The Casa2G Series ovens feature a fully sealing oven door jam and metal door, which are essential for proper oven operation. The oven door jam and door are capable of completely cutting off the air supply and the vent from the oven cooking chamber, allowing the homeowner to control the size of the fire and if needed, completely extinguish the fire -- which are necessary for controlling oven temperature, enable the oven to retain heat, and at times are needed for fire safety.
The Casa2G oven door includes a dial thermometer.
Take care not to build or purchase an oven where the vent is inside the oven chamber, behind the oven door. With this faulty design, the oven will continue to breath in air through the chimney and vent even after the oven door is closed.
