Questions about this item

How do I install the 1-1/2" polyethylene conical plug in a fireplace opening?

Press the tapered plug firmly into the 1-1/2 inch opening until the conical sides grip the surrounding material; the step most people miss is checking that the plug sits flush so drafts cannot bypass the seal.

Will the polyethylene plug degrade and need replacement after repeated heating cycles?

Polyethylene softens with sustained heat, so plan to inspect the plug each season and replace it once the material shows permanent deformation or surface cracking.

At what temperature does the plug start to lose its seal during continuous fireplace use?

The material begins to soften well below typical flue temperatures, so the seal is the first limit reached — expect loss of grip once the surrounding area exceeds moderate warmth.
