace and that is how I planned to extend the existing hearth.

I've had a bluestone hearth for over 20 years and it passed inspection. It is mortared between the bluestone pieces. My stove has a heatshield underneath so the bluestone stays cool.
On another note I am really interested in your stove and eventually I want to get one. I need to devise a way of installing it so I can remove the pipe for cleaning without having to move the stove. At 475 lbs. I don't ever want to move it after placing it... Is this possible or am I asking too much? Is there some sort of slip pipe I could use? My current stovepipe arrangement goes up about 3' then to a 45 and then 90's into the chimney.. How is your stovepipe set up?

Meathead our blue stone slabs were not mortared...we just joined 'em up as close as we could together and I don't think you could get a credit card between 'em. We wanted a non permanent hearth so we can re-carpet as needed, the stove is by a high traffic area near a staircase. Wall to wall to so inexpensive today I rather re-carpet than dick with a wood floor that's why we settled for a hearth pad. Our blue stone was 2 1/2 thick and the 3 stones, if joined permanently would be to heavy for me.
raybonz you talking to me???
I have a QF4300st and regardless of stove you should be able to remove any pipe off a free standing stove for cleaning...without moving the stove. Just juggle a little from the bottom then the top and repeat until done. Then again were going into a thimble and that does make easier.

The trick is to put something underneath the stone that provides an impenetrable shield to embers. A sheet of metal might suffice if the hearth requirements are light. If not, some micore and/or a sheet of cement board might work. As further insurance some fine sand can be worked into the joints.
Thanks for the replies. I think you guys misunderstand me though, I am talking about one LARGE piece of bluestone, not many small pieces. So gaps are not an issue.

^well our bluestone was slightly less than half a city city sidewalk square...it took 3 for the pad.

Links to our latest blue stone heart in the sig below. We built two others in our previous home, all one piece. 6-8 feet wide, 24" deep, and 2-3" thick.
The only consideration I think you would have is if your stove needs r value insulation on the hearth, and the bluestone is sitting on combustionables ???

The bluestone is sitting on concrete blocks and the blocks are sitting on linolium. I left an airgap between the blocks for airflow.madison said:
