Liner through damper

[Ctwoodtick]

Was wondering if any issues can occur when a flex liner is making contact with edge of damper area while stove is operating normally. I don't mean if the liner is smashed against it but just up against it. Would the constant expanding and contracting of liner eventually damage the liner if up against edge of damper? While my liner is insulated, the insulation begins just above that spot in liner.

If it is rubbing against the damper I would take an angle grinder and cut the damper back a bit in that area.

I just thought of how my installer used a fire retardant insulation in damper area. If I was able to stick a bit of that insulation behind liner in that area, would that suffice?not sure how much give the liner would have for me to do that.

Ok, I thought you were in the process of self-installing. You'll have to judge the flex. Is this kaowool (white) insulation?

The insulation is like an off white color, in that ballpark and listed on quote as " fire retardant" by Installer. If left as is, do you think the liner (heavy wall) would be fine anyway?
