Purpose: The firebricks are designed to protect the fireplace from warping. They also keep the heat in the fire to ensure a cleaner burn.
Installation tips: Make sure that you clean all the ashes out of the firebox. Use a vacuum (a shop vac with a drywall filter is best) to clean all the ashes out.
Other Notes: Do not use a household vacuum and make certain that there are no embers in the ashes before vacuuming. If you vacuum embers, you will risk having a fire in your vacuum. Highlighted in yellow in product image.
