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.
