Vertical vent termination installation
IMPORTANT
The vertical vent termination must not
be shortened outside the roof,
otherwise the overall length will be
shorter than required.
1. Install the vent termination for
sloped or flat roof collars in
accordance with the manufacturer's
instructions.
2. The vent termination should be
placed from above on the sloped or
flat roof collar. In the case of system
size 80/125 (5" system), ensure that
the adaptor (g) supplied with vent
termination is installed.
3. Connect vent pipe from below.
