Which Olympia Chimney Models This Applies To

Olympia Chimney manufactures throat dampers and top-sealing dampers across several product lines, and the part you need depends on when your fireplace was built and how the flue was originally configured. The cast-iron throat dampers common in Toms River homes from the 1970s through the early 2000s are typically 30-inch or 36-inch models with a 3/16-inch thick plate and a left-hand pivot pin. Newer top-sealing dampers, like the Olympia Chimney Lyemance-style units, use a stainless cable and spring assembly that seals against a silicone rubber gasket at the flue top.

To identify yours, look for the stamped model number on the damper frame, visible from the firebox with a flashlight. If the plate is rusted smooth, measure the frame opening width and the pin-to-pin depth. We carry both OEM Olympia Chimney parts and quality aftermarket equivalents from Gelco and Famco. The aftermarket route saves roughly $60-$90 on parts without sacrificing fit, though we always recommend OEM if your fireplace is still under its original builder warranty. One compatibility gotcha: the Olympia Chimney 36-inch throat damper used a 5/8-inch pivot pin through 1998, then switched to 1/2-inch. Mixing the pin sizes cracks the frame casting.

Signs Your Olympia Chimney Damper Is Failing

• Cold downdraft even when “closed.” The damper plate has warped or the frame has rusted out along the seat, letting outside air pour down. In Toms River, we see this worsen after nor’easters when the pressure differential across the roof is strongest.
• Smoke spills into the room on startup. The plate is stuck partially open, or the pivot pin has seized with creosote buildup. The flue can’t establish proper draft until the fire is hot, and by then your living room has taken the hit.
• Rust flakes or grit in the firebox. The cast iron is actively corroding. Once pitting reaches 1/8-inch depth, the plate will never seat cleanly again. Salt air from the barrier island accelerates this in Toms River homes within a few miles of the water.
• The handle turns but nothing moves. The linkage between the handle and the plate has broken, or the plate has dropped off its pin entirely. This is common in older assemblies where the cotter pin has corroded through.
• Visible daylight or rain coming down the flue. The plate is missing, cracked, or fully detached. Rainwater mixing with creosote forms acidic compounds that eat the smoke shelf. We’ve rebuilt smoke shelves in Silverton and North Dover after exactly this scenario.

Replacement Cost & What’s Included

What drives the range: accessibility of the damper frame through the firebox opening, whether the smoke shelf needs repair from water damage, and if the flue tile above the damper has cracked from thermal shock. We quote upfront after a Level-2 camera inspection. The number on the estimate is the number on the invoice. Photos you can see, a plain-English verdict. Nothing is recommended without camera evidence you can see for yourself.

DIY or Call Us?

There is a safe middle ground here. You can verify the handle operation, shine a flashlight up to spot obvious rust or missing pieces, and check for debris blocking the track. What you should not do: attempt to remove a seized cast-iron plate with leverage tools. The frame is brittle, the pin is under spring tension, and a slipped wrench can crack the firebox throat or send rust fragments into your eyes. We’ve been called to Toms River homes where a well-meaning owner broke the frame trying to force the plate free, turning a $340 repair into a $1,200 throat rebuild.

The flue doesn’t lie. Neither do we. If your damper is stuck, rusted, or missing, call (609) 303-9679. We’ll match the part to your Olympia Chimney model and quote it honestly before any work starts.
