I would keep a window or vent cracked even though the heater I plan on putting in it will supposedly shut off when the Oxygen level gets to 18%. I was also considering installing a small vent near the heater. I was just wondering because I hope to use it as an ice fishing house too. The temperatures could get in the negative range.
