6.5.5 Additional guidelines

For installing the flue gas outlet and air supply materials, refer to the in­
structions of the manufacturer of the relevant material. If the flue gas
outlet and air supply materials are not installed in accordance with the
instructions (e.g. not leakproof, not properly bracketed), this can result in
dangerous situations and/or physical injury. After installation, check at
least all flue gas outlet and air supply parts for tightness.
Direct connection of the flue gas outlet to structural ducts is not permit­
ted because of condensation.
Always clean shafts thoroughly when using lining pipes and/or an air
supply connection.
It must be possible to inspect the lining duct.
