Hi all, I have a Caddy wood furnace and I noticed that, during construction, a 2x4 was placed 1.5" above the hot air duct, in a place where the clearance requires 6" space. I consider placing a fire resistant material in between the duct and the 2x4, which will be much easier than removing the 2x4. Is this a good idea? If yes, what material can I use and where to buy it?
Thanks,
Beno
