Part Description: RSF Onyx Refractory Bottom Plug

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.
