I have a pretty cheap turkey fryer burner that I got from Bass Pro a few years back. I brew in my garage with the door open and sometime setup a fan to circulate air. The two times I've brewed I noticed that there was some high levels of carbon monoxide (it prompted it to move the burner more towards the opening and it fixed the problem). One thing is the burner was not "burning blue". I managed to do a test last week and got a full blue flame, will doing this decrease the CO hazard in the future?
