Concrete Creations recommends that the fire bowl sits level. In earthquake or other natural disaster prone areas, it is best to anchor the bowl, and a concrete pad is recommended. There are two additional 3/4" holes in the base of the bowl for the purpose of anchoring. From the holes within the bowl, the pad should be carefully drilled, rebar placed and cemented down. If the fire bowl is on DG, you will need to have the shut-off valve on the outside wall of the bowl.
