INSTALLATION INSTRUCTIONS

STV51 SBV603 SBV61 SBV40GV

These roof-mounted units are designed for attics of average size and operate most eciently 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.

LOCATING THE STATIC VENT

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 prole 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.

CUTTING THE HOLE

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.

INSTALLING THE VENT

3. With the top of the unit parallel to the ridge line, slide the ange up under the shingles.
It may be necessary to remove some additional roong material and fasteners around
the unit for it to t snugly. Select an appropriate roong sealant for the construction
material (refer to chart below), and apply a generous amount between the ange and
shingles, approximately ½” from the outer edge. Secure with approved roong nails, or
staples with a minimum 1” penetration, and a maximum 4” space between each nail or
staple.
