Reduced Vertical Installation
(Available on Linear Power Vent models ONLY)
It is possible to reduce vertical vent runs from 5"/8" venting to 4"/7"
venting. Reduced vertical venting may only be used when the Linear
(In-line) Power Vent is required. This is commonly due to longer than
normal vent runs or unusually long horizontal Vent runs.
