Ultra-DekŪ SPECIAL ERECTION TECHNIQUES

RIDGE VENTILATOR INSTALLATION
(CONTINUED)

After Tri-Bead tape sealer has been applied to top of outside closures, install ventilator in proper location. Be sure to center in opening. Attach ventilator to outside closures with Fastener #4 on 6" centers. Use urethane sealant to seal between the outside of the ventilator and 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-DekŪ roofs. This kit contains two end skirts which must be installed to support the ventilator.

Install the ridge flashing as in Step 14, except for those pieces on either side of ventilator. These will lay on top of, and seal to, the ventilator end skirt with a ridge end cap. Use Tri-Bead tape sealer to seal the ridge end cap to the ridge flashing and the end skirt. Use Fastener #4 to install the end cap. Six fasteners are required to tie the end cap to the ventilator end skirt. Eight fasteners are required to tie the end cap to the ridge flashing.

For continuous ventilators, install end skirts on both ends of the first ventilator and one end of all following ventilators. Attach ventilator to outside closures as outlined above, Install an additional Fastener #4 through the corner of the side skirt and into the end skirt.

Do not connect more than 4 vents to the same linkage.
