Tjernlund RVB3 Roof Vent Booster Fan 8504173 (Discontinued) - Manual (Page 3)

3. Temporarily secure the RVB to the underside of the roof sheathing with the included screws through the holes in each corner of the
RVB flange. IMPORTANT: 3/8” screws are short enough to not penetrate the roof deck. Do not use longer screws.
4. Bend the included mounting brackets against a soft radius (rounded edge) to straighten them. If a small kink or bend remains, that
is acceptable as the brackets will retain their strength and further straighten as the mounting nuts are added in Step 7.
5. Bend the end of each mounting bracket on the scored side (a V-shaped hole with be on that side) to create a 1.5” flange and
angled point, (See Diagram E and F).
6. Place one of the brackets over the left hand metal stud on the side of RVB housing. Adjust which notch the stud fits into so that the
bracket is flush against the left hand joist/truss. Use a hammer to drive the angled point into the joist/truss for a temporary hold,
(See Diagram G). Repeat for right hand side of bracket. Install bracket on opposite RVB housing side in same fashion.
7. Firmly secure the RVB to roof joist/truss with provided screws into hole on flange of the mounting brackets, (See Diagram H).
Lock the mounting brackets in place against the RVB by tightening the included nuts onto each metal stud, (See Diagram I).
8. Plug RVB into an electrical outlet or an existing installed RVB.
