Cooled air leaving through the fireplace

An air-conditioned room loses cooled air through an open flue, because the warmer air in the chimney keeps drawing on the room below it. A damper left open, or one that no longer closes, turns the fireplace into a vent that runs between fires.

A cast throat damper closes metal against metal, so even a good one lets a little air past. A warped or rusted one lets much more. We check the seal with a light from below and tell you whether a new plate will close the gap or a gasketed top seal makes more sense. Feeling a draft near your fireplace in Lake Shore?

Dampers seized from disuse in Lake Shore

Away from the coast, one of the hardest things on a damper is simply sitting unused. Pivots rust in place over idle months and the plate stops moving.

Opening and closing the damper by hand a few times a season keeps a sound damper in your Lake Shore fireplace working.

Where the code puts a throat damper

The Florida residential code wants the damper in a masonry fireplace to be iron or steel, mounted 8 inches or more above where the opening ends, and worked from inside the room (R1001.7.1). That height keeps the plate clear of the opening itself, above the flames rather than among them.

When we replace a whole damper, the new frame goes back at or above that height, and the control is placed where it can be reached from the room without leaning into the firebox. A replacement plate in an existing frame inherits the frame's position, so the height is measured and written down either way.

Why a half-open damper chokes the fire

Section R1001.6 of the residential code asks that the passage above the firebox, throat and damper included, be no smaller than the flue it feeds. A damper plate that stops partway cuts that passage down, and smoke that cannot get through the throat fast enough rolls out of the opening instead.

That is why our damper checks measure travel rather than just asking whether the plate moves. We open it by hand, note where it stops, and look for the cause: a bent stop, a warped edge catching the masonry, a crank out of thread or debris behind the plate. The repair is finished when the plate reaches its full open position.

The clamp that keeps a damper open

A vented decorative gas appliance set into a wood-burning firebox is listed under ANSI Z21.60, and its installation instructions require the damper to stay open to a minimum area whenever the appliance is installed. A metal clamp or stop fastened to the damper does that job.

That clamp stays in place while the appliance is installed, even when a customer asks for a damper that closes. If the fireplace is going back to wood, the appliance comes out first, and then the clamp can be taken off and the damper tested through its full travel. The estimate records which of those two situations applies.

Damper questions from Lake Shore homeowners

Do you repair fireplace dampers in Lake Shore?

Yes. Our crew frees, rehangs and replaces throat dampers across Duval County, Lake Shore included. Describe what the handle does when you call, and the right parts come along to the free inspection.

Will a new plate do, or does the whole damper go?

A new plate is enough when the frame is flat, uncracked and has sound pivot lugs, and a matching plate is still made. If the frame has failed, the whole damper is replaced or a top seal is fitted instead.
