Fitment Note:
Regency manufactures many different gas fireplaces, inserts, and heating appliances that use different glass gasket sizes and profiles. Always verify 846-700 or 936-273 in your owner's manual, parts diagram, or service documentation before ordering.

If replacing an unidentified gasket, carefully compare the profile and measurements of your existing gasket with the approximately 1/2" bulb, 1-1/8" flat fiberglass section, 1-5/8" overall width, and 1" PSA backing listed here.

Do not assume that another Regency gasket will interchange simply because it has a similar appearance. The gasket profile, compression, width, mounting method, and installation orientation should match the requirements of your specific fireplace or insert.

About the 6AL Tadpole Gasket Design:
Unlike conventional round rope gasket or flat fiberglass tape, a tadpole gasket combines a compressible sealing bulb with a flat mounting tail. This specialized design provides both a compressible sealing surface and a convenient mounting area.

On this gasket, the approximately 1/2" graphite fiberglass bulb provides the primary compressible sealing section while the approximately 1-1/8" flat fiberglass section provides the mounting surface. Together, the complete gasket profile measures approximately 1-5/8" overall.

The flat section also features approximately 1" wide PSA self-adhesive backing to help hold the gasket in its proper position during installation.

Why Is the Fireplace Glass Gasket Important?
The glass gasket provides a protective and compressible sealing surface between the fireplace glass and surrounding components. The correct gasket helps maintain the glass in its intended position while reducing direct contact between the ceramic glass and metal components.

Using the proper gasket profile is especially important because an incorrectly sized gasket may provide too much or too little compression around the glass assembly.

When Should the Glass Tadpole Gasket Be Replaced?
Repeated heating, cooling, compression, and normal fireplace use can eventually cause fiberglass gasket material to deteriorate. Replacement should be considered if you notice:
• Flattened or excessively compressed gasket material
• Frayed or torn fiberglass
• Hardened or brittle sections
• Missing gasket material
• Sections separating from the glass or mounting surface
• Damaged or deteriorated adhesive backing
• Visible gaps around the glass assembly
• Loss of the original tadpole gasket profile

It is also a good idea to carefully inspect the gasket whenever the fireplace glass is removed for cleaning, service, or replacement.

PSA Self-Adhesive Backing:
The flat fiberglass mounting section features approximately 1" wide pressure-sensitive adhesive backing. The PSA helps hold the gasket in position during installation and makes it easier to maintain proper alignment around the glass.

For best adhesion, remove old gasket material, adhesive residue, soot, dust, grease, and debris before installing the replacement gasket. The installation surface should be clean and completely dry.

The PSA backing is primarily intended to assist with positioning the gasket. Always reinstall the glass, retainers, and related components according to the procedures specified for your Regency appliance.

Installation Tips:
• Turn off the gas and electrical supply before servicing the fireplace
• Allow the appliance and glass 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 glass assembly according to the manufacturer's instructions
• Carefully remove the existing gasket and loose fiberglass material
• Remove old adhesive, soot, dust, grease, and debris from the mounting area
• Make sure the glass and mounting surfaces are clean and completely dry
• Compare the replacement gasket profile with the original gasket before installation
• Test-fit the gasket before removing the PSA protective backing
• Confirm the proper orientation of the bulb and flat mounting section
• Remove the adhesive backing gradually while positioning the gasket evenly
• Avoid stretching the fiberglass gasket during installation
• Work gradually around corners and curves to maintain the proper gasket profile
• Trim excess gasket only after confirming the required finished length
• Reinstall the glass and retaining hardware according to the manufacturer's instructions
• Do not overtighten glass retainers or mounting hardware

Important Gas Fireplace Safety Note:
Proper glass and gasket installation is particularly important on gas-burning appliances. Always follow the installation and service procedures specified for your particular Regency fireplace or insert.

Do not modify the original glass gasket configuration, block designed air passages, or substitute a substantially different gasket profile. If you are unsure about the proper gasket installation or condition of the glass assembly, have the appliance inspected or serviced by a qualified gas appliance technician.
