Inside a top sealing damper job in Elder Springs

Sizing the damper to the flue

Top dampers are made for specific flue sizes. The Lyemance range listed by Rockford Chimney Supply runs from 8 by 8 inch to 17 by 17 inch flues, with rectangular and round versions including a 12 inch round, and each frame is meant to sit on a flue of its own size.

The flue opening on your Elder Springs chimney is measured before ordering, including how far the tile stands above the crown. A damper chosen by guesswork can overhang the tile or leave gaps that the adhesive has to bridge, so the size goes on the estimate only after it has been measured.

Adjusting the cable for a tight seal

Once the bracket is fixed, the handle, chain and cable are threaded through it until the slack is out. The Lock-Top instructions then have the installer pull the cable to close the damper, set the adjustment clamp for the tightest seal, tighten it and cut off the excess cable.

That final adjustment decides whether the lid truly closes. Our installers close and open the damper on your Elder Springs chimney several times after adjusting, check the lid from the roof and leave the handle set so that locking it in the bracket means the damper is shut.

Servicing an existing top damper

Top dampers have parts that wear. Gaskets harden or tear, cables fray or stretch, springs weaken, and a lid can bend in a storm or when someone forces the handle. The damper may then leave a gap, refuse to open fully or stay shut.

Our team inspects the existing top damper on your Elder Springs chimney from the roof and from the firebox. We tell you whether a part replacement is possible for that model or whether a new damper makes more sense, and we price the option you choose before any work starts.

Chimney cleaning with a top damper in place

A top damper sits right where a sweep's brush comes out of the flue, and the cable hangs down the inside of it. Anyone who cleans the chimney needs to know the damper is there, open it fully and work around the cable instead of through it.

When we clean or inspect a chimney with a top damper in Elder Springs, our team works with the mechanism in mind. After your installation, the written record names the damper, so any future service visit starts with that information.
