The Oven is a staple for every house in Project Zomboid. It is used to cook Pots of Soup.When the pot is in the oven you have to turn it on. If you leave an oven turned on for too long it will start a fire in your house. Fires early on in the game are crushing and can easily kill you. Whatever you do DO NOT leave the oven on unattended. If you are leaving a safehouse an oven is the best way to burn your house down as it requires less materials than a molotov cocktail. Burning down a safehouse kills zombies as you move.
Currently you cannot take out a fire at the moment.
Beware if you burn a food item, the oven may catch on fire even if turned off after your item is burnt.
