does it come with damper for backdraft and bird mesh

Yes it does. The damper is light and is wide open on my low setting and shuts perfectly. The only thing which took some time for me to get used to is the sound of rain drops hitting it are pretty loud! Maybe because It is only about a foot from the intake to the top.

I think the vent through our roof has a backdraft preventer, not the heater itself. I have noticed no back draft at all.

Yes, it does. Even a stainless steel wing nut works too. I also found paper liners from another website that are just fabulous and help with the clean up.

Yes it does. They are not required to attach though. It includes covers for the gear doors in case you dont want landing gear.

Yes it does. It has an assist attachment under the deck that helps raising and lowering the deck.

No, it only comes with the back brace shown in the pictures. You will need to order adhesive pads separately.

Yes it does. I have an older version & it came with both, which you attach to the top after unpacking. It worked well to keep out the rain & allowed the cat to be able to look outside comfortably, if the flap is up.

Yes it does. Be careful when in stalling them because there is no predrilled holes to show you where to put them.

No. You will need to purchase 6" ducts and the hardware necessary to either go through your roof or soffit. It does come with a damper to prevent downdrafts.

This range hood has three knock-outs- a 3-1/4"x10" rectangular on the back, another 3-1/4"x10" rectangular on top, or a 7" round on top. It comes with the rectangular damper (to keep cold air from coming into the kitchen from outside), but does not come with a damper if you choose to connect via the 7" round pipe. You'll need something like this: http://www.amazon.com/Speedi-Products-AC-BD-07-Galvanized-Prevention/dp/B0085UZDXG/

Yes it has a back draft damper to stop any back drafting when not in use!!!!! If venting through roof I recommend using a Broan 636 fan-jack, it also has a damper to stop the cold air at the roof line so condensation won't take place. If venting through wall use the Broan 885 wall cap, it has a spring loaded damper and comes with a 4-3 reducer. Good Luck!!!!!!!!!!!!!MarkInnovative HYVAC Systems, Inc.

Hmm, I am not sure what a damper is. I can find out, but can you please clarify. Generally we are very happy with this item, but our atock isn't huge, but a nice size.

There is no damper on the unit. It is an open vent on the roof. It does have a mesh wire around the opening to keep out animals and debris.

No downdraft. I previously had a Thermador and a Jenn-Air, both with downdrafts. On each, the downdraft was useless and I stopped trying to use it. You really need an updraft hood. In addition, the Jenn-Air was incredibly junky and I was glad to see it go. The Bosch is terrific.

Yes it does, mine has been up for about a year now. Had to move it to protect my bird feeder from the raccoons.

Yes it does and even without them the bottoms onthe sides are mesh so the wind can blow through. I used this for a few days on the beach and didn't have any problems. If you're realy worried it also has tent pegs, but those aren't great for sand. We also had a small cooler that we had and moved it to the edge to stay out of the way and that might have helped, but we never noticed it doing anything.

It has Velcro attachments that connect over the crossbar. I purchased it more as a wind block but if it rained I believe the rain could get in from the gaps in the connections to the crossbar. Although this served my need I'm considering a model that comes with removable sides.
