Dampers serve to control the draft out of a fireplace and into the flue. Generally speaking, they must be wide open when burning anything. But that’s a double-edged sword. We want them open to let the smoke out and not fill up the room. On the other hand, we need them closed when the fireplace isn’t in use to prevent heat loss. Additionally, any fireplace with a gas appliance installed must never be closed completely when the gas flames are on.
Inspecting the dampers must be a “hands and knees” affair. Get down, use your flashlight, and carefully look up. Report missing or damaged/displaced dampers.
The damper is inoperative. This prevents proper function, and can be a safety hazard. Repair or replace the damper.
The damper is missing, which permits conditioned air to escape up the flue. This is an energy loss issue. Replace the damper.
The damper door is not seated properly. This prevents proper function. Repair or replace the door.
The damper is obstructed and will not open or close properly. Remove the obstruction or replace the door.
The damper door handle is missing. This is needed to open and close the damper. Replace the door handle.
