Smoke smell around the fireplace surround, soot staining on the masonry, or visible fraying where the liner meets the insert box are all signs this gasket has worn out. The Enviro Flue Collar Gasket (part 50-1413) replaces the worn flue collar seal in compatible Enviro wood insert systems.

Purpose

This gasket seals the joint between the wood insert box and the stainless liner, keeping smoke and combustion gases from escaping into the masonry cavity behind the appliance.

Key Benefits

• Direct-fit replacement for the factory Enviro flue collar seal — no modification needed
• Restores an airtight connection between insert and liner
• Made from a high heat-resistant material suited to flue collar temperatures
• Inexpensive way to address a part that is often damaged during liner cleaning or install

Specifications

• Approximate dimensions: 7 1/4 ft. o.d. x 5 3/4 ft. i.d. x 1/4 ft. thick
• Enviro part number 50-1413 (also listed as 501413)

Other Notes

Check this gasket whenever the liner is removed for cleaning, since it commonly tears or compresses during that process. A gasket that has lost its seal can allow combustion gases to migrate into the home, so replace it at the first sign of damage.

While you have the insert open, it is worth inspecting the door rope gasket and any related seals for the same wear pattern, since they age at a similar rate.
