I measured the hole, so it would be the bottom dimensions. Some fit snugly, and some were loose because the floor coverings were not cut uniformly.

Bottom side, in other words it is the approximate size of the floor opening

They recommend about a 6" clearance in the back for ventilation. The sides, I do not believe, have any clearance specifications. You may want to check their tech specs on their website for side clearances, just for confirmation.

Measure the outside dimensions (length, width & height from roof to top of vent in the open position) in inches to make sure the Maxxair will properly fit over the vent cover while it is in the open position. NOTE: my vent covers will only open to about 80-85% of their height before contacting the inside of the Maxxair, whick is OK for me.

You're trying to get the volume of air coming out, so it's best to measure the duct. The installed grill will reduce flow so if you want to know exactly what's happening, measure the inside of the grill opening edge to edge, not from the outside lip. Some grills that are adjustable restrict the flow quite a bit, so depending on what you are trying to figure out, take that into account too.

I can't really tell anymore because it's install and you can't see. If I had to guess, I would say about 2 or 3 inches. It is a great vent though.

There are different sizes of floor vents and different sizes of Air Flor Breeze. Go back to their website and read further. On my 104 year old house, I had to modify my vent size opening.

Get a heavy duty one and measure the area between the outside wall and inside wall make sure you get one thats adjustable to that width.

At the top to the lever that opens the vent it is just shy of 2" and just the top portion is 1 inch. The bottom to wall is 2 1/2".

The vent extender is smaller than 14" but ours is 14 inches also. I used a little duct tape on the sides and it worked fine. Hiding under a China hutch so you don't see this until the hutch is moved for cleaning.

I bought mine for a ceiling vent and I measured and compared to the dimensions listed on the item page. I would guess that my home has standard size vents and this worked perfectly for us, but I would measure just to be safe.

I would look closely at the many reviews that warn of missing side vents. It is highly likely that the piece will be defective. At that point it doesn't matter what tray it fits on. Buyer beware!

yes. You will have about 1/4" so measure carefully! The vent stack was particularly hard to install. Might consider getting a couple of stainless self tapping screws. It is easy to put together on the ground but the vents would stay together at the joint. (There is a groove that the top one fits into the lower vent stack but it get popping out of mine!) Looks nice, works, fine and I got a great deal on it! Directions are horrible - translated from Chinese to English by a non-English speaker for sure!

you measure the floor opening. I don't recommend buying, if you will be stepping on it. The plastic inside that adjusts the air flow broke on mine, and now the top part comes lose all the time.

The vents are on the top & bottom of the unit behind the facing surround. Carlos

You will need the extra extensions. You also might want to consider going from both ends of the vent.

Due to curving of surfaces, it is hard to get exact measurements, but I tried my best:Inner diameter: bottom 8 1/4" , top 10 3/8"Outer diameter: bottom 9" , top 11 1/8"Bottom heating surface diameter 7 3/4"
