At some point I'll have to go to bed and get up in a few hours for work, but until I get tired I'm hanging' in the camper. I need to run the heat tonight as it will flirt with freezing, so I have it plugged in and the furnace set at around 60.
Questions about the furnace, a Suburban model. Do I need to crack open a window and vent to allow for air flow, or is the burner/heat exchanger harmful gases (CO) isolated from the interior? Cracking a window for tonight and sleeping in the house, but would really like to know. The Suburban instructions do not have the usual warnings of death by CO poisoning. Been there, done that except for the death part -- yields one heck of a headache.
