Installation
For installing the flue gas outlet and air supply materials, refer to the
instructions 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
condensate 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.
