RIDGE VENTILATOR INSTALLATION

PREFORMED FOR A 1:12 PITCH

NOTE Sidewall or endwall exhaust fans or other ventilating methods should be considered. Chief does not recommend the use of a ridge ventilator on Standing Seam roof systems. These details are for your convenience only. A nine inch ridge ventilator can be used with this SSR system. Do not use ridge ventilators on any roof over 200' in width or with a slope less than 1:12 or greater than 6:12.

SIDE SKIRT

Turn ventilator over and place gently on its top. Note that the end cap is pre-formed for a 1:12 roof pitch. The five bench mark dots represent 2:12, 3:12, 4:12, 5:12, and 6:12 roof pitches. Draw a line between indicated corners and the appropriate dot for the roof pitch. Cut and remove that portion of the end cap. The end cap is now ready to receive the end skirt. Position the flat end skirt over the end cap, aligning center of end skirt with center of end cap. Mark the perimeters of the end skirt on the side skirts of the ventilator. Remove end skirt and apply Sikaflex-201 to the side skirts of the ventilator, just inside the marks. This will prevent water from being blown between the two pieces and entering the building. Reposition flat end skirt onto end cap. Be sure the down-turned angle of the end skirt is inside of and up against the end cap. Attach end skirt to ventilator end cap with 1/4"-14 x 7/8" WT fasteners in four places.
