DCI Products ValleyVent - Manual

Valley Installation - Nail one ValleyVent at the bottom of each valley rafter
pointing the 3-ply thick edge towards the valley jack rafter (the two adjoining
ValleyVents should be pointing as close as possible to the center of the valley jack
rafter). Applying the smooth side down, nail in place, install one vent per rafter in
all valley areas, and apply roof sheathing (plywood) over the ValleyVents and nail.
This application ensures air flow through the valley from the soffit to the ridge for
required air exchange. NOTE: Apply a shim spacer at the plywood cut edge in the
valley center if the plywood edge misses the vent strip (use 2.75” X 2.75” pieces of
3-ply ValleyVent or scrap plywood as this shim spacer). Ridge vents are required.
