90° chimney elbow with inspection opening SOLINOX Ø150 (inox 304)

The SOLINOX 90° Ø150 chimney elbow with an inspection port is a bend designed to turn a flue run by 90 degrees while providing built-in service access. It is installed where the route must be “redirected” within a room or boiler area, to bypass a beam/floor structure, or to offset the vertical line relative to a stove or boiler outlet. A turn is a zone where airflow dynamics change and deposits accumulate more actively. That is why the inspection feature is not decorative — it is a practical way to keep the chimney functional without dismantling the system.

The inspection door (hatch) on the body allows quick access for inspection and cleaning: removing soot, checking the condition of the inner walls, and verifying whether there is air leakage or localized build-up in the elbow area. With regular servicing, this reduces the risk of draft degradation and overheating in specific sections. This is especially noticeable when the appliance is used in short firing cycles: more condensate moisture forms, and soot particles tend to stick more readily to the walls.

The element is made of stainless steel AISI 304 (inox 304). This is a widely used chimney-grade stainless steel that performs well in humid environments and resists corrosion and temperature fluctuations. Ø150 mm is one of the most common diameters for residential systems, so the elbow suits fireplaces, stoves, and boilers where stable flue-gas passage and tidy route layout are required.

From an engineering perspective, a 90° turn adds flow resistance. The advantage is a compact build and the ability to route the chimney in confined spaces. The downside is that, if the layout is not designed correctly, draft can drop faster than on straight sections. This is exactly why the inspection version performs better in real use: access for cleaning at the most problematic point helps quickly restore normal flue passage.

The SOLINOX Ø150 elbow with inspection is used in modular stainless-steel systems and is compatible with matching-diameter components (straight pipes, tees, adapters, mounting elements). It is a good fit for projects where the priority is not “install and forget,” but clear serviceability: open, clean, close — and the chimney works predictably again.
