1. Determine Location

Place vent as close to the peak of the roof as possible but

below the ridge line. Be sure the unit faces to the south for

optimal power. Make sure the location is not be shaded by

trees or other nearby structures during the day (Figure 1a).

Measure from the peak of the roof to the midpoint of the

solar power vent (Figure 1b). Transfer this measurement

into the attic and mark the location inside the attic, centered

between two rafters, and drill a hole (Figure 1c). Put an

object, such a pencil or nail, through the hole to mark it on

the outside. Note: Single units should be centered. If multiple

units are used, space evenly over the length of the ridge.

2. Mark Opening

top and sides of the cut–out area. Be sure that all roofing

nails have been removed. Using a saber saw, jig saw or

hand saw, cut and remove all roof shingles and deck inside

any rafters. Test the final position by inserting the top half

of the unit flashing under the rolled shingles. Trim shingles

as necessary (Figure 3b).

4. Secure And Seal Unit

Remove the unit from the test position and liberally apply

roof cement to the bottom side of the flashing. Align the

unit and slide it under the shingle corners. Be sure that the

arrow marked in the flashing points up to the roof peak.

Secure the unit into place with galvanized roofing nails at

the sides of the flashing (Figure 4). Finish by using roof

cement to seal all flashing and shingle edges, as well as

nail heads and stack vertical seam. Press all raised shingle

edges back into position. Warning: Using excess roof cement

may cause blistering in the roofing shingles.

5. Mount Solar Panel (Use only if mounting Solar panel

on roof deck) Remove the included solar panel mounting kit

(Figure 5b). Press the shingle back down into place. Apply

roofing cement under the shingles to seal them to the roof.

back down into place.

Note: You may have to tilt the panel to access the top rail

mounting holes.

CAUTION: THIS UNIT IS WIRED AT THE FACTORY AND

IS READY TO RUN. THIS FAN AUTOMATICALLY STARTS

WHENEVER THE SOLAR PANEL IS EXPOSED TO A LIGHT

SOURCE. ALWAYS EXERCISE CAUTION WHEN IN THE

VICINITY OF THE FAN.

6. Adjust Solar Panel

When adjusting the solar panel, be sure to tilt or rotate the

panel to maximize direct exposure to the sun. To tilt the

desired location and re-tighten (Figure 6b).

To rotate the solar panel (for hood mount installations only),

loosen four wingnuts, rotate panel to desired position and

tighten securely.

Note: The optimum angle can be calculated by using the

approximate latitude of the house plus 20 degrees. The

solar panel should face south, when possible.
