How does it install? Does it use existing screws, does it bolt in to the 14 by 14 vent, will I need to put new screws into the roof?

It all comes with the vent only thing you need is silicone to seal the new screws very easy to install took less then ten mins to install two vents

If you have good bite with the screws, they will pull the mounts down to the roof. I put a nice dab of silicone in the pre-drilled hole before installing the screw.

My installation was for a 14 foot ceiling. The chimney extends upward. I vented to an outside wall so it worked fine for that application. It depends on whether you intend to vent upward through the ceiling - mounting height is a factor. I believe the chimney extends to a grand total of three feet. If you plan to go upward through the ceiling, Amazon does sell a chimney extension kit: http://www.amazon.com/ZLKBWEXT-1-Piece-Extension-Model-Range/dp/B00E4Q0FF6/ref=pd_sim_la_2

It has new studs. You need to retain and use the old lug nuts. No new mounting bolts.

none, you attach it to the screws already there. If there are no screws or existing brackets you need to install the new brackets using an eigth inch drill bit and re-caulk very well.

Hi Dan,The main thing to look at when replacing your vent lid is the hinge style which can be found as one of the pictures on the product page. These will fit all 14" x 14" vents. Since it seems you are just replacing the lid on an existing vent then you should have no trouble making this work as long as the hinges match up.

All you will need to do is install the rack system. No modifications needed to the roof to install.

This is an UPGRADE kit for an existing fan. However, the fan does fit in a standard 14x14 hole. But if you do not already have a "Fantastic Vent", this won't work for you. You need model 6600R/417, which is the WHOLE thing.

If you already have a vent to the outside or you will have to do it yourself.Comes with... but may have to buy the clamps to fit

I'm not sure but I can tell you this. Remove the interior piece of the current vent and measure the opening. If it is 14"x14" it will fit . I'm very happy with this product and highly recommend it to anyone! Hope this helped you. �

Yep, should fit right up. Get a friend to help and position it under your roof, mark the mounting holes and drill em. Mount and wire, and you're rocking!!

Sorry for the delay in answering. It attaches to your existing vent cover. Very easy installation. Requires drilling of four holes to attach the mounts. Then you attach the Maxxair Vent cover to the mounts. It took me approximately 15 minutes. Your existing cover can be raised and left open during rain and while you are traveling. However, your cover will only open 3/4 of the way, which still gives you plenty of ventilation. The quality of the plastic cover is quite good.

Mine came with two parts that attached together, as well as a small instruction sheet showing how put together. It sounds like you're maybe missing the part to fit in vent, at which point you should contact seller, since you can't get missing piece separately.

Both. You remove 4 screws holding your vent down to the roof and screw the mounting L hardware in those holes using the same screws along with Maxair bolts supplied. Then attach the Maxair which is larger than your vent and covers it.

We converted standard hex head bolts to match the special twist in bolts by grinding two sides of a conventional bolt head and getting them to fit into the slot or channel. Won't you still need the framing to make a roof panel into a hinged vent panel? Good luck.
