Freestanding wood stove, fresh air supplied. Block when not used?

[joea]

I have a free standing wood stove that I added fresh air intake to. I found that helpful to the overall experience.

However, I now find it desirable to block the outside supply in the off season. I suppose I should have thought of that before, but, oh well.

Looking for a reliable and cost effective way to seal that off by inserting something in the 4" duct path on the house interior. Did some searching but most stuff seems to be a bit bulky, cumbersome, expensive. WAY overkill.

Seems something as simple as a "sliding gate" that could sit up against or close to the exterior wall would fit the bill. But, so far, not finding anything.

Surely this is a common need. ?

Aha, it looks like a 4 inch "blast gate" comes close to what I envisioned.

A ball of aluminum foil...?

Just put a note in the stove to take it out before lighting it... Lighting will go fine (door open) but once you close the door you'll smother it....

That requires I disconnect the inlet duct each time, or at least seasonally.

This is what I'm going to try:

^^^This was getting grouchy that my fist fire of the season wasn’t taking of. Then after the third time I closed the door and snuffed it out I remembered the tape!

Adding the not this year.

Not if you insert it on the outside termination of the duct?

There is a fixed in place insect/critter grill/screen installed there.

Only 4 screws, but in any case, "blast gate" has a very appealing sound to it. Not going to examine that too deeply.

I got an email notice that someone asked what this is, but cannot find the message.

This is called a "blast gate" and is intended for dust collection systems, mostly woodworking I think, to allow closing off lines to machines not in use.

There are many variations. This particular one is at:

Thanks. T'was me. Deleted my message after I figured it out. But the link is helpful. Just ordered one.

Another benefit of adding this is to close it during an event like a chimney fire or runaway stove. It wil function as a key damper in the chimney to some extent depending on how much combustion air actually comes from this supply pipe.

Some stoves get 100% of their air from the oak, and some only a portion.
