        Bathroom fan is the most essential device every home need to install in their bathroom. Everyone needs one!

Bathroom fans remove shower and bath humidity.

This article will teach you how to install your fan. Bathroom fan installation is not an easy DIY installation, so you have to get ready for work.


STEP ONE      

Do your CFM Arithmetic:

What is CFM? CFM = cubic feet per minute. To calculate CFM, you simply have to know your bathroom dimension. It is given as (Length x Weight x Height) Divide by 7.5 equals to CFM. The value of your bathroom CFM say 120 or 210 is a guide to the rating of bathroom fan you would need to purchase. It is printed on the package.



Get the tools ready and choose the sound rating:

You wouldn’t like a noisy fan in your bathroom. Choose between (0.5-6) sones. 0.5 ratings is very quiet while 6 rating is noisy.

You will need tools like duct tape, pencil, screwdriver (flat), saw with cutting blade, driller, twister and wire connector.



Decide fan location:

At this stage, you chose a location to install your fan. Do you have an existing bathroom fan? Then the task is simple. Just replace the old bathroom fan with the new purchased fan. The bath tub and the toilet are always perpendicular to each other. You are advised to install the fan in the center of both.



Drill a reference hole, mark out, and make measurement and cut:

Use the drill, make a hole at the ceiling, which will be the reference hole. Use a pencil to mark out the lines. You will make sure you mark knowing if there is electrical wire or other important structures located there.

Then, measure the vent housing, use the fan reference hole to confirm if it will fit the spot between two joists. Return to the bathroom measure the intake-port hole.

Put on the safety googles, as you use the dry wall saw to cut the marked lines. It is should in form of L shaped cut opposite the stud (if any) towards the vent damper.



Put the fan into the hole:

Simply and carefully fix the fan into the hole. Here you attach duct tape into L shaped or 90 degrees, of which you will attach the duct pipe. The fan contain in its housing a knockout or cover, remove this cover and attach a cable connector into the junction box.

Carefully lower the fan into the hole in the ceiling. And secure the fan to the joists.



Fix the outdoor vent and vent cap:

The vent is usually on the roof or exterior wall surface. Ensure not to vent damp air into an attic space, this would promote mold growth. To save expense you are advised to run vent to the shortest and straightest path.

For the vent cap attachment,

If you vent on roof: get to the roof top, draw a reciprocating mark and cut a hole. Install the cap and hold in place with roofing nails.

If you choose exterior wall venting: locate stud, take measurement from the inside to mark the same measurement outside. Cut through the wall and install the vent cap. You can apply silicone caulk with a caulking gun to seal properly.



Wire connection and Grille Installation:

Look around the bathroom to locate nearest light fixture, that you can connect power from to your Bathroom fan. You can choose to provide an extra switch so that the fan won’t have the same switch with the bathroom light. Reach for electrical outlet of the fan, twist the wire you pulled out to the wire from bathroom junction box. (Red to red, black to black). Tape the wire and push it back into the hole.

Good job! You are 99% done.

Install the grille into the spots which is provided in the fan housing unit.

Turn power on to experience your bathroom fan.
