I have 4 of these 18'x28'ish brick panels that came out of a natural gas pool water heater. They seem a lot like fire brick material to me, they seemed to have served the same purpose as our firebrick. So I'm trying to find a use for em. Any reason not to set them on the back and sides and top of my insert? Hold a little more heat in maybe? I don't know just a crazy thought.
 
If I follow what you are thinking, I don't think I'd set stuff like that on the stove. The firebrick inside a stove also act to protect the metal. On the outside, you are going to insulate the stove and you won't have it radiate into your room. Doing this could leave you cold and run the risk of overheating the stove since the heat can't get out.

I hear ya. Just was thinking since its an insert that might keep the heat in where it can be pushed out into the room instead of off in to the masonry. Sure dont want to overheat though. Thanks for the input. Another question on similar lines, I'm replacing ceramic wool insulation on baffle. I have a two piece baffle approx 6x24 each with insulation on just the back baffle. Think there is a functional reason they only put it on the back baffle? The piece im buying is 12x24, thinking about just laying it over both baffle pieces..
 
late to the party...the material in your heater is not a "fire brick" its a vermiculite based material. it will not hold heat, its function is to direct heat toward the heat exchanger at the top of pool heater.
for some crazy reasons rodents find it delicious and good bedding material.
