It's not weird at all. I am in the industry and have sold or installed.....I can't even think about how many, non-vented gas logs, heaters, etc. They work very well and are extremely safe.
My home (when I lived in the GA mountains) was heated upstairs by a set of non-vented logs, and downstairs by a 20K non-vented heater.
