Mount Garret Exhaust Fans
Mounting Garret exhaust fans aids you in reducing your central's carbon footprint by effectively reducing your inland's vigour consumption. It extremely reduces your cooling costs by circulating the evening's frosty breezes complete your local. An Garret fan consumes less power than a central air conditioning transaction and effectively reduces the internal temperature of your at ease and increases advanced air circulation. It may not sound allying a do-it-yourself project as it involves creating an opening in your roof or gable and attaching the fan to your electrical action, however anyone can determine it.
Instructions
Attic Exhaust Fan Gable Mount Instructions
1. Degree your existing gable vent with a measuring tape. Compare that measurement to the thickness of the Garret exhaust fan. Identical measurements beggarly you determine not chalk up to adjust the proportions of the opening in the gable.
2. Remove the screws or nails that secure the mature vent to the existing framing with a claw hammer or a screwdriver. Lift the gable vent outside of the opening.
3. Centre the front of the automatic Garret exhaust fan shutter over the vent hole. Place a level along the top of the shutter and view the level tube to verify that the shutter is level. Trace the outline of the shutter onto the gable with a pencil. Visually inspect the area around the old gable vent to verify that no electrical wires, or heating or plumbing pipes will obstruct the attic exhaust fan placement.
Wrap the bare ground wire around the green terminal in the box. Wrap the white circuit wire around the white fixture lead. Wrap the black circuit wire around the black fixture lead. To make the opening larger, cut away the siding around the opening with a reciprocating saw.
5. Place the shutter into the opening. Align the shutter with the outline that you drew previously and fasten it in place by screwing evenly spaced 1-inch wood screws through the shutter frame into the surrounding boards with a screwdriver. Cut the applicator tip of a tube of acrylic caulk along the 3/4-inch bead line and use it to apply a 3/4-inch bead of acrylic caulk along the outside perimeter of the shutter.
6. Hammer a 2-inch by 4-inch board (blocking), equal in width to the shutter, in place along the bottom of the shutter with 3-inch galvanized nails. This blocking will give added support to the fan mounting panel.
7. Cut a piece of 3/4-inch plywood 1/2 inch larger than the outside shutter measurement with a table saw to create a mounting panel.
8. Trace the outline of the circular vent hole onto the center of the plywood mounting panel that you just cut out. Most fans will come with a template to aid you in tracing the correct diameter circle. If your fan does not have a template, create one by placing a piece of paper under the fan vent and tracing its shape onto the paper with a pencil.
9. Install a 3/4-inch drill bit in your drill and use it bore a hole through the plywood along the vent hole cut line. Insert the blade of your reciprocating saw through the 3/4-inch hole and cut along the circular line. Place the template on the roof aligned with the starter hole. Place the blade of your reciprocating saw through the drilled hole and use it to cut out the circle.22. Spread a heavy coat of roofing mastic on the back of the fan flange with a paint scraper.
11. Have a helper hold the fan and mounting panel level behind the shutter and nail the mounting panel to the gable framing with 3-inch galvanized steel nails.
12. Shut down the breaker that powers the attic lighting, and count the number of lights and electrical boxes that have no power with the breaker shut down. Multiply the number of boxes and lights without power by 1.5. If the resulting number equals five or greater and the circuit you shut down is Fifteen amps or the number equals eight or greater and the circuit you shut down is Twenty amps, contact an electrical service professional to run a 14-2 w/g cable into the attic and complete the attic fan installation. If the resulting numbers indicate that the circuit breaker amp capacity will support the fan, place the fan thermostat box directly in the path of the fan airflow and screw it to the plywood mounting panel with 1-inch wood screws.
13. Disconnect the 14-2 w/g cable from the electrical fixture closet to the gable and set the fixture aside.
14. Place a 5/8-inch drill bit in your drill and use it to bore holes in the center of the attic rafters between the open fixture box and the gable wall.
15. Run 14-2 w/g cable through the holes between the open box and the fan. Leave Eight inches of slack in the cable at the open box and the fan thermostat box and staple the new cable in place.
16. Strip Eight inches of wire insulation from the end of the wire closet to the fan with wire strippers.
17.Attach a box connector to the 14-2 w/g cable. Remove the thermostat box cover and feed the cable wires into the thermostat box. Tighten a fastening nut onto the box connector.
18.4. Adjust the existing gable opening to the size needed (5/8 inch smaller than the outside perimeter of the shutter) for your automatic attic exhaust fan shutter flange. To make the opening smaller, create a flat surface to mount the flange by hammering 1-inch by 3-inch boards to the old frame opening. Screw twist connectors over the white and black fixture leads. Replace the box cover and set the fan thermostat to One hundred five degrees Fahrenheit.
19. Reconnect the open fixture by wrapping an 8-inch-long black lead wire around the brass terminal screw and an 8-inch-long white wire around the silver terminal in the open fixture box and joining the like colored wires from the 14-2 w/g cable with the lead wires with twist connectors. Replace the fixture mounting box on the ceiling or wall.
Attic Exhaust Fan Roof Mount Instructions
20. Locate the best place to position your attic exhaust fan. Trace the outline of the circular vent hole template onto the attic roof and drill a 5/8-inch hole somewhere along that line through the ceiling of the attic and the roofing material with a 5/8-inch drill bit installed in your drill.
21. Locate the starter hole on the roof. Remove the center waste to create the airway opening.10. Hold the fan mounting bracket on the plywood with the attic exhaust fan centered over the airway opening and screw the fan mounting bracket onto the plywood mounting panel with the supplied mounting bracket screws. Locate the up/down orientation marking on the exhaust fan supports and mark the top of the plywood mounting panel accordingly.
Position the attic exhaust fan flange under the surrounding shingles and over the hole and press it in place against the roof.
23. Position the fan thermostat box (regulator) within the hole, the fan over the flange and screw the fan in place with the supplied screws. Secure the fan to the roof by nailing a roofing nail through each corner of the flange. Cover the nails with a thick layer of roofing tar.
24. Go back to the attic, remove the fan thermostat cover and nail it to a nearby stud with 2-inch galvanized nails.
25. Following steps Twelve through Nineteen in Section 1.
