Tips for adding IntelliFire Plus remote control? (Heat & Glo)

I have an IntelliFire Plus Pro RC100 remote control for my Heat & Glo fireplace. Does anyone have any pointers to how I can get it to work?

PDF documentation for the remote is here:

It is a nice marketing sheet,
But nothing about signaling or protocols.
Does it use infra red?

Sorry for the late reply. But no information on the protocols. But I think it’s radio for sure. No ir or anything like that.
