The inch's of the fan relates to the size of the incoming and outgoing ducting. So for this 8 inch unit. Its an 8 inch duct. All ducting is made to have a small amount of flexibility in the gap between connectors of the same size. This gap is usually closed with aluminum tape, or Duct Tape. Also depending of the temperature of the air being ducted. A layer of insulations might be used. Some ducting systems come with ducting and insulation in one.

8" ductwork is needed with these fans. Mounting brackets are included. They also come with one 8" adjustable clamp that can be found at any hardware store or home depot if you want another one. I would definately get some silver foil duct tape to make everything have a nice seal as well as 3" screws to hold the fan in place.

the problem with this grate is that there is a flange on the back which may impede your ability to fit this over a duct. My best advice is to write the manufacturer or buy this from someplace you can return it easily

You can install this easily on your own. No need to spend on a service charge from the furnace company. Just make sure you are getting the right size. The best way is to look at the one that is already in the ductwork entrance/exit to the furnace and make sure that you use the same measurements on the filter already in place.

Whichever size you get will have the matching collar pre-attached. Very easy to attach your duct with self tapping sheet metal screws.

It has a 4 inch round duct. The pic doesn't do it justice; it's beautiful. I was easy to install, works extremely well and is very quiet. It was a great purchase!

Yes, it's quite possible. No need for ducts, but make sure you have the carbon filters. If the filters are not installed, all the exhaust will filter into your walls/ceilings which is not good. Installation is pretty easy, but you also need 2 people because it's heavy. Also, if you can use toggle bolts to secure the vent to the ceiling, much more secure than the items they give you. It's a nice looking vent, I would for sure recommend.

Yes you can install it on either side of your ductwork. I have mine installed exactly opposite of the photo shown for the unit here. While you purchase it, you might as well buy a spare filter for inside, it uses one per season in my area, probably due to hard water. I also hooked my water feed up to the hot water line in my house so that it can work at it's optimum.

No, you will be required to run and connect the electrical wiring and duct from above. Also, it is much easier to install the unit with joist brackets or direct joist attachment (for close joists) when working from above. This unit uses a 4" duct, whereas most existing duct is 3-1/2"...if this is a replacement. Most states, by code, require that an exhaust fan must be installed with a duct to the outside of the home. The unit can be covered with standard attic insulation, as it generates virtually no heat (no light).

the duct opening (hole in the floor) on mine is 12 X 2.5 "I had some concerns when I ordered becasue the description of the product is poor, but they fit perfectly and are a great value. Cheaper than buying them t my hardware store by a few bucks even when you add in the shipping. Unless you have an odd-sized opening, which I highly doubt, I would order them. Nice product.

If you want to get technical, you will want to know the CFM (cubic feet per minute) of the fan you are using. If you have a 6 inch and a 4 inch fan with the same CFM, they will vent the same amount of air. You will need 6 inch ducting to attach to the hood, but that does not necessarily mean you can only use a 6 inch fan. I rigged this up to a lasko blower fan from walmart (~$45) and it does well.

This unit is rated at .8 sones. The sone rating remains the same whether you use a 3" or a 4" duct.

Jimmy, I am using 4" duct (actually sewer pipe) through out my shop) and it is proving very effective) with gates to limit the collector to one machine at a time. I can't say that it won't work, but it will not be as effective since the airflow is limited by the 4" connection. Not worth the $.

no you will need to purchase the 6 inch duct and roof vent. This unit is very good and super quite. you can hardly hear the exhaust fan and the heater does a very good job of heating the bathroom

You would need to run a exhaust duct think it is four inch. It doesn't need to be insulated.

Yes, it comes with a small 5"+ section of duct plus the outside grill. If you need more than the 5" you will need to buy additional duct.

Yes, I believe so provided the dimensions fit. Although it does not require outside ductwork, it does need to be vented into attic or have a return air vent. It's worked extremely well for our needs. I had read that if you do heavy stovetop cooking, such as wok-type, a different system would be better. The only other thing I can think of is that your soffit might be too high for effectiveness. Ours is 32" above stovetop. They had a model set-up at Lowes that might help you decide.
