Why does my Superior Indoor Fireplace smoke an hour after lighting?
- AAntonio MccannAug 10, 2025
If smoking occurs an hour or two after lighting the Superior Indoor Fireplace, it might be because your well-insulated house is too airtight, preventing replacement air from entering to feed the fire. To resolve this, try opening a window slightly or opening doors to one or two rooms to see if the smoking stops. Also, check if your outside combustion air kit (if installed) is open and ensure there are no obstructions in front of the exterior air entry.
