From outside, slide the wall cap into the duct hole and push it tight against the house siding. Remove the wall cap and apply a bead of silicone adhesive to the siding and gasket around the hole. We installed ultra silent Broan-NuTone vent fans in the bathrooms of the Kuppersmith Project house, to remove moisture from the air and prevent mold from forming after showering.
Mike’s trying to be sure he matches the right NuTone vent fan with the right bathroom, because each has a specific style and is designed to move a specific amount of air.

Bath vent fan installation, troubleshooting, repair: this article series explains why bathroom vent fans are needed and describes good bath vent fan choices, necessary fan capacity, and good bath vent fan and vent-duct installation details. We explain how to install bathroom exhaust fans or vents, the vent ducting, the vent termination at the wall, soffit or roof, vent fan wiring, bath vent duct insulation, bath vent lengths, clearances, routing, and we answer just about any other bathroom ventilation design or installation question you may have.
Ventilation in bathrooms is important to prevent moisture damage to wall and ceiling surfaces, decay of wood trim, saturation of building insulation, and mold contamination. Especially in bathrooms where a shower is used, large amounts of moisture are added to room air and are concentrated in this area. Our photo (above-left) shows a horrible bathroom ceiling vent fan ductwork job: multiple ducts sprawl around in the attic, all joining to terminate at an attempted through-roof vent that has fallen back into the attic. Flexible plastic vent fan ductwork: shown at above left is a common use of un insulated, flexible ventilation fan duct. Flexible metallic exhaust fan ductwork: shown at above right is flexible metal exhaust fan ductwork. Our photo at above left illustrates a solid metal bathroom exhaust duct along with the bath vent housing installed in a cathedral ceiling during new construction. Because this is a sloped cathedral ceiling it was not possible to slope the fan ductwork back down towards the shower below the fan. I'd have preferred using a fire-resistant foam, but if the above conditions are met you should be ok. Flex duct routing details: If you are using flexible fan duct, stretch the flexduct tight to keep it as straight and smooth inside as possible.
Do not spill bath vent air into the building attic or roof cavity where it will condense on and damage building insulation, roof sheathing, possibly framing, and where it will certainly encourage mold growth.
Isn't there a danger of wet bathroom exhaust air re-entering the attic through the soffit vents if the fan is exhausted through the soffit? Our article BATHROOM VENTILATION cites the importance of venting bath vent fans to the outdoors, not into an attic or crawl space. The question about moist air reentering an attic through soffit vents after it has been blown out of an exhaust vent opening is a fair one, but I don't think that's likely to be a significant building moisture source. Or speaking from empirical experience, having inspected several thousand homes and having looked very carefully at moisture and mold stains and patterns in attics and under roofs, I've not found any instances of back-venting of problem moisture into the attic through the soffit vents near the bath exhaust vent that presumably is blowing out through the same soffit or a nearby building vertical wall. Bath exhaust fan duct length specifications and restrictions are discussed separately at BATHROOM VENT DUCT LENGTHS. Reader Question: is it OK to vent a bath vent fan straight-up, vertically out through the roof?
I am going to install a new bath fan, I am having a new roof put on the house and decided now would be a good time to put the vent on the roof. My question is I got a vent for 6" ducting, I will need a reducer at the fan end to 4" Would this be a good size duct for the fan.?
You've raised several key topics, and your question helps us realize where we need to work on making our text more clear or more complete. For example on site I might notice something about your attic and roof structure, ease of routing venting, placement of insulation, and even very basic stuff like - where the heck is your home?
I prefer to run a bath vent to outdoors via a horizontal line that goes across an attic and out through a gable-end wall or one that vents down and outside through a roof overhang or soffit.
The vertical run guarantees that any condensation runs back down into the fan (risking damaging the wiring or fan motor) and back into the bath or bath ceiling.


The vent fan manufacturers installation instructions typically give maximum run lengths and recommended vent diameters for their products; long vent runs and vents that use plastic dryer-type flex-duct (not your case) cut the effectiveness of the fan by adding airflow resistance and thus increase the risk of accumulated moisture too. I am guessing that for a very short bath vent duct run, going to a larger duct size is fine - it'd make no difference but you're probably not gaining a thing on a short run by using a 6-inch duct to vent a fan that expects to vent through a 4-inch duct. In my experience inspecting and troubleshooting buildings, I've seen many bath vent fans that seemed ineffective. The fan capacity you need depends on the size of the bathroom being vented - usually calculated in cubic feet. Sorry that these notes are a bit long on arm-waving and short on more specific details, but as we've got no information about your particular installation except what's in your original note, I have to stop here. Bathroom vent fan duct length restrictions: keep the fan duct length as short and straight as possible. Some manufacturers require a minimum distance between the duct outdoor termination and the fan assembly; a review of installation guides for several bathroom vent fan models did not come up with a maximum distance. Details about maximum and minimum bath fan duct run distances or lengths are at BATHROOM VENT DUCT LENGTHS. Typically the bathroom vent fan is powered by the bathroom ceiling light fixture circuit; some installers, particularly in hotels or rental units, hard-wire the bath exhaust vent fan to force it on when the bathroom ceiling light is on - thus assuring that the vent fan is in fact used.

