Additional guidelines
Installation
For installing the flue gas outlet and air supply materials, refer to the in
structions of the manufacturer of the relevant material. After installation,
check at least all flue gas outlet and air supply parts for tightness.
Warning
If the flue gas outlet and air supply materials are not installed in
accordance with the instructions (e.g. not leak-proof, not correctly
bracketed), this can result in dangerous situations and/or physical
injury.
Make sure that the flue gas outlet pipe towards the boiler has a sufficient
gradient (at least 50 mm per metre) and that there is a sufficient conden
sate collector and discharge (at least 1 m before the outlet of the boiler).
The bends used must be larger than 90° to guarantee the gradient and a
good seal on the lip rings.
Condensation
Direct connection of the flue gas outlet to structural ducts is not permit
ted because of condensation.
If condensate from a plastic or stainless steel pipe section can flow back
to an aluminium part in the flue gas outlet, this condensate must be dis
charged via a collector before it reaches the aluminium.
