Flue Systems
- Horizontal and vertical flue systems
Remeha has made the installer's job easier with the launch of a low profile flue terminal and a telescopic flue to support the Avanta range. This completes its comprehensive flue range - which also includes vertical flues, plume management systems and balcony terminal kits.
The new low profile flue terminal has two important advantages over conventional terminals. First, it is more aesthetically pleasing - an important consideration if the boiler is to be installed in a kitchen or elsewhere where it will be exposed. Secondly, it reduces the clearance required above the boiler by around 80mm, from 250mm to 170mm, thus increasing flexibility when positioning the boiler.
The telescopic flue can easily accommodate wall thicknesses of 250mm to 450mm with no cutting involved. It is comprised of a tough polyphenylene sulphide (PPS) plastic inner flue and a white painted steel outer pipe, offering clean lines and durability. 
Technical Information
The Avanta Range is designed for room sealed operation and no compartment ventilation is required. The Avanta Range must be installed with the correct Remeha approved flue accessories.
NOTE: The 90° Bend supplied with the horizontal flue kit is not included in any equivalent length calculations.
