• Install on pitches 3/12 to 16/12. See page 4 for pitches greater than 12/12.
• Must be used with an equal or greater amount of soffit vent.
• 1-1/2 inch slot required at ridge.
• Can be installed with a nail gun. Compressor pressure should be between 90 and 100 psi.
• Must be installed with minimum nail size of 1-3/4 inches.
• If installing on dimensional or architectural shingles on new construction, leave felt underlayment about 6 inches long at roof ridge and fold back under the vent. The vent should be installed on top of the felt over the shingles. If re-roofing, caulk between low areas of shingle and underside of ridge vent.

Step 1:

Cut a slot in plywood along roof ridge 1 1/2 inches wide (3/4 inch on each side, see detail on page 5). If ridge beam is present, cut slot 3/4 inch wide on each side of ridge beam (see detail on page 6). Allow for a closed area of sheathing 12 inches at both ends of ridge.

Step 2:

Place first piece of vent with female end 1inch 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 (1 3/4 inch 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 inch 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 inches on underside of the product. Measure amount needed to install to within 1inch 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 1inch over end of vent section. Install with 2 1/2 inch nails in nail line area as you work your way down the roof. Cut last cap shingle so that it overhangs vent 1inch at other gable end.

Helpful hints:

• Optionally, you may install cap shingles on each piece as you go along, taking care to assure proper placement.

• Lines across top of product indicate where the end plugs are on the underside (every 12 inches). There is no need to flip the last piece if you measure and plan ahead to install on an even foot increment.

• The nail line area is completely free from obstructions except where the end plugs are. By using the end plug indicators on top of product, you can easily avoid nails through the end plugs.
