Why does the fire go out or smolder when I close the door or the bypass damper?

This can occur due to several factors:

  • The fire was not burning hot enough to produce the draft needed to pull the air into the fireplace. Feed more dry wood kindling before closing down the stove.
  • The chimney draft is weak due to too many restrictions; chimney height below the minimum; draft is diluted due to poor gasket connection(s); loose clean out door.
  • The wood is not properly seasoned or too big to create the heat necessary to produce draft.
  • Air shutter was not open enough. Open the air shutter all the way to get the fire burning briskly before shutting it down.
