VENT INSTALLATION

Roof Ventilators (Optional)

1. Ventilators may be installed on the roof ridge after the roof sheets are on and before the

ridge roll or peak sheet is installed. The ventilators are ten feet long and usually are installed

at the peak and between two rafters.

2. Cut out the ridge roll or peak sheet to ﬁ t the opening of the ventilator. Ensure that the

opening is cut correctly so the ventilator will ﬁ t properly and provide enough lap over the

opening to prevent leaks. (The roof sheets may need to be trimmed to maximize venting).

3. Place the ventilator over the opening. Use molded rubber outside sealers to ﬁ ll the gaps

between the ventilator ﬂ ange and the roof sheets.

4. Attach the ventilator to the roof sheets with lap tek screws. Screw through the vent skirt to

the tops of the roof sheet ribs.

5. Locate the vent adjusting pull chains as desired. (According to vents instructions).
