chimney draft
Smoke's upward pull
Chimney draft is the flow of air through a chimney, created by the difference in temperature between inside and outside air.
Hot air rises and draws combustion gases up and out while pulling fresh air into the fire below.
A good draft keeps smoke moving upward; a poor draft causes smoke to spill into the room.
