INSTRUCTIONS TO INSTALL A SOLAR ATTIC FAN VENTILATOR
Tools and Materials Required.
- 1/4″ Drill Bit
- Solar Panel
- 4 Z brakets (solar panel)
- 15 feet of wire
- Solar Fan
1. Install the 4 Z brackets provided with the kit on the solar panel as shown in the picture below.
2. Install the Solar Panel securely on the roof where it gets the most sunlight through out the day.
3. Install the Fan in the gable securely so the hot air from the attic would vent out.
4. Connect the wire from the Solar panel to the extra 15 feet of wire and Fan as shown below in the picture.
Instructions to Install Solar Roof Mount Fan
TOOLS AND MATERIALS REQUIRED
1/4″ Drill Bit
Sabre Saw or Keyhole Saw
Ruler / Tape Measure
Pencil, Marker or Scribe
Pry Bar (to remove roofing nails)
5/16″ Socket and Extension
Galvanized #10 x 1″ Pancake Head Wood Screws
1. Solar panel
2. Roof Vent solar fan installed inside the vent.
3. Four metal brackets
4. Screws to install the brackets to the roof 20
5. Screws to install the secure the brackets to the solar panel 10
1. Determine the sun’s best exposure location on your roof barring shade (trees, other buildings etc.) at 4:00pm in the hottest month of the year. Generally, we recommend a point located 24” – 36” on center below the roof peak and centrally along the ridgeline on the south, southwest, or west side of the home.
2. Prior to installation, we recommend setting up the ventilator to verify operation. Take the ventilator to a location exposed to sun. Secure cardboard in place over solar panel (for safety).
3. Working from the inside of your attic, find the desired ventilator location and mark a spot halfway between rafters at a point that is 24” – 36” below the roof ridge.
4. Drill a guide hole through the roof at this mark.
5. From the roof side, using the guide hole as the center point, use a nail and string to scribe a 10″ diameter circle on the shingles. Note: If replacing an existing ventilator, the hole diameter may be larger than 10″. This is acceptable provided the roofing material overlaps the ventilator by at least 2” on all sides. 6. Cut out the shingles inside of the circle.
7. Using the same nail and string shown in step 6, scribe a 9” diameter circle on the black paper or roof decking. Note: if replacing an existing ventilator the hole diameter may be larger than 9”. This is acceptable provided the ventilator base is adequately supported by the roof decking.
8. Drill a large starting hole for the sabre saw just inside of the line or the 9″ circle created in Step 7
9. Cut out the roof board(s) inside of the line.
10. For proper removal of roofing nails, draw a 27″ square, centered around the hole. Remove nails holding shingles down from top two-thirds of square
11. Apply a large bead of roofing cement in the molded groove on the bottom side of ventilator base. Make sure the arrow on the ventilator base is pointed toward the roof ridge. Start two-thirds of the way down from the top of the 27” square and slide the ventilator base under the shingles. Do not bend the shingles any more than necessary. Center the ventilator base over the hole.
12. Make sure the ventilator base is parallel to the roof ridge, carefully lift shingles and screw base securely to the roof using galvanized #10 x 1″ pancake head wood screws. Screw all corners and around perimeter of base every 6 inches.
13. Using a good grade of roofing cement material, seal shingles and all screw heads. DO NOT seal the bottom edge of the ventilator base.
14. Position the ventilator dome so the top points toward the roof ridge.
15. Install the four metal brackets provided to hold the solar panel on top of roof vent with the screws provided to match the size of the solar panel 24.8″ x 26.4″ for 60 watt solar panel.
16. Connect the two wires from the solar panel positive and negative to the two wires from fan which are coming out of the vent securly. (black wire from the fan is negative)
17. Install the solar panel on to the brackets and secure it with the screws provided.
