First there is a safety issue no vent. When burning propane or natural gas it puts off c02 . Second thing where is the gas connection or the propane bottle. This is one of those things I think one should stay away from.

GUYS!, Alcohol! Same as you cook with in sailboats which is about a confined space as you get. MUCH less CO than your furnace at home(ANY kind) puts out(up to 150 ppm allowed). I was nervous when I first built the house so tight about my 6 burner propane Russell Range(150,000 btu) so ran all 6 burners for 6 hours with a lab CO gauge sitting on the floor below it--Never budged off 0%. Did it again while furnace guy was here Monday and the highest reading was .5% in the mechanical room while he was dialing in the air mix--then 0% which is what my CO monitors always reads regardless of how many hours I've been cooking.
There, I've vented:)
That being said, when Dad swapped over to a gas range--his wife's cat did NOT change it's habit of snoozing on that end of the kitchen island. It moved it's tail in it's sleep and that nice bushy tail-You guessed it:) Dad says he didn't know who screeched louder- my step-mom or the cat! Spent the next 60 seconds trying to put out the cat and associated fires out with a spaghetti pot and a tea kettle:)
Cat didn't go near counter for the rest of it's life(so at least it cured that).

Actually, Some of them are kind of neat and I've always regretted not putting a fireplace or at least a flue for a woodstove in, but wheelchairs/woodstoves/snow is a bad combo for me.
First thought on some of these design was what a guy with a Diamond drag could do with glass:)

I used to put in unvented natural gas fireplaces all the time. They were all the rage. 100% efficient and put some humidity in the house. The fire log kind that set in old fireplaces.
I imagine they got enough venting because dampers don't seal all that tight, but personally, I didn't like them. The smell got to me.

I use a deck heater to warm the shop in winter, it's propane. Then I open the garage door and exchange the air, and then run a couple electric heaters. Otherwise I can't stand to be in there, and that deck heater is infrared.

Our gas fireplace is vented and has a switch on the wall. I love it. We use it constantly, it's a beautiful thing. That's what I need in the shop. :D

Oddly, those unvented wall hanging heaters that run on natural gas, they don't bother me a bit. I have a couple, I'm going to put them in the shop this winter if I can figure out a place to hang them. They used to be in my last shop, I just never had any need for one till now.
