Step 5
Thereafter, the installer will bracket the wires to the ceiling, where he will tap the wires to the wires of the ceiling light. This way, the ventilation fan will be switched on when the light gets turned on. If cases whereby customers do not want to tap it to the ceiling lights, they can have the alternative of tapping it to the water heater as well, whichever is more convenient. In some occasions, customer may even request to fix up a switch of its down for just the powering of the ventilation fan. |
