Are ventless gas stoves safe to use in my home?

Ventless gas stoves are designed to burn fuel cleanly and safely, and they include built-in safety features like oxygen depletion sensors (ODS) that automatically shut the unit off if oxygen levels drop too low. When installed correctly and used in accordance with manufacturer guidelines, they can be a safe and efficient heating solution. However, because they use indoor air for combustion and release byproducts into the living space, proper room ventilation and adherence to local building codes are essential—some regions restrict or prohibit their use altogether.
