Inside a top damper installation in Lake Davis/Greenwood

Details our Lake Davis/Greenwood team explains on every top damper visit.

Clamps, stops and removed plates

The same appliance manual says that if its clamp does not fit or cannot give the required opening, a permanent stop can be installed, the damper blade removed or the damper cut to leave the minimum opening.

Those options exist so a gas appliance always has its opening. They are the opposite of what a top-sealing damper is for, which is why we treat a fireplace with a decorative gas appliance as a separate conversation rather than a routine damper job. If you are unsure what is in the firebox, we identify it during the free inspection before anything else is discussed.

Rain when the damper is open

When the lid is open for a fire, the top of the flue is open too. One retailer's listing for the Lyemance damper notes that the damper itself gives no rain protection when open and offers a separate cap with a screen.

If you want protection while the damper is open, a model with a built-in cap or a matching cap is the answer. We explain the options that suit your flue and price them side by side. If rain during fires has never been an issue for you, a plain top damper may be all you need.

Cable length on taller chimneys

Top dampers are supplied with a long cable so they suit tall chimneys. One retailer's listing for the Lyemance damper, for example, lists a 32 foot stainless steel cable.

Before ordering, we measure the height from the flue top to the handle location, so the cable reaches the bracket with slack to set the clamp. On an unusually tall chimney, we confirm the supplied length is enough. The spare length is kept until the tension is set, then trimmed.

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.

Top damper questions from Lake Davis/Greenwood

Straight answers from our specialists in Lake Davis/Greenwood, with no sales pressure.

When can I close the damper after a fire?

Only once the ashes are completely cool. The Consumer Product Safety Commission advises keeping the damper open until then and never closing it at bedtime over warm ashes.

Will a top damper stop drafts from the fireplace?

It stops outside air moving down an idle flue when the lid is closed. It does not fix a fireplace that smokes during a fire, which has other causes that we can check separately.
