STATIC ATTIC VENTILATORS
INSTALLATION INSTRUCTIONS
Models: STV51, STV51GV, SBV603, SBV603GV, SBV61, SBV40GV
These roof-mounted units are designed for attics of average size and operate most efficiently if air intakes are located
around the eaves. For larger attics, use two or more units. An adequate amount of air intake is required for each unit.
1. Place the unit on top of the shingles, as close to the center of the roof and as near to the
ridge line as possible. For neat installation, the low profile housing on the unit should be
visible only on one side of the roof. This will require that the unit be moved down
slightly from the ridge. When this position is established, locate a centerline directly
between two rafters and drill a hole through the roof, from the inside. This hole will be
used as a center for the following operations.
2. Draw a circle or square on the roof (refer to chart below for opening size), using the
drilled hole as the center, and cut the appropriate size hole in the roof.
3. With the top of the unit parallel to the ridge line, slide the flange up under the shingles.
It may be necessary to remove some additional roofing material and fasteners around
the unit for it to fit snugly. Select an appropriate roofing sealant for the construction
material (refer to chart below), and apply a generous amount between the flange and
shingles, approximately ½” from the outer edge. Secure with approved roofing nails, or
staples with a minimum 1” penetration, and a maximum 4” space between each nail or
staple.
