Exhaust Fan Setup Instructions

If your bathroom just cannot seem to dry out, a simple option is to install a fan. Eliminating humidity and unpleasant smells from the restroom improves the experience for everyone using it.

The most physically demanding parts of bathroom Exhaust Fan Installation are climbing a ladder, working at a high level, and crawling about in a tight space in the attic while wearing a dust mask or respirator. Aside from the labour involved, installing a bathroom vent fan requires just a single 120V power supply and a stretch of flexible ducting no more than 6 feet long.

How To Put In An Exhaust Fan In These Simple Steps

Figure Out the Number and Placement of Fans

How big an exhaust fan you need for your bathroom or kitchen is determined by how big those rooms are? You can choose the best fan for your space by taking measurements and researching independently. The fan's mounting placement is another consideration.

Locate or Determine the Source of the Power

The Ductable AC for the toilet will be mounted above. You may already have electricity going to the location where you will install the bathroom exhaust fan. You may expect your bathroom ceiling light to get electricity from the lighting circuit. You may also use a fan/light combo instead of the standard lamp.

If installing a ceiling fan in a bathroom needs a separate circuit, a new wire may be routed from the electrical panel to the ceiling. If you are not confident in dealing with the service panel and setting up additional circuits, it is time to call an electrician.

Fan - Velcro It On

The next step is to screw the fan enclosure to the joist. Connect a 4-inch 90-degree duct elbow to the side output port of the vent fan housing after you have returned to the attic. Put some foil duct tape on the dock and straighten the elbow.

Connect a wire there where the fan casing has a knockout. The four metal brackets must be inserted into the notches on each side of the exhaust fan. Place the exhaust fan between the joists, centred above the ceiling access hole.

Put the Ventilation Fan Outside the Bathroom

Connect the flexible ducting to the fan and the vent after you know where to put the fan. Make sure the piping operates as efficiently as feasible. Installing an exhaust fan in the bathroom and kitchen helps prevent mould growth and germs.

Make a Hole for the Ventilation Fan Inside the Wall

Using the stud finder, mark the ceiling joists gently with a pencil from below. Without a suitable template, the metal fan housing may be used (the fan assembly can be set aside for the time being). The joist is a standard mounting point for bathroom exhaust fans. If so, the cut lines should be made with the template or housing placed perpendicular to a post.

Put the Ventilation Fan Outside the Bathroom

Get back inside the lavatory and double-check that the fan is installed vertically. Collect your aluminium foil tape and flexible ducting and return to the attic. Attach the flexible piping to the exhaust fan and the vent using foil tape. (Instead of using foil tape, you may find that your lover or ducting comes with mechanical fasteners for fastening the duct.) Keep the tube as straight and as smooth as possible.
