Just remember to leave the chimney cap on while your Uuni 3 is not in use. We would also advise storing your stone baking board indoors when not in use, as moisture can affect the way that it cooks. To keep your Uuni 3 in top condition, store indoors during harsh weather like wind, snow or heavy rain.
Uuni 3 by Ooni performs well all year long, rain or shine... even at Ooni HQ in 'sunny' Scotland. We have successfully used Ooni ovens in temperatures as low as -22˚C (-8ºF).
