hearth extension

[BucksCoBernie]

Im looking to redo my hearth since I recently acquired an I3100 insert. Ive been looking around online for ideas and I really like the bluestone slab look. My question is if i pick up a 1.5 inch thick piece of bluestone that is long enough and wide enough can I just lay that down in front of the fireplace opening and be done with it? do you think that would meet code?

Do you know the R-Value or k of bluestone? I don't feel like searching online for it right now. If it cannot be determined then just lay some micore under it before you lay it down. I can't even remember what that unit specs for hearth protection. It might be the good old "3/8 in asbestos millboard or equivalent" which I did figure out the R for and posted on here a long time ago.

Is this going under the stove or just for spark/ember protection in front of the existing hearth/fireplace?

Its going in front of the stove for spark and ember protection. I need to extend the hearth about 12 inches out from the end of the area i broke up to be over the 18 inches for code.

The front is not just for spark/ember protection, it is also to protect from thermal radiation. This is taken right from the Quad 3100i manual. Not sure if thats what this person is looking at, I think another brand makes an i3100 (Hampton maybe?).

Thermal protection must be ('k" value = 0.84) or equivalent material*
Floor height 0" to 8" below Insert - 1 Inch (12.7mm) of "k" = 0.84
Floor height greater than 8" - 1/2 inch (25mm) of "k" = 0.84

I3100l is a Regency Insert...

Here's the HI300 Insert from Hampton (Regancy). I used a 1.5" slab of brownstone layed directly over wood floor. Mine passed because I have the stove on a raised hearth. I think your hearth is flush to the wood floor so that may be an issue with laying a slab on top of the wood floor.

Yep, i dont think laying a slab will pass based on what ive been reading. Im just going to lay down some micore and build up from there to get over the required 1.1 R value that Regency calls for in their specs.

Nice Hampton you have there btw.
