Fire Pit installation can be easier with our 31 inch heavy gauge galvanized installation collar, of an appropriate size, mortared in just below the top course of the enclosure. Makes pan and valve box easy to access. The ID and OD of the installation collars differ by 6 inches to allow a small space between the side of the pan and the collar and allow 1 inch or more of the collar to project into the body of the enclosure and mortared in if desired. The collar should be installed into the enclosure while it is being built and be at least 8 1/2 inches up from the bottom of the enclosure. They should be 4 inches to 8 inches below the top of the enclosure.
