As one of the posters said above, there are vents in the top of the oven which i assume vent gasses up into the trailer (which then should get vented outside by the hood fan). To tell you the truth, this is the first time i've been living in the trailer with cold weather where we haven't had a ton of windows open while cooking. The carbon monoxoide detector going off is one up high on the ceiling but also is on the far end of the TT in the bedroom (rear kitchen, front living). The floor one in the kitchen that is hardwired is not going off.
