Installation Instructions for FAMCO Continuous Ridge Vent

1) Cut underlayment and roofing materials back from peak of ridge by (2" each side for 4" vent) and (4" each side for 8" vent). This will allow direct air fl ow from the attic. DO NOT cut 24" from either end of ridge to allow for soffit (eave overhang).

2) Starting 1/8" from one end of ridge, lay two strips for ridge vent down end to end. Place and center one bottom connector under the butted ends. The two side pieces of the bottom connector should be bent down to approximate the slope of the roof.

3) Screw first piece into place starting at the end of the ridge (use neoprene washer screws). Do Not install the last set of screws into this piece at present (the connector needs to be adjusted). Make sure that the bottom connector is centered between the two pieces and install the last set of screws close enough to the end to penetrate both the ridge vent and the connector. Set the screws approximately 1 1/2" from the bottom edge of ridge vent.

4) Set second piece of ridge vent into place being sure to leave approximately 1/8" space between the two. Screw this piece into place leaving the last set of screws out as in #3. Continue this process until all pieces are in place. The last piece may have to be cut to length but this is easily done with a hacksaw and metal cutting blade.

5) Each open end should now have an end cap installed. This is done by inserting the end cap into the end of the ridge vent. The end cap is designed to be friction fitted but if it does not stay in place it can be held in place using a small sheet metal screw or some silicone caulk on the edges.

6) Caulk all butted joints using a high grade of waterproof caulk. While the caulk is still wet set the top cap into place being sure to center it over the butt joint. Use small sheet metal screws to hold it secure.

NOTE: If the roofing material is formed metal you may be advised by your metal supplier to use closure strips to seal under the ridge vent flashings. Be sure to secure ridge vent only on the high points of formed metal roofing materials.
