I suppose you could get air tight w/o removing the damper, but it would take lots more foil tape. If my damper hadn't been so easy to remove, I'd probably just done more taping. It is great w/o the damper. Plugs fit flush as does the fan. 4 pieces of tape and good to go. I'm just leaving my fan mounted since my pit area is covered and I also have a cover for wsm.
