Pulled out my insert today after 4 days running to do thorough cleaning but mainly to explore. Am running my outside air up through masonry chimney; it terminates inside the chimney (centrally located in house) and I have a screened intake at top of chimney. But I was surprised to see that the installer did not use the Harman OAK -- that is, he connected the outside air vent directly to the stub opening at the back of the unit, rather than use the kit that attaches to the insert frame.
On my invoice I paid for an "outside air vent" (the screen at the top) but not the Outside Air Kit. My bad for confusing them; I'm not saying I got "ripped off" but here's my concern:
If you reach into the stub, there's a flapper inside it. If I replace the outside vent into it and push the insert back into the fireplace, the flapper will be stuck open. Is that OK? That's how I've been running the stove the past 4 days since installation. It seems like I should use the kit to allow the stove to call for air when it needs it rather than have that flap open at all times. Should I call the installer back? As always thanks in advance for the great advice I receive on this forum
