Top sealing damper installation in Virginia Gardens, explained
A damper that closes the flue at the top
A top sealing damper is a hinged lid mounted on the top of the flue. A gasket around its edge presses against the frame when it is shut. A cable runs from the lid down through the flue to a handle inside the fireplace, so you open and close it from the room.
Because it closes the flue at the top rather than just above the firebox, the whole flue sits behind the seal when it is shut. Rain, leaves and animals stay out, and so does outside air. When the lid is open, the flue works as it did before.
Inserts and liners have their own top
If a wood insert or stove vents through a liner in your chimney, the liner and its termination follow that appliance's manual. The top of the liner is part of that system, not a spare surface for a damper.
Tell us if anything like that is connected to the flue. We look at the appliance and liner instructions before discussing any damper. The appliance manual governs the flue in those setups, so we follow it rather than adding parts it does not mention.
Confirming the closed lid from above
Once the cable and handle are set, someone goes back up to look at the lid in its closed position. The gasket should be pressed evenly all the way round, with no gap at the corners or the hinge side.
That step is in the maker's instructions for a reason. A damper that looks closed from the firebox can still leave a gap at the top. We check it with the handle locked, adjust if needed and check again. The record of the work notes that the seal was confirmed from above.
Open the lid before lighting a fire
The rule for any damper is simple: open it before the fire is lit. With a top damper, release the handle and let the spring lift the lid. The handle position should show clearly that it is open.
One maker's instructions add a warning not to start a fire if the damper is not clearly open. We repeat that at handover. If the handle does not move as it should, or the position looks wrong, leave the fireplace unlit and ask us to check the damper first.

Answers about top dampers in Virginia Gardens
How do I open the lid before lighting a fire?
Release the handle from its bracket so the spring lifts the lid. Most designs show a clear open position at the handle. If you cannot tell that the lid is open, do not light the fire, and ask us to check it.
What if the cable breaks with the lid closed?
Do not light a fire until the damper can be confirmed fully open and the fault is repaired. A spring-loaded lid may open when cable tension is lost, while a stuck or damaged mechanism may not. We check the model and condition before recommending replacement parts.
What if my chimney has more than one flue?
The damper goes only on the flue that serves the fireplace. Other flues keep the termination their own appliances call for. We identify each flue before recommending a damper or cap for any of them.
