Thanks. What are the national code requirements for hearth protection for use with a pedastal-style Coal Stoker Stove? That's the rub.
This design suggestion is what I'd like to do, but I have nothing to show the code official that this constitutes "Approved Floor Protection" for the LL Pioneer, which is what he wants. I had made this very design suggestion 3 weeks ago and he wouldn't approve it. This design may yield an R value of .70 or so, yet the after market UL listed hearth pads are R=1.44. So, are 2 layers enough or do I need 6?
I have to be able to define what "Approved Floor Protection" means, who "Approved it" and to what thermal conductivity standards (R or k-value). But most important is, does the manufacturer support it? Appreciate the code official's point of view: if there's a fire due to inadequate floor protection that he approved and the manufacturer didn't, he's on the hook. But if the stove manufacturer says it's ok (say, R-value of .50) then he's testing compliance to manufacturer's instructions and we all go home happy.
UL 1618 is the hearth specifications for stoves that comply with UL 1482. UL 1482 does not address hearth protection near as I can tell.
Thanks for your thoughts.
