Outside air intake questions

[Samandothers]

We plan for a stove in a walkout basement. This is a new construction so the house will be fairly tight 1800 sq ft. We have a PVC pipe from the area back behind the stove, outside the clearance envelop that will connect to the stove with flex metal. The PVC then runs in the ground under concrete pad and rises near the outside wall. We plan to place an air intake vent of some sort on the end of the PVC. The chimney will be close to 30' from the stove to the cap. When talking with the stove vendor it was suggested to add a stove pipe damper given chimney height and concern for amount of draft.

My question, Is there an outside vent cover for stoves that allows air intake but not back draft and helps to seal the intake from bugs and critters? Something like a dryer vent pipe in reverse?

Thanks for feedback

This is what is normally used. If you need smaller holes to stop insects, you could add a piece of screen to the item.

Thanks for the fast reply!

Do you by chance have the company or name of it that I may search to learn some detail?

Thank you for this.

I assume there is not a device that would allow air in toward stove but shut if air/ draft started back from stove to exterior? Like a back flow valve type device.

Haven't seen one, but there MUST be something like that out there, somewhere.
Maybe bholler will chime in... He does a LOT of installs.
