Chimney reducer (adapter) S1 is a chimney system element, which is used to connect two pipes of different diameters to change the diameter of the chimney. The sizes of transitions are labelled according to the following principle: for example 180/150, where the first number is the diameter of the seating end and the second number is the diameter of the pipe that will pass through the reducer.

Single-wall systems made of 2 mm thick steel sheet are used for flue gas discharge from fireplaces and solid fuel heaters. These systems are non-condensing and have a maximum operating temperature of up to 1000°C.
Black pipes and fittings are characterised by very fast assembly and high strength. They are rolled on special factory equipment - on one side the landing place is smaller in size, on the other side is larger, which allows assembling the chimney using the ‘one-in-one’ method. The seam is welded by laser welding, which ensures reliability, beautiful aesthetic appearance and convenience in further maintenance. The inner surface is smooth, which does not allow a large amount of soot to accumulate on the walls of the chimney.
After finishing, black heat-resistant paint ‘Senotherm’ is applied to the products. This paint does not smoke when first burning, does not emit an unpleasant odour and due to these properties is used by most fireplace manufacturers.
Black pipes and fittings are installed indoors before entering the flue duct or chimney shaft. When installed outdoors, the chimney should be thermally insulated.
