1. Determine Location
Place vent as close to the peak of the roof as possible
but below the ridge line. For optimal power, ensure the
vent faces south. Make sure the location is not 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 as 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
Cut out the 15" (381 mm) diameter template printed on
the outside of the package. Place center of template over
hole marked in roof in step one. Use correctly positioned
template to mark a circle. For rafters 24" (610 mm)
on center, mark the cutout as shown (Figure 2a). For
rafters 16" (406 mm) on center, proceed with marking
as shown (Figure 2b).
3. Cut Out Opening and Test Position
Roll back and separate all shingles (if present)
7" (178 mm) from the top and sides of the cutout
area. Be sure that all roofing nails have been removed.
Using a saber saw, jigsaw or handsaw, cut and remove
all roof shingles and deck inside the 15" (381 mm)
diameter circle (Figure 3a). Do NOT cut 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).
Note: For additional weather protection, install a
18" x 18" (457 x 457 mm) piece of GAF Leak Barrier
around the opening. Remove release film and center
the Leak Barrier over hole. Press into place and cut
out the Leak Barrier covering the opening.
4. Fasten and Seal Ventilator
With the position tested, apply a bead of roofing cement
or urethane sealant to the underside of the ventilator's
flashing. Proceed with sliding the ventilator up under
the top shingles, with arrow on the flashing pointing up.
Leave the lower portion of the ventilator flashing on top
of the shingles for maximum weather resistance. Using
roofing nails, fasten the ventilator at all corners of the
flashing and approximately every 4" (102 mm) along
the edge of the flashing (Figure 4). Seal all exposed
fasteners, flashing, stack seams, and loose shingles.
Note: For maximum wind resistance or as required by
building code approval, remove the ventilator hood and
fasten the flashing every 45 degrees, approximately 1"
(25.4 mm) away from the stack wall. Replace ventilator
hood when complete. Seal all exposed fasteners,
flashing, stack seams, and loose shingles.

Note: Excessive application of roofing cement can
cause blistering of shingles.
5. Mount Solar Panel
(Use only if mounting
solar panel on roof deck)
Remove the included solar panel mounting kit from
the carton. The kit contains deck screws, (2) 1/4"-20
bolts, (2) Nylok nuts, and (2) "L"-shaped wings.
®
A. Mark "L"-shaped brackets & top rail mounting
holes. Place the solar panel at least 1.5" (381 mm)
above shingle overlaps. Attach the "L"-shaped wings,
making sure that each bolt is in the center of the slot
in the rail (Figure 5a).
Use a grease pencil or chalk to trace the outline of the
"L"-shaped wings on the shingles and also to mark
both top rail mounting holes.
Note: To avoid possible weather infiltration, do not
place the "L"-shaped wings or the top rails on the
vertical spaces between the shingles tabs.
B. Attach "L"-shaped brackets to roof. Once you have
marked the "L"-shaped wings on the top rail mounting
holes, remove the "L"-shaped wings from the solar
panel frame and lay the panel aside. At the locations
previously traced, carefully pry the shingles and slide
each "L"-shaped wing in the shingle. Align both wings
with the visible portion of your traced outline. While
lifting the shingles, attach both "L" wings to the roof
deck with a provided deck screw (Figure 5b). Press
the shingle back down into place. Apply roofing
cement or urethane sealant under the shingles to
seal them to the roof.
C. Attach top rail bracket. Carefully lift up the shingles
where the top rail mounting holes were previously
marked. Now, align the panel frame between the
installed "L"-shaped wings. Center the slots in the
rails with the mounting holes on the wings. Slide
the top rails under the raised shingles and attach
each rail to the roof deck with a provided deck screw
(Figure 5c). Press the shingles back down into place.
Note: You may have to tilt the panel to access the top
rail mounting holes.
INSTRUCTIONS
Model: ERVSOLAR
Note: Apply roofing cement or urethane sealant under
the shingles to seal them to the roof. Finally, reattach the
"L"-shaped wings to the rails with the provided bolts and
nuts and fasten them securely (Figure 5d).
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 solar panel, loosen the two screws/nuts (Figure 6a)
on the rail mount/linkage connection. Then raise the
panel to 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.
