Cor-A-Vent Product Guide

Be careful not to touch knife blade. Always cut in a direction away from yourself. Wear proper hand and eye protection. 12 Square inches Net Free Vent Area per lineal foot. 20' long x 9" or 11" wide x 5/8" thick. For use on roof pitches 3/12 - 16/12. Call our technical department for any special application questions. Important notes: COR-A-VENT ridge vents should always be installed with soffit/eave/intake vents of equal or greater area. All other vent openings (except soffits) should be closed off. The air passage way or “Ventilation Chute” between the inlet (soffit/eave/intake) and the outlet (ridge) vent must not be blocked or restricted. COR-A-VENT products meet or exceed all nationally recognized building codes for ventilation. 3. Beginning at end of ridge, apply vent with minimum 1¾" nails (2 coils provided in box) following “NAIL HERE” guides along vent cap. Only apply nails within the area between leg cavities – DO NOT apply nails outside of “NAIL HERE” guide marks. Vent may be power nailed or hand nailed. Do not overdrive nails. Apply first four nails (two on each side), then remove colored band to unroll rest of vent. Continue to apply according to marked guides. 4. For runs longer than 20 feet, additional vent rolls can be applied. Line up end of additional vent roll with previous roll by overlapping at offset lip. Follow Step 3 to apply rest of vent. 6. Center shingle cap on vent and nail along “NAIL HERE” guideline. Continue applying caps until all vent is covered with ridge caps. Do not overdrive nails. Nail head should be flush with top of shingle, without indenting it. Pre-forming caps in cold weather helps avoid cracking. Revolution Installation Instructions 1. Measure a 3" slot, 1½" each side of ridge centerline. This allows for a 2x ridge board or smaller. Snap chalk lines the entire length of the ridge. Cut slot with circular saw and clean out debris. Set saw depth so as not to cut roof rafters. Stop slot 12" short of any ridge end, intersecting ridge or obstruction (such as a chimney). 2. Cut clear band around roll, leaving colored band to hold all but the starter section together. Vent installs with legs down and flat cap on top. 7. To close off ends of vent, fold over a section of End Plug material (2 per ctn.) and pinch together (see inset). Insert End Plug material between vent legs. Once seated properly, seal in place with flexible caulk. INSERT INTO OPEN ENDS 5. For shorter runs of vent, trim areas provided every 12". Cut with utility knife, snips or saw, taking care to follow recognized manufacturers’safety procedures for each. © 2009 COR-A-VENT, Inc.
