Doesn't matter whether you're burning wood or propane, carbon monoxide is produced. You have to be careful with any unvented fuel burning equipment inside an enclosed space, even the ones that the manufacturers say are okay for use in tents and shanties.
The vented heaters, like Nu-Way's propane and wood fired heaters, are less likely to produce elevated levels of CO in a blind. Venting the heater would be difficult in most cloth blinds but is easy to do in a permanent wooden blind.
I use one of the Coleman "Cat" heaters in my cloth blind and I keep a window open and my head above the opening. My wife has a vented Nu-Way LP heater in her wooden blind. Neither heater seems to bother the deer.
