5.16 Installing the vertical roof duct
5.16.1 Installation instructions
Danger!
Risk of poisoning due to escaping flue
gas and risk of material damage due to the
roof duct shearing off.
Snow and ice sliding down pitched roofs may
break off the vertical roof duct where it exits
the roof.
▶ In regions where heavy snow
falls/extensive ice formation can be ex-
pected, install the vertical roof duct close
to the ridge or install a snow guard mesh
above the roof duct.
The vertical roof ducts can be shortened under the roof.
However, to ensure that the fixing bracket is secured tightly,
the lengths must still be sufficient.
▶ Shorten the flue pipe and the air pipe by the same
amount.
