The co2 you might be making is not helping if the room is ventilated. And I am glad it is or you would have a dead cat. Here is another post someone replied in the advanced forum to your statements of having 600ppm co2 normally.
600ppm is about right if he lives on a traffic median. You'd think he'd be happy with the 30% increase over ambient of 400ppm...
You should get him a carbon monoxide monitor for Christmas. Sounds like you know your shit but if he won't listen to you perhaps he'll listen to a high-pitched beeping noise.

I am not disputing what you say about yellow flame, etc. I'm sure there is CO being produced, but I have been doing this for a while now with no problems. Perhaps the fact that the door to the room is always open is something I should have mentioned. So, the room is well ventilated. And, along with the CO it is producing beneficial CO2.
As for the dangers, what about a kerosene lantern? That's a yellow flame. Gas lighting was fairly common a long time ago also.
I think we've exhausted the topic. It is working for me, they way I am currently doing it. Thank you for highlighting the necessity of keeping the room ventilated.
