Fitment Note:
The 842-5130 gasket may be used on additional Hearth & Home Technologies or Quadra-Fire appliances not listed above. Always verify the 842-5130 or 8425130 part number in your owner's manual, parts diagram, or service documentation before ordering.

Hearth & Home Technologies manufactures multiple brands and appliance families that use different gasket profiles. Do not determine compatibility by overall dimensions alone. Confirm the OEM part number whenever possible.

About the Tadpole Gasket Design:
Unlike conventional round rope gasket, a tadpole gasket combines a compressible bulb with a flat mounting tail. On the 842-5130 gasket, the approximately 1/2" bulb provides the compressible sealing section while the approximately 3/4" flat tail provides the mounting surface.

Together, the bulb and flat section create an approximately 1-1/4" overall gasket profile. Using the correct profile is important because conventional round rope or flat gasket tape may not provide the same mounting position, compression, or sealing characteristics as the original tadpole gasket.

Why Is the Door & Glass Gasket Important?
The gasket helps maintain the designed seal between compatible stove components. A worn, flattened, torn, loose, or deteriorated gasket can allow unwanted air leakage and may affect appliance operation and combustion performance.

Maintaining the correct gasket profile helps the door and glass assembly seal as designed by the appliance manufacturer.

When Should the 842-5130 Gasket Be Replaced?
Repeated heating, cooling, compression, and normal appliance use can eventually cause fiberglass gasket material to deteriorate. Inspect the gasket during routine maintenance and consider replacement if you notice:
• Flattened or excessively compressed areas
• Frayed or torn fiberglass
• Hardened or brittle gasket material
• Sections pulling away from the mounting surface
• Missing or damaged gasket material
• Visible deterioration around the door or glass assembly
• Loss of the original gasket profile

PSA Self-Adhesive Backing:
The approximately 3/4" flat portion of the gasket features a pressure-sensitive adhesive backing designed to help position the gasket during installation.

For best adhesion, the mounting surface should be free of old gasket material, adhesive residue, soot, ash, grease, dirt, and debris. Make sure the surface is clean and completely dry before applying the new gasket.

The PSA backing is primarily intended to assist with positioning. Follow the manufacturer's installation procedures regarding retainers, glass hardware, additional adhesive, or other securing methods required for your specific appliance.

Installation Tips:
• Allow the stove, insert, or fireplace to cool completely before beginning installation
• Carefully inspect the position and orientation of the original gasket before removing it
• Take photos during disassembly if needed for installation reference
• Remove the old gasket and any loose fiberglass material
• Clean away old adhesive, soot, ash, grease, dirt, and debris
• Make sure the mounting surface is clean and completely dry
• Compare the new 842-5130 gasket with the original before installation
• Test-fit the gasket before removing the PSA protective backing
• Confirm the proper orientation of the 1/2" bulb and 3/4" flat tail
• Remove the adhesive backing gradually while pressing the gasket evenly into position
• Do not stretch the gasket during installation
• Work gradually around curves and corners to maintain the proper profile
• Trim excess material only after confirming the final required length
• Follow your Quadra-Fire owner's manual or service documentation for model-specific procedures
