Mason-Lite 36 Inch Virginiana Vented Gas Burner with Logs for 49 Inch Firebox Kits

Yes, an internally mounted damper, known as a throat damper, can be installed just above the firebox opening. These are typically operated by a poker-style handle, an internal lever, or a rotary key located at the fireplace, offering easier operation than a pull-chain damper. For example, the Vestal 36 Inch Cast Iron Throat-Style Fireplace Damper comes as a complete assembly, and the Vestal Poker-Style Fireplace Damper Control is available separately. However, we cannot confirm if a throat damper will work in your specific fireplace without an on-site inspection. Installing one in a finished brick fireplace requires altering the masonry of the smoke chamber above the firebox. Additionally, standard throat dampers are designed for single-sided fireboxes, and your see-through fireplace has a different configuration. A CSIA-certified chimney sweep or NFI-certified technician needs to measure your fireplace's throat to determine compatibility. You can find local professionals at CSIA and NFICertified. It's important to note that if your see-through fireplace uses a vented gas log set or burner, the chimney must maintain a permanent free opening at all times. The Virginiana vented gas burner, like the one on this page, includes a damper clamp to ensure the damper cannot be fully closed, and it must remain fully open while the burner is in use, as detailed in the Virginiana vented gas burner manual. Any new damper installation would need to accommodate this requirement, so confirm this with your technician. Before considering a new damper, you might explore easier operation of your current Lyemance top sealing damper. The difficulty could stem from the cable, its routing, or the hardware. Replacement parts like the Lyemance 40 Foot Cable, Lyemance 50 Foot Cable, Lyemance Damper Extra Hardware Pack, and Lyemance 4 Foot Stainless Steel Cable Shield are available and may help. The Cable Shield can ease operation if the cable is rubbing. For a comparison of throat dampers and top mount dampers, please refer to our Fireplace Dampers and Chimney Dampers Buyers Guide. All available dampers can be found on the Fireplace Dampers and Chimney Dampers page. A discontinued product that attached a lever with a removable handle to a mounting bracket might be replicable by a local welder.
