Firebrick Rating and Availability – December 2020

Each GARN® WHS unit has a combination of #1 and #2 brick splits. #1 splits are the thinner 4.5” x 9”x 1.25” brick that stand on edge along the sides of the combustion chamber. The #2 splits are the thicker 4.5”x 9”x 2” brick that lie transversely on the bottom of the combustion chamber. Because of the high temperatures experienced in the combustion chamber only Hi-duty firebrick (rated to 2,700 F or higher) are recommended. All brick sold in the GARN store have been upgraded by our supplier to a maximum service temperature of 2,850 F. Standard “fireplace” brick does not have the Hi-duty rating, thus will not survive in GARN WHS equipment. Click here to read more.
