Step 1: Cut a slot in plywood along roof ridge 2" wide (1" on each side). If ridge beam is present, cut slot 1" wide on each side of ridge beam. Allow for a closed area of sheathing 12" at both ends of ridge. |

| Step 2: Place first piece of vent with female end 1" in from gable end and use centering line for proper alignment along peak. Fasten using at least two nails at each end and in middle of section in nail line area (2 1/2" minimum nail length). More may be required on steeper slopes to seat properly. Continue installing additional pieces along ridge sliding female end over male end, aligning using centering line. NOTE: In cold weather, allow a 1/8" gap between vent sections for expansion. |

Step 3: When reaching the other end, the last vent section may need to be cut to length. End plugs are provided every 12" on underside of the product. Measure amount needed to install to within 1" of gable end. Cut that length in from end of vent section and flip around so that end plug is at gable end. Allow male tab from previous piece to slide under last piece and nail in place. |

Step 4: Place first cap shingle over vent so that it overhangs at least 1" over end of vent section. Install with 2 1/2" nails in nail line area as you work your way down the roof. Cut last cap shingle so that it overhangs vent 1" at other gable end. |
