bottom of straight edge.
Cut hole as marked and seal around top and sides
with roong cement.
Place locking clamp across seam and tighten with
color-coded machine screw.
Turn bottom of collar clockwise to match roof pitch
number with indicator line on ashing. Place 3
(#10) sheet metal screws through holes that align
with predrilled base holes.
Slide top half of ashing under shingles all the way to
the collar. Apply ½" bead of caulk between the roof
deck and the bottom face of the vent flange. Secure
with (12) 1-1/4" x 3/8" galvanized ring shank nails.
Choose location of turbine by using back of this
page. Center between two rafters and mark hole
to be cut.
Turn top of collar counter colckwise to a level
position.
Position turbine onto the collar, locating the vertical
legs into the collar slots. Install #10 x 1" sheet
metal screws through the vertical legs and into the
extruded holes in the collar. Tighten the screws rmly,
but do knot over-tighten to the point that the screw
strips out.
Using caulk, fasten down any loose shingles.
Using caulk, seal all seams and nails.
After completing installation, check to make sure
the turbine turns freely. The turbine may have
shifted in transportation. If necessary, gently pry
lowest point of turbine upward to remove any
wobble.
