Compatible with medium size Winnerwell stoves with 2.5 inch chimney pipes, the Winnerwell 2.5 Pipe Oven allows you to bake tasty foods like biscuits, potatoes, and cookies in camp. The baking chamber measures 6 inch by 6 inch and is fully sealed allowing smoke to bypass the oven and escape out the chimney. An integrated thermometer and glass viewing window help you monitor temperature and keep an eye on baking foods.
