Top damper installation, step by step, for Kingswood Manor homes
The points below shape the damper we recommend in Kingswood Manor, and each one appears in your estimate.
Why a decorative gas appliance rules out a sealing lid
Vented decorative gas appliances are made for solid-fuel fireplaces with a working flue. The manual for one such appliance, tested to ANSI Z21.60, requires a damper clamp permanently installed to keep a minimum opening and prevent full closure, with the damper fully open whenever it burns.
Any lid that seals the flue shut works against that requirement. If your firebox has a decorative gas appliance, we read its manual first and tell you plainly when a top-sealing damper is the wrong choice for that fireplace. Where you want to keep the gas appliance, we explain what can be done about drafts and rain within its instructions.
Fastening the bracket to the firebrick
The bracket usually needs two small holes in the firebrick. In the Lock-Top sheet, the first anchor goes in, the bracket is checked for straightness, and the second hole is drilled through the bracket as a guide.
We drill with a masonry bit sized to the anchors and keep the holes neat. A straight, firmly fixed bracket matters, because the clamp on the cable bears against it every time the lid is pulled shut. The holes are small and sit toward the front, where they are easy to reach and do not weaken the firebox lining.
Setting the clamp for a tight seal
The seal depends on how firmly the lid is pulled down. In the Lock-Top instructions, the adjustment clamp is slid up the cable to the bracket, the cable is pulled to close the damper, and the clamp is set for the tightest seal.
We set the tension, then check the closed lid from the roof to confirm it sits evenly on its gasket. Too little tension leaves gaps, while too much strains the parts, so the setting is checked rather than guessed. The clamp setting is noted, so a later adjustment starts from a known point.
Smoke chamber and firebox work stay separate
Installing a top damper often gives a good view of the throat, the smoke shelf and the firebox walls. Sometimes those areas need work of their own, such as cracked firebrick or a rough smoke chamber.
Anything we find there is shown to you and written up as a separate item with its own price. The damper job stays the damper job unless you decide to add more. You can add that work to the same visit or leave it for later, and the damper job stands on its own.

Answers about top-sealing dampers for Kingswood Manor homeowners
Questions that come up on damper visits in Kingswood Manor, answered plainly.
Does the old throat damper have to come out?
Not always. It can be left fully open, fixed open or removed, as long as it cannot close on the cable. We explain the plan for your plate before any work starts.
Can you install it if animals are in the chimney now?
Not until the flue is clear. Animal removal is handled first as its own service, and the damper goes on once the flue is confirmed empty.
