How to remove moisture from firebrick

I have a Pioneer Princess wood burning cook stove. One firebrick, next to the oven, is fairly large - approximately the width of three standard firebrick. The original lasted two years and the replacement lasted about the same amount of time. When it cracks it gradually allows ash to fall behind it and eventually the brick will begin to bulge making me think it could fall apart. This week I drove 2 1/2 hours to the manufacturer and bought a complete set of firebrick. I've read where it's a good idea to dry firebrick in an oven on low heat to remove all moisture. What are other opinions relative to removing moisture? The fellow at the shop thought it would be a good idea as they are stored in an area of the factory that's kinda damp. Our electric range has 170 degrees as its lowest setting.

John B. : I think it is possible to over think this one. Yes I would try hard to keep the temperature your new bricks were exposed to to below 212ºƒ or 100 ºç

I expect that placing them in your stoves oven with the door propped open will do the trick - How long to do this depends on your personal circumstances

And local Humidity NOW ! Good Luck ! For the Crafts Big AL