I have come across your site 3 times, as I continue to get our recently purchased 1950's home up to snuff. Are there any restrictions on how close an exhausting bath vent may be placed to an exhausting vent for a gas water heater? You will see that the required distances range from 1 foot to 7 feet depending on what's being cleared-from. My builder has installed a small 4" extractor fan in a newly created utility room with a door to outside, but no windows. Mary I'm not sure I've got the whole picture, but I'd agree that a metal or plastic duct liner would have made cleaning easier and would have reduced the chances of damage should moisture accumulate in or condense on the sides of the air path. Question: Can I vent a bathroom into the attic space that has soffit vents and a ridge vent? Well air flow may carry moisture but enroute, flowing across attic surfaces it will also deposit it on cooler surfaces - leading to mold-sorrows later. We get a sewer smell in two of our four bathrooms in the fall when it turns cold and also in the spring. You might also be facing odors exacerbated by partly clogged drains or defective vent piping.
Anon the best answer is site specific - depending on framing and construction details such as which way ceiling joists run I might go into the ceiling and then out through the wall, or I might place a vent right into the exterior wall.
Your installers needed to adequately seal or baffle around ceiling vents, ducts, HVAC air intakes, etc. There is a more serious worry here if your bath vent is for a ceiling exhaust fan: loose fill insulation that enters a power-operated bath vent can clog it leading to overheating and a fire. We moved into a house built in 1999 in north Florida and learned that the bath exhaust fans are connected to the HVAC ductwork and not to the outside. I can't be as smart as an on-site expert who will see important details we can't, but what you describe sounds wierd to me.
Why is the air from my bathroom exhaust fan blowing down into the bathroom instead of blowing up and out? If your fan is ONLY an exhaust fan then it's running backwards OR there is no exhaust vent.

I searched around to try and find something else that would work but was unsuccessful so I decided that I needed to make something myself.
Cut a foam-rubber gasket to fit into any spaces where the wall cap doesn't contact the siding. Now I guess the sizing of these things is real, real important because of course, this is a very small bathroom right in here but a lot of people just undersize those things, don’t they?
You know, you want to make sure that you get the proper size unit, so that it will pull the steam and the moisture out of your bathroom.
I mean I know people don’t want to have another hole in their roof but why would you want to put everything right up in your attic?

In this installation the duct is improperly installed, spilling directly into the attic space of the building. This material is more smooth-surfaced than the plastic product shown at above left and by its flexibility, can eliminate the need to install many elbows in the system. Solid ductwork has a smoother interior surface that improves airflow, though it is indeed more trouble and a bit more cost to install.
The ceiling cavity between the I-Joists was later insulated with solid foam, as shown at above right.
I sprayed insulation foam ( not the fire block ) around the bathroom vent fan in an attempt to seal small air leak from the attic . Take a look at the bathroom vent fan duct installation in the photographs above and you'll see a succesful bath vent installation in a foam-insulated cathedral ceiling. Once blown at any velocity into outdoor air, the moist bath vent exhaust air is diluted significantly. Is it ok to vent the bath vent fan through a larger duct size than the fan's outlet diameter?
A competent onsite inspection by an expert usually finds additional clues that would permit a more accurate, complete, and authoritative answer than we can give by email alone.
Bath ventilation worries may be a bit different in a cold climate than in a warm dry one and different again in a wet humid climate.
I prefer to minimize the number of roof penetrations on any building since every penetration is a potential leak point, more so if the penetration flashing is not installed correctly. Metal duct work (your case) is in my opinion always a better installation: smooth interior means better airflow.
A fan that nobody uses because it's too noisy means a bathroom that is rarely vented adequately (risking mold, smells, even wet insulation).
That figure is matched against the fan manufacturer's recommendations for fan capacity measured in cubic feet per minute (CFM). Our photo (left) illustrates damage we found in a building ceiling where the exhaust vent duct had been torn during installation. The electrician wants to finish the job quickly and get paid and go home for a beer and to watch the World Cup on TV. The building inspector doesn't want to crawl into a hot attic, and furthermore, cannot possibly inspect every detail of every job - so over time the inspectors tend to get to know individual contractors and to trust (or not trust) their work, making just spot checks on it. I am following up on this with the buildings inspection office and getting everything rerouted properly.

The text is intended as a reference guide to help building owners operate and maintain their home effectively. This duct material is least costly at the time of installation but may be most costly when a combination of accumulated condensation and duct damage leaks into the building insulation or ceiling cavity. The CFM rating of the fan in turn presumes that the vent routing, diameter, length, and number of obstructing turns and bends is within the company's specifications. I have two concerns; first when I have this running for one bathroom i don't want it sucking all the heat out of my house (in winter) from the other 3 bathrooms. Or should I try to go around the upstairs rooms to get to the gable attic, and to a vent there? The second just seems like a long distance, but I can't find much info about venting out the side of the house.
