I used my Coleman cat heater last week. I also had a professional type,
small CO(carbon monoxide) detector. Even so, I chickened out and turned it
off after a half hour--- Went to bed late and had to get up early; did not
want to risk the detector's alarm going off if it hit 35ppm CO and being
woke up at 4 am.
In morning, turned on heater for 1 hour and then checked detector, was at 33
ppm.
