Section 4: Installing The Power Vent; Installing The Roof Mounted Power Vent; Venting Layout; Typical Vertical Vent - Montigo H36PVN Installation & Maintenance Manual

Montigo supplies a variety of power venting options The location of
the power vent should be selected and laid out to provide the shortest
possible run to an external wall or through the roof In the event that
the external power vent is not aesthetically acceptable or otherwise
infeasible, an in-line power vent can be used with this and is included
on page 17 of this instruction manual (contact Montigo for Details)
