90° chimney elbow with inspection opening SOLINOX Ø150 (inox 316)

The SOLINOX 90° Ø150 chimney elbow with an inspection port made of stainless steel inox 316 is a 90-degree bend designed for harsher operating conditions. It is used when the flue route must be turned within a room, the chimney axis needs to be offset, or structural elements must be bypassed while keeping service access convenient. A turn is a section where soot and ash tend to settle more intensively, so the inspection hatch makes the system not just “installable,” but genuinely easy to maintain in real operation.

The key difference of the inox 316 version is enhanced resistance to aggressive environments. In a chimney, “aggressiveness” is driven less by high temperatures and more by condensate, which mixes with combustion by-products and turns into chemically active moisture. This typically occurs during short firing cycles, in shoulder seasons, when a boiler runs at partial load, when wood is not perfectly dry, and on runs that cool down faster. Grade 316 is commonly selected for exactly these scenarios — where there is a higher risk of accelerated corrosion and a stronger durability margin is desired.

The inspection port allows you to monitor chimney condition without dismantling: open the hatch, assess deposits, clean the channel in the elbow area, and remove dense soot build-up that most often causes draft loss. With regular maintenance, the inspection feature saves time and reduces the likelihood of unpleasant surprises — from smoke odor due to leakage at joints to reduced draft caused by blockage. In everyday use, the benefit is straightforward: the appliance reaches stable operating mode faster, combustion is more consistent, and maintenance becomes predictable.

The Ø150 mm diameter is a standard size for many stoves, fireplaces, and boilers. It provides suitable flow capacity for typical residential systems and enables compact flue layouts. At the same time, it is important to remember the engineering trade-off of a 90° turn: it helps fit the system into limited space, but increases aerodynamic resistance. That is why the “90° + inspection” combination is so practical — if deposits begin to accumulate at the elbow, access for cleaning remains quick and simple.

The SOLINOX Ø150 chimney elbow (inox 316) is compatible with modular components of the same diameter and is used in stainless-steel systems where durability, maintenance without dismantling, and resistance to condensate load are priorities.
