Help me understand

Hi all.

It’s been a while since I posted here. I hope all is well and everyone is warm.

The ESW manual for the 28-4000 says: “When selecting the required floor protection it is important that you install a U.L. Approved board.”
I’m not so sure I am understanding this completely. It doesn’t say anything of R value or thickness or anything else at all, however, at the bottom of the paragraph it says: (Canada: place on a non-combustible Type 1 ULC spark and ember floor protector...

Isn’t that basically anything non-combustible?

I would appreciate any insight into this.

Thanks

Yes, that is ember protection. If this is on a concrete floor, nothing needed.

What if it’s on hardwood floors?

What exactly is a UL approved Board?

Prefabricated hearth?

the reason I posted this in the stove and fire place section is because the 28-4000 is essentially a NC30 within a cabinet, bigger ash pan and better blower.

Also more people frequent fireplaces and stoves.

What exactly is a UL approved Board?

It means the got UL certification for use in this application.

I guess I’ll just wait until I talk with the installer. Don’t know it has to be so vague.

The question is what is a "UL approved board" as required by the instructions. The instructions do not say "ember protection only" and if the OP wants to maintain his insurance he needs to meet the manual's requirements. The NC30 has a large R requirement for the hearth, as I recall it is 1.5.
