Top dampers fitted properly in Bryn Mawr
Practical notes from the damper installers serving Bryn Mawr.
Where the Florida code places a fireplace damper
Section R1001.7.1 of the Florida Building Code, Residential, gives a masonry fireplace a ferrous metal damper 8 inches or more above the top of its opening, set in the fireplace or in the chimney that vents it, and worked from the room the fireplace is in.
Sitting in the chimney and worked from the room by its cable, a top damper matches the arrangement that section describes. We check the product's own documentation for the rest, and we never describe an installation as bringing the whole fireplace up to code. Questions about a particular product's listing go to that product's paperwork, which we read before recommending it.
Keep it open until the ashes are cool
The Consumer Product Safety Commission advises keeping the damper open until the ashes are cool, because an open damper prevents poisonous gases building up inside the home.
Because a top damper makes the flue so easy to close, this rule matters all the more. Leave the handle released until the ashes are fully cold, then pull it down and lock it at the bracket. If you are unsure whether the ashes are cold, leave the lid open until morning.
A lid that will not open
If the handle is released and the lid stays shut, do not light the fireplace. The cause can be a seized hinge, a broken spring, debris or a cable caught on the way down.
Our crew checks the damper from both ends and frees or repairs what is stuck. If the unit cannot be made reliable, we quote a replacement and explain whether any other part of the flue top needs attention. The cause is written up, so you know whether it was a one-off or a sign of wear.
Testing the damper before we leave
Once the adhesive is in place and the cable is set, we work the damper through its full travel several times, from locked closed to fully open.
From the roof, the closed lid is checked for an even seal, and we confirm the lid rises fully when released. The adhesive still needs its full cure time before the first fire, and we tell you exactly when that is. Any adjustment needed after that first test is made on the spot.

Answers about top-sealing dampers for Bryn Mawr homeowners
Questions that come up on damper visits in Bryn Mawr, answered plainly.
Does a top damper replace my chimney cap?
It can, when the damper has a built-in cap and screen. Other models work alongside a separate cap. We tell you in writing what happens to your current cap.
Does a top damper need maintenance?
Very little. A yearly check of the gasket, cable, spring and bracket keeps it reliable, and the clamp may need re-setting if the cable stretches. We can do that during a yearly chimney inspection.
