No one in my area ever heard of boiler putty. After doing a search, I assume there is a difference between furnace cement and boiler putty. I want to build a DF520, if I can't find the boiler putty, what else can I use that is just as good?

Thanks

We had a long discussion when I was putting my 520 together. You can buy boiler putty from your EFM dealer, some of us used high temp silicone and I went with plumber's putty. The area where you are sealing does not get that hot.

I have used Permatex Ultra-Copper silicon in high heat applications. It rates at 600 degress continous and 700 degress intermitant. That is hotter than I have needed. Also it stayes on.

Found some SOS Putti about two hours away. Had a co-worker who lived close to the supply house pick me up a 5lb tub. He said even the guy who sold it to him wanted to know what it was used for.
