RENOFAST Single-Wall 45° Chimney Tee
Product Description
The RENOFAST tee with a 45-degree entry angle is an element for connecting the heating appliance to the main vertical chimney shaft. Thanks to its inclined design, it ensures the smoothest possible entry of flue gases into the shaft.
Unlike the standard (90°) tee, the 45° model creates significantly less aerodynamic resistance. This is critical for open fireplaces, solid fuel boilers, and any systems where ensuring stable and powerful draught is essential.
Advantages of Using a 45° Tee
- Ideal Aerodynamics: Smoke does not hit the rear wall of the pipe at a right angle but flows smoothly upwards with the stream. This reduces turbulence, improves flow speed, and minimizes soot deposition at the junction.
- Custom Solutions: If your installation scheme requires a specific angle (e.g., 30° or 60°), we can manufacture such an element upon request.
- Fuel Type: Optimized for solid fuel (firewood, coal). Excellent for relining brick channels where maintaining flue gas velocity is important.
- Reliability: Manufactured from acid-resistant stainless steel AISI 304L / 316L (0.6 mm thickness), resistant to high temperatures (T600).

System Configuration Recommendations
For proper installation of the connection unit, you will need:
- Sealing: Angled connections experience increased thermal stress. To guarantee gas tightness, use heat-resistant sealant when assembling joints.
- Maintenance: Since cleaning the vertical shaft through an inclined tee is more difficult, it is recommended to install a separate inspection tee with a hatch below it.
- Condensate Drainage: A condensate collector or a blind cap must be installed at the base of the chimney (under the tee).
- Support: The weight of the chimney must rest on a wall bracket or a load-bearing platform, not on the boiler outlet.
