6. Use a pencil to trace a line around the junctions box so you’ll know where to cut through the sheet rock with the jig saw (figure A).
7. Drill a hole in the traced area to make an entering point for the jigsaw blade. Use the jigsaw to cut the opening for the junction box (figure B).
8. Mount the junction box to the bottom of a 2" x 4" board, then slip the 2" x 4" down, in between the ceiling joist so the box is seated in the opening. Secure the 2" x 4" in place with screws.
9. Tap into an electrical source by running a wire from the supply box to the junction box.
10. Stick the end of the wires through the junction box, and attach the wires together with the corresponding colors. For example, connect white wire to the white wire, black wire to black and green to green or bare. Twist the wires together in a clockwise motion and cap off tightly with a wire nut. The kit may also come with brown wires that which are for the lighting portion of the fan.
11. Lift the entire motor piece to hook into the down rod brackets. Tuck all the wires in the junction box or housing plate. Mount the housing plate by screwing it to the down rod housing bracket.
12. Attach the fan blades with screws to complete the fan. The blades can be switched to spin in either a forward mode that blows rising hot air down during the winter or a backward mode to pull the warmer air up and cool off a room during the summer months.Whole House Fan
Keep your home comfortably cool with an energy efficient and quiet belt driven whole house fan. By removing the hot air from the house, a whole house fan restores your house with fresh air from outside.
Steps:
1. For the best results in a one-story house, position the fan in the center of a hallway ceiling. If your house is two-stories, install the fan system in the ceiling at the top of a stair well.
2. Turn off the power at the main circuit breaker before removing and replacing any old or existing whole house fan system.
3. Position the new fan base over the top of the joists at the rough opening where the old fan system was removed. If there was not previously a fan system in place, use a template to measure and cut an opening for the new system.
4. Toenail the fan base in place.
5. Re-wire the motor by connecting the matching wires together in a clockwise twisting method. Secure the wires with a wire nut.
6. Before screwing the louvered shutters in place, make sure they open and close with ease.
7. Use caulking to seal any holes gaps around the shutter frame.
Exhaust Fan
Stagnant air in the attic can reach over 150 degrees during the warm months. The higher the attic temperature rises, the quicker the bordering rooms below heat up, as well. To keep your home at a desirable temperature, install a powered exhaust ventilation fan.
Steps:
1. Since heat rises, warm air can be purged from your house through a gable vent. The ideal location for a gable vent is about 2' to 3' from the roof ridge and 14’ from the side of the house.
2. Use a tape measurer to find this location inside the attic. If the location is on or close to the roof rafters, adjust the location to fall between the two roof rafters, and mark with a pencil. Drill a hole up through the interior ceiling out through the exterior roof.
3. Trace the 14' diameter template for the exhaust fan hole about 1" below the lower edge of a roofing shingle with a marker.
4. Use a reciprocating saw to follow the template design and cut an opening through the roof.
5. Loosen the shingles along the top edge of the hole with a putty knife to slide the edge of the fan beneath.
