To put this to rest and verify the information I'm adding to this thread is accurate, I made a phone call.
I called Camco down in N.C. and spoke with Rob the engineer who oversees the Wave catalytic heaters. I asked him 3 questions. Is the catalytic reaction combustion? - Yes. If the main product of combustion, C02, builds up in the space and recirculates through the heater will it result in CO? - Yes. Do all the typical rules of combustion apply to catalytic heaters? - Yes.
The bottom line, which he made clear, a source of fresh air is absolutely mandatory for these things to be safe. He also said dirt or contamination can make these heater generate CO. This is the number for Camco if anyone wants to hear it for themselves: 1.800.334.2004
What rob told you is correct, there is a need for cross ventilation. It's in the instructions and on the heater. I have hold up in my rig for four days because of bad weather without any side effects. When use in the stove top for cooking the instructions say open a window a crack.
