Getting an Osburn Stratford II for a customer and they offer this fresh air intake control that gets mounted on the wall like a switch. What's the benefit of this if the fireplace has its own control? Was thinking maybe because you can close it off entirely in the off-season?

Could also do this manually, it's just one more thing to break over time. If installed, be sure to build in an access panel.
Ok yea was guessing it's just like an on/off sort of thing, they won't need that. I've been insulating my intake ducts lately to keep any cold infiltration out of my chase cavities. If a little bit of air runs thru the unit when not in use from the control on the unit not closing off entirely, that's fine. It's a sealed unit the air will just run out the flue.
I've seen folks add valves to the air intake to offer more control than the stove's air intake slider would offer. The EPA of course doesn't let you shut off the air to the stove with the normal stove control so this valve on the OAK, if that's the only air supply, could give the operator back control. Also nice if there was a chimney fire. I would want a valve that wasn't fully open or fully closed but allowed partial opening for use during a fire that is just too hot.
lots of ways but how about a regular hvac key damper? blast gate? think rv tank dump valve but metal
