As fire bricks are exposed to intense heat and direct contact with burning fuel it is important to inspect them regularly for signs of wear and tear.
They will need replacing if damage to them begins to expose the stove's bodywork to flames.
There tends to be three types of stove fire bricks
1: Traditional refractory clay fire bricks
2: Heat reflecting vermiculite panels
3: Steel / cast iron fire panels.
You can extend the lifespan of cracked clay fire bricks by filling the cracks with Flue Seal High Temperature Fire Cement.
Replacing Fire Bricks
Clay bricks - When they are breaking into small fragments or crumbling.
Vermiculite panels - When they have a hollow or indentation.
Steel or cast iron panels - When holes appear in them
These Smartcare vermiculite fire bricks can be used to replace existing vermiculite fire bricks or clay bricks.
This is because the vermiculite panelling can be easily sawn and shaped with any type of wood cutting saw so that fire bricks for even the very oldest stoves can always be safely replaced.
The cast iron fire cheeks that some manufacturers use, particularly in traditional inset stoves, where space in the smaller fire chamber is at a premium, are generally thinner than vermiculite or clay firebricks and therefore should be replaced with like-for-like where possible.

2: Clean the baffle plate and flue.

4: Remove fire brick carefully using a chisel or screw driver if it is difficult to dislodge.
5: Insert new fire brick using Flue Seal Fire Cement as an adhesive and reassemble.
