Reducing chimney tee DN 100/113 for boilers with an open combustion chamber SJBT90R100113

Chimney tee made of acid-resistant sheet metal

Product intended for gas and oil boilers with an open combustion chamber, where aggressive combustion products can lead to corrosion. Instead of standard stainless steel, it is made of acid-resistant sheet metal — which increases its resistance to acids contained in flue gases, especially during prolonged use and at lower temperatures where condensation is more frequent.

Installation is simple: the tee connects components of the chimney system with a diameter of DN 113, without the need for additional adapters. It is a standard component for single-wall systems, which are widely used in installations for liquid fuel and gas boilers. The 90° angle allows for a natural change in the direction of flue gas flow, minimizing flow resistance and the risk of soot deposition.

The weight is 0.57 kg — facilitating transport and installation, even at high levels. The material is uniform: there are no plastic elements, rubber gaskets, or other components with different coefficients of thermal expansion. The entire unit is welded or formed from a single sheet — meaning: there are no weaker points that could loosen under the influence of temperature.

The component has a diameter of DN 113 and is designed for use with chimney systems of the same diameter.
