Check that the damper is open. The damper is a device that controls the amount of air flowing through the flue. The flue is the passage or duct for smoke in a chimney. Feel inside the chimney or pop your head inside to look at the damper with a flashlight. There should be a lever which you can try moving one way or the other.
