Blaze king princess insert UL 127 OR ULC S620 requirement

[greythorn3]

I was wondering what these UL 127 OR ULC S620 mean, i cant find anything on my majestic fireplace insert... i was wanting to put a blaze king princess insert in it someday but am not sure if this is possable due to the UL 127 OR ULC S620, and not knowing what it means or if my fireplace has that requirement.

Nothing in my manual when I did the install. BTW this insert rocks. I have been working on dialing it in.
