I am very concerned that this oven was installed without a vent to the outside of the house. It produces enormous heat that becomes the chore of the air conditioner to remove adding to the energy consumption. Secondly if something should burn, the fumes will fill the entire house with nasty fumes. Thirdly any vaporized fats from food items will also enter the living space diminishing the air quality and coating all the contents of the interior in an ongoing basis. How can this design be approved by the GE product designers?
