I think I have to replace 8 cracked fire-bricks in a Fisher stove. Someone told me there is a pattern to follow, but, they didn't know what it was. Any idea how I might find this info? I have searched the forums and a couple of other places. Not particularly good at jigsaw puzzles.

I'm getting ready to mass- replace all 21 firebricks in my stove. A lot of mine on the sides are cracked, and parts are missing. The only pattern I can see in my stove is that, once you get the old bricks out, the new ones go in sides first, then the 'floor' bricks. Looks like you do the back end ones, then either side working forward. The 'floor' bricks would go in last. BTW your stove looks very similar to mine- the clips above that hold the side bricks. And it looks like yours is also floor bricks last. I think you may have to completely remove all bricks, even though you intend to only replace certain ones. The bottom parts of the side bricks are covered by the floor bricks. I suggest removing any bricks you can, in any order you can, until they are all out. I'm going to make a sketch showing the brick placement in mine so I don't forget my stove's pattern.

BTW you can save some ash and then later work the ash down into any cracks between the floor bricks you place. If you don't have any ash right now, I think you can just not worry about it. Soon enough some new ash will work its way down into those cracks.

In my stove, some partial bricks are used. I'll have to saw- or score and break- to get those smaller pieces.
 
All the bricks I've seen on our non EPA stoves just stand up and align side to side with one another...hope that's of some help to you.
 
Should I be replacing cracked pieces of firebrick when I see them immediately, or is it OK to simply replace them as you guys seem to be doing at one time in the long future. I have one cracked firebrick on the floor of my Quad, it's not missing pieces or chipped, it's just cracked.

Good luck trying to remove the bricks to get bad ones out. I had to break practically every firebrick in the old smoke dragon that I removed this year to get them out. (It still weighed a ton with the brick out and the door off.) I had thought that breaking 1 or 2 would allow me to be able to slide the rest out. Didn't work. I think I only got about 4 bricks from the bottom out without breaking them.
