De Dietrich Complete right-hand side section 83585510

This is a complete right-hand side section for a De Dietrich heat exchanger, SKU 83585510, also referenced as 336.709.008. It is designed for use in De Dietrich DTG 320 ECONOX boilers. The section forms the closure at the right-hand end of the assembled heat exchanger block, containing water passages and flue ways for heat transfer. It is a replacement part for the right-hand side position in sectional boiler heat exchangers.

Parts of this type are selected by boiler model and position (right-hand side, left-hand side, or intermediate). The replacement section must match the original in overall dimensions, port alignment, connection threads or flanges, and the number of flue passes. Ensure the section is the correct orientation for the installation, as right-hand side sections are not interchangeable with left-hand side or intermediate sections. Gaskets sealing the inter-section joints are specific to the section design and must be compatible.

Failure of such sections can result from scaling on the water side, reducing efficiency, or soot deposits on the gas side, restricting flow. In condensing boilers, condensate corrosion may affect the lower regions of the section. Symptoms include reduced heating performance, uneven temperature distribution, or visible leaks at the section joints. Check for signs of corrosion, scaling, or soot buildup when inspecting the heat exchanger.
