Choose a location for your bathroom exhaust fan includes two practical problems: where is the fan most will simply get on with their task, and where the pipelines can be executed, is the most efficient.
Follow the moisture
First, the fan should be is in the area of the bath, exposed to the most moisture. This is usually the area above the bath or shower. The aim of the exhaust fan is primarily for the removal of wet, damp air that can cause mold or moisture damage, and your bathroom is the exhaust gas the most quickly, if you position the fan over the range, where most of the moisture.
You can run the fan directly above the bath or shower tray, but it is enough to position it anywhere in the vicinity of the bathing beach. If the bathroom has both a bath and shower or a shower and a Spa bath, should go to the fan, somewhere in between the two devices.
If the bathing area is in a separate room, the room needs to have its own fan, and you want to is perhaps another fan for the main bathroom area, or where the toilet.
You Plan Your Vent Piping Route
Next, the bathroom plan exhaust fan location, so that the channel has the shortest and most direct route to the roof or wall vent. It is best when the fan is within six feet of the outside vent cap, where all the moist air escapes to the outside, with the straightest route possible. Multi-channel runs to make the fan less effective and increase the likelihood of condensation on the inside of the channel.
You exit the channel through the roof or gable wall, or a soffit (if you have a special vent cap).
Avoid venting through a wall, under a soffit (eave overhang of the roof), as these include the moisture, the overhang below the eaves.
Check the attic
Head up to the attic, with a tape measure to scout your bathroom fan location exhaust air from above the ceiling. Measure from one outer wall to find a plumbing vent pipe, or electrical boxes in the ceiling of their warehouse.
(It also helps, a helper at the bottom measure in the bathroom, communication measurements by mobile phone).
Make sure you install the fan between two ceiling and that there is enough room to make the transition from the fan housing to the channel. Also make sure that the vent-cap as well as free from obstacles and trouble areas of the roof—things like roof valleys, roof Windows, fireplaces, or furnace or water heater vents.
