Hi I have a 1.5 year old QuadraFire Castille pellet stove insert and the rope door gasket is very badly frayed in 1 corner. I already had it replaced last year while it was under warranty. I don't think it's still under warranty so I have to replace it myself. I found this one on-line http://woodheatstoves.com/quadrafire-tadpole-door-gasket-factory-original-8425130-p-12293.html Is that the right one? Also, how do I actually replace it? It looks like the gasket is self-adhesive on 1 side, so it doesn't look too hard to install. Do I have to remove the glass from the door? Thanks a lot.
