To install a bathroom exhaust vent, drill a locator hole from the inside through the outside wall and cut a hole for the duct outside. For venting the fan out the roof, cut the hole from inside or drill a locator hole and cut the hole on the roof. Attach a short tailpiece onto the roof jack and install it.
To vent a bathroom fan through an exterior wall, cut a 3-inch or 4-inch hole with a hole saw drill bit. Access either the wall or the roof of the house as your point of intention to exhaust to the exterior. Bring your round vent (for walls) or vent cap (for roofs), reciprocating saw, cordless drill, pencil, and other tools.
An exhaust fan must have a clear pathway to the outdoors, typically supplied by a duct that passes through a side wall or through the roof. The fan is usually controlled by a wall switch and draws power from the fan housing. Carefully install the exhaust vent across the siding, sealing the gaps with exterior caulk.
Caulk the top and sides of the metal hood with a bird screen and back draft damper when installing it. Cut the hole for the vent using a hole saw (3″ or 4″ depending on the size of vent). Slide the wall cap into the duct hole and push it tight against the house siding. Cut a foam-rubber gasket to fit into any spaces where the wall is not properly sealed.

Building Code is minimal. BP- best practice or BAT- best available technology. Seems like you could have centered it half an inch down to get it even with the siding then. There are many better exhaust hoods, stainless, plastic less protruding, color matching, sprayed painted to color matching to the siding. Run rigid insulated pipe or again minimal insulated duct for moisture and mold. Stainless screws and color caulking anything but white. I do it right or don’t do it at all. End of story.
A lot of it is common sense. You should have seen the OLD exhaust fan I am replacing. The fan was installed in the 70’s. It had heat, light and vent and could run combination of these functions. It is only a 4 foot run on the first floor. Their is also a second floor above where the vent is. You did a great job on yours. Wish mine was that easy.
Vinny, Great job and good info along the way as you completed each step. Have you ever installed one of these on an house that doesn’t have a vinyl siding low enough to cut thru? If the house foundation has stucco… is there a way to cut thru that? My fear is running into the concrete foundation. Without the correct tools that could be a PITA to deal with just for an exhaust fan. Also, does the exhaust pipe have to run in a straight line to the outside or can it take turns?
