How to Install a Ventilation Fan

Ventilation followers are a reliable service to dampness concerns such as fogged home windows and balmy mirrors, according to basic professional Tom Silva ofThis Old House He demonstrates how to set up one in your restroom.

Head right into your attic room to find a suitable place for your air vent follower in between 2 ceiling joists and make use of a mounting square to note its consumption port opening.

Choose the Right Model

Ventilation followers offer a core feature: changing nasty or stagnant air with fresh, tidy air. Variations exist depending upon just how air flow followers relocate undesirable air out while drawing fresh air in, in addition to their resistance to air movement (fixed stress or SP) and appear created by them (sones).

Some air flow followers are little sufficient to fit conveniently right into an intermediary in a wall surface without requiring ductwork to be mounted, like those from iLiving which suit 13-inch-long intermediaries in residences, going up to 600 CFM with simply a solitary rate yet an optional remote makes rate changes feasible.

For complicated tasks, bigger commercial or industrial followers might be needed. They work as component of an air flow system by drawing away air movement far from stagnant areas with air ducts; typically located in animals real estate and greenhouse atmospheres where these electric-powered followers are constructed to stand up to harder atmospheres.

Whatever kind of air flow follower you acquire, guarantee it has actually been examined by a trusted lab to examine its efficiency under details problems. This will certainly make sure the producer’s cases stand which you obtain sufficient air movement. In enhancement, think about updating ductwork links to bigger dimensions as this can minimize fixed stress while at the same time allowing your follower to go for optimal power with lowered power usage.

Measure the Space

Before mounting your restroom air flow follower, it is essential that you determine the area where you intend to place it. This will certainly aid guarantee it fits pleasantly right into the space; most followers are ranked according to CFM or cubic feet per min ability based upon just how much air a follower can relocate each min; depending upon space dimension (e.g. a 100 square-foot restroom might need one with 100CFM ability). Use a measuring tape to properly determine elevation, deepness and size dimensions of ductwork prior to noting them onto ceiling with pencil and framework square.

Cut the Intake Port

Vent follower consumption ports should be appropriately sized to the air duct it links to. Based on the size and setup of your air duct run, speak with producer directions for finest techniques; or else inquire from an a/c professional regarding which dimension would certainly help your system.

Once you have actually identified the suitable air duct dimension, head upstairs to your attic room and find where the follower will certainly be mounted. Use a stud finder to find joists prior to choosing a location straight in between 2 joists as its area for real estate the follower – as soon as located mark it on the ceiling making use of pencil and design square or framework square for simple recommendation later on. In your restroom take dimensions for its consumption port prior to making use of design square to move those dimensions onto ceiling making use of design square after that eliminated with jigsaw.

Before setting up an air flow follower, make sure all breaker offering the location have actually been turned off, along with making sure not to harm any type of electric circuitry. As an additional step for security throughout sawing procedures use a respirator for included defense. When running an air duct pipeline with roof covering rain gutters think about including bare or eco-friendly copper steel basing cables (basing cables aid dissipate fixed electrical power); versatile air duct links must be sealed making use of aluminum foil tape sealer for included comfort.

Install the Fan

Ventilation followers can aid enhance interior air top quality by removing unclear home windows, balmy mirrors and fragrant air from shower rooms while getting rid of mold and mildew, condensation and mold accumulation which harms wallpaper and paint. Installing brand-new followers is generally a simple do it yourself job for home owners with some standard woodworking and electric expertise – nevertheless if your job entails rewiring or reducing ductwork to develop bigger air duct openings on roofing systems or collaborating with plumbing pipelines after that expert aid must be looked for from qualified electrical contractors.

Before starting work with any type of existing follower in your restroom, guarantee it has actually been turned off at your circuit box and unplugged making use of a voltage tester. Depending on its electrical wiring setup, expanding its opening by producing an L-shape cut towards its air vent damper might be needed; doing this while leaving in position the old follower guarantees its placing screws will certainly associate ceiling studs and joists flawlessly when making this cut.

Mount the brand-new follower to the ceiling according to producer directions for connecting its placing braces and attaching them safely to joists. If its follower box flange stays over or listed below ceiling drywall, caulk it for an impermeable seal (Photo 5). When installment is total, affix versatile ducting tube from follower to air flow air vent cap through versatile ducting pipeline (Photo 7).
