Firebrick Size

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

The thinner ones are called "splits", both are available at almost any masonry supply. The spilts are about a buck apiece.

Hi chet, the thicker brick may overlap the edges of the grates preventing them from moving or moving with enough travel to be effective.

I'd replace the bricks with original size if you need to change any of the bricks.

You don't want the grates touching the brick at any time, especially when shaking. My boiler is always breaking the end bricks because of this. As a matter of fact, when the unit is cookin', stay away from the brick. It doesn't take much to break them when they are real hot.
