De Dietrich 97956282 flame tube G40-3S/SR

This De Dietrich 97956282 flame tube G40-3S/SR is a component designed for use in the combustion head assembly of a burner. It belongs to the category of blast tubes and combustion heads. Parts of this type form the firing side of the appliance, where the blast tube length and head geometry directly influence how the flame develops inside the combustion chamber. The flame tube guides and shapes the air-fuel mixture as it leaves the burner, affecting flame stability and heat distribution. When selecting a flame tube for replacement, the critical parameters are the output range of the burner, the fuel type (gas or oil), the depth of the combustion chamber, and the flange pattern that mates the tube to the burner head. The exact dimensions and shape of the flame tube must match the burner design to ensure proper flame formation and safe operation. Always verify these physical details against the original part before installation. This specific article is identified by catalogue article 336.832.006 and manufacturer codes 97955683 and 336.832.006. It is listed under the De Dietrich brand. No further technical data—such as length, diameter, or material—is provided in the source information, so the heating engineer should rely on the part number and manufacturer codes to confirm compatibility with the burner in question. When replacing a flame tube, also inspect the combustion head gasket and any sealing surfaces to avoid air leaks that could impair combustion.
