Q: Jason, the cable that leads up to my Lymance chimney top damper seems to be puncturing my Chimney Balloon. I attached an image of the damper to show you where the cable is. -TP
A: TP- I see the cable as a very faint line just to the left of the Chimney Balloon valve in the picture. I see the cable runs along the edge of your metal damper there as well. What is happening is this cable is getting frayed over time as it rubs up and down against the metal edge of this damper opening. That frayed section of cable has little needle like protrusions and a flat side that is like a saw blade in roughness. I also notice that the Chimney Balloon is tight like a drum when installed. It is probably a little two tightly inflated.
Two things will help solve your issue here…
Remove your Chimney Balloon and wrap packaging tape around your chimney top damper cable in the area the Chimney Balloon will come in contact with it. This will keep the flat sharp end of this cable from cutting the balloon.
When you reinstall and inflate your Chimney Balloon do not fill it so tightly full with air. You can leave a little give in it. – Jason
