Flue gas routing

4.1

Approved flue accessories

The flue accessories for the flue gas systems described in these
instructions are an integral part of the heat source CE approval.
This is why we recommend using Bosch original accessories.
You can find designations and part numbers in the main catalogue.

Installation instructions

DANGER
Risk of poisoning due to carbon monoxide!
Leaking flue gas gives rise to high carbon monoxide values in the
breathing air that pose a risk to life
▶ Ensure that flue pipes and gaskets are not damaged.
▶ When installing the flue system only use the lubricating paste
approved by the system manufacturer.
▶ Check flue accessories are intact when unpacking.
▶ Observe the installation instructions for the accessories.
▶ Crop accessories to the required length.
Make the cut at a right angle and deburr the cut surface.
▶ Apply supplied lubricating paste to the gaskets.
▶ Push the accessory as far as it will go into the female connection.
▶ Install horizontal sections with 3 ° slope (= 5.2 % or 5.2 cm per
metre) in the direction of flue gas flow.
▶ Secure the entire flue with pipe clips:
– Keep a maximum clearance of  2 m between two pipe clips.
– Attach a pipe clip to each elbow.
▶ Check tightness once work is complete.
Flue gas routing over several storeys
If the flue gas routing passes through several storeys, it must be in a duct.
Requirements for installation in an existing duct
▶ If the flue is installed in an existing duct, tightly seal any existing
connection openings using appropriate materials.
