These
vermiculite fire bricks line the fire chamber and protect the steel body from the heat produced by the fire. They can withstand extraordinary temperatures but will eventually need replacing.
Replace the vermiculite fire bricks if a crack has appeared which causes the brick to fall down or if you can see the steel body of the
stove through the crack.
It is advisable not to light your stove if the steel is visible. If your throat plate brick has fallen down don’t use your stove as it will distort the throat plate. We supply fire bricks for all models of stoves and can cut bricks to size.
