INSTALLATION INSTRUCTIONS
Horizontal Vent Installation
To extend the exhaust common vent trunk line and the
air intake common vent trunk line to outside, additional
InnoFlue® PP are required. Refer to "Parts list" for
additional information. No other vent material is
permitted for common venting.
Once the vent terminal location has been determined,
make a hole or holes through the exterior wall to
accommodate the vent pipes, Vent pipes must exit
exterior wall horizontally only. Connect a bird screen or
a termination tee to the common venting on the exterior
of the building.

vent termination and an air intake common vent
termination have a minimum 36 inches (91 cm) edge
to edge clearance and a maximum 20 feet (6.1 m)
edge to edge clearance. Consider other clearances
as well. Refer to page Horizontal Vent Termination and
Horizontal Vent Considerations Vent for additional
information.
Hole should be 0.5" (1.3 cm) or larger than vent pipe

Extend the exhaust common vent/air intake common
vent and terminate 12"-24" (31cm-61cm) beyond the
exterior of the building. Support vertical and horizontal
runs as described on page Horizontal Vent Termination
and Horizontal Vent Considerations Vent. Vertical
supports are required every 78" (2 m).

Completely seal where the common vent passes
through the wall plate and where it is attached to the
structure. DO NOT support, pin or otherwise secure the
common vent in such a way that restricts the normal
thermal expansion and contraction of the common vent.
