I had a quick question does anyone know the minimum distance an osburn 2400 has to come out from the fireplace opening. Like how many inches from flush of the fireplace. Thanks guys.
 
According to the online manual, the 2400 can protrude in a range from 7" to 3 1/4". At the maximum depth, you will need a fireplace depth of 20", and the air jacket will be back from the faceplate facing 3 3/4".
 
Remember to compensate for that space in depth into your existing fireplace. I have the Osburn 2400i set to protrude into the room the max. I like it at this setting because it pours more heat into the room, and if we lose power it is helpful to have more mass in the room if we can't use the fan. I also do not have a choice as my fireplace depth does not allow for any other settings. Hope that's helpful. Good luck!
 
I measured my hearth and if I have the osburn sticking out the minimum at a little over 3 " I have 13" of brick out in front. According to the manual it says I need 20" in front of the door. Everytime I see pics of the 2400 it never seems like people have that much hearth in front. is 13" enough hearth to safely operate?
 
You don't want to short change this, especially if the hearth is at floor level. The 2400 is going to radiate a lot of heat from the front door. And embers can easily pop out of the stove for a foot or even two. Is the hearth elevated substantially or flush with the floor?
 
Its elevated at least 6 inches probably closer to 8
 
That helps. I would still have ember protection at floor level out to the recommended 20". This can be done with an extension hearth pad a permanent tile or stone boarder, or in the least a fiberglass hearth rug.
 
So an extension pad just sitting on my hardwood floors in front of the unit would suffice? If thats so I still would like that insert. I just dont want to have to build a bigger hearth.
 
Yes, that would work. They make hearth extension pads just for this purpose.
 
My insert called for 18" in front of the glass. I went out to about 21" and glad I did. You get some serious sparks that can fly out of it plus some serious heat.
 
Aghhhhh I dont know what to do. If I have to extend my hearth 7 inches just to meet my minimum requirement due to my fireplace being over 6 sqft it is really going to eat into the room. Not to mention I doubt my wife will be up for that, but at the same time she will want to be as safe as possible. I just dont know how to make it look good since its raised 6-8 inches and brick. Either having to build another 7 inches out and 6-8 inches high of brick is a lot of hearth. Tiling out in front would look out of place with all the hardwood floors on that level.
 
Tiling can look great. It could be with terra cotta tiles to pick up on the brick color or perhaps tile with 12 x 12 slate tiles.
