• Ensure drip edge has been installed.
• Do not cut slit within 12" of whatsoever side or valley/wall intersection, or any other obstruction.
• Do not cut into the rafters.
• Ensure insulation or other obstructions are non blocking the menses of air extending from the cut slit to the roof'south ridge, or other exhaust devices.
• Properly sized ridge or off ridge exhaust vents are required.

STEP 3

Lay the 3' piece of SmartVent™ even with the baste edge and at the roof rake drip edges.

• Starting 2" from each end of the SmartVent™ slice, nail the SmartVent™ to the roof decking at the meridian edge with 4 nails spaced evenly.
• Smash the bottom with four nails matching the spacing from the summit row of nails along the smash line.
• Each section requires a total of viii nails (nails should exist a minimum of 1 ½", enough to penetrate through the roof decking).
