SPNP Black Steel Chimney Adapter (Diameter Change)
Product Overview & Application
The SPNP black adapter made of DC01 cold-rolled steel is a shaped element of the flue system designed to connect pipes of different cross-sections. This part allows for a correct and gas-tight connection of the pellet stove exhaust (base diameter 80 mm) to the main line or an existing channel of a larger diameter (from 100 to 200 mm). Using such an expanding transition reduces aerodynamic resistance and ensures a stable draft.
Technical Advantages & Design
- Adaptability: The element is available in a wide range of sizes, making it easy to select a configuration to transition from the 80 mm standard to 100, 120, 130, 150, 160, 180, or 200 mm.
- Gas-Tight Sealing: The 80 mm connection side (socket) is equipped with a groove and a heat-resistant silicone gasket, preventing flue gas leaks into the room.
- Environmental Resistance: The 1.2 mm thick DC01 steel offers the necessary resilience to prolonged exposure to moisture and aggressive compounds inside the exhaust system.
- Protective Coating: The exterior surface of the product is coated with Senotherm heat-resistant paint. It protects the metal from corrosion, maintains a neat appearance, and remains odorless during the heating phase.

Installation & Recommendations
The adapter is installed at the point where the channel diameter changes. The 80 mm side connects to SPNP system elements (for example, the 1000 mm flue pipe), and the other side integrates into the continuing channel of a larger diameter. Assembly is carried out by firmly inserting the elements into each other. Ensure all components are installed in the direction of condensate flow. This guarantees that any moisture drains smoothly downwards without penetrating outwards through the joints.
