VENTILATOR INSTALLATION
Note: This ventilator is capable of replacing an existing
120 volt powered attic ventilator. Only a qualified per-
son should remove any electrical wiring in accordance
with local codes and standards.
1. The ventilator is designed to mount behind existing
louvers. Louvers should be mounted in the center of
the gable as high as possible. For maximum efficiency,
the open area of the louver should be greater than the
outlet area of the ventilator. If no louver exists, one must
be installed. Follow the manufacturer’s recommendation
for installing the louver.
CAUTION! When installing louvers or ventilator, do
not remove any existing structural members without
providing alternate support members.
2. Locate the remote solar panel on your roof where the
sun’s exposure is best barring shade (trees, other
buildings etc) at 4:00pm in the hottest month of the year.
The solar panel comes from the factory with 15 feet of
wire. If the desired location of the solar panel is greater
than 15 feet away from the ventilator, an additional 50
ft of 14 AWG (minimum) UL listed or recognized copper
wire may be used.
3. Prior to installation, we recommend setting up the
ventilator and solar panel to verify operation. Take
the fan and solar panel to a location exposed to sun.
Connect the red solar panel wire to the black (negative)
motor terminal and the black solar panel wire to the
red (positive) motor terminal. Removing the cardboard
cover from the solar panel should cause the ventilator to
operate. Place cardboard over solar panel (for safety),
disconnect wire from motor terminals and proceed to
installation instructions outlined below.
4. The ventilator can be installed between studs or placed
over a curb manufactured from 2” x 4” or 2” x 6” wood
(refer to illustration above for curb dimensions). Nail
or screw the ventilator to the wall studs or curb around
perimeter of base every 6 inches.
5. Make sure the outlet of the ventilator is properly sealed to
the exterior wall to maximize the amount of air exhausted
by the ventilator. When installing the ventilator behind
louvers, seal off any louver area not covered by the
ventilator base to prevent air leakage and recirculation.
