my dad has an outdoor boiler and we just replaced the rope gasket and used the tube of glue that came with it for the install. We used a wire wheel to clean the channel before gluing. The bottom of the gasket came loose after 2 days of burning. I think it is the creosote that glues the gasket to the boiler and that rips the gasket loose. He will only burn wet wood because "dry wood burns too hot". What do all of you use to put the rope in the door? Someone else said to use high temp rtv silicone.
