Ultra-Dek® SPECIAL ERECTION TECHNIQUES

RIDGE VENTILATOR INSTALLATION

NOTE

ASBC does not recommend the use of a ridge ventilator on standing seam roof systems. Sidewall or endwall exhaust fans or other ventilating methods should be considered. These details are for your convenience only. Only a 9" 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.

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. On 5:12 and 6:12 roof pitches see vent manufacturer’s special instructions for the installation of the vent skirt. The end cap is now ready to receive the end skirt.

CAUTION
The end skirts shipped with ridge ventilators will not work on a standing seam roof. You must order a "Ridge Vent SSR Kit" for each ridge ventilator to be installed on Ultra-Dek® roofs. This kit contains two end skirts which must be installed to support the ventilator.

Reposition 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 Fastener #4 in four places.
