the inner jacket and secondary heat exchanger chamber are also stainless steel. The stainless steel screws are identified by a sealing washer mounted on each screw. DO NOT mix stainless steel and standard plated fasteners when disassembling and reassembling the inner jacket sheet metal components. Standard plated fasteners may be damaged by the flue product condensate when used on the inner jacket assemblies.

Outer Jacket - The outer jacket assembly is constructed from steel, galvanized on both sides. The galvanized surface is specially prepared and phosphate coated to allow application of a multiple coat enamel paint process. This coating process ensures a long life from the jacket assembly.
