Measurements of the oven mouth The size of the oven mouth is a personal choice and depends on the use of the oven. Is it only for baking bread and pies or do you also want to use it for making pizza and roasting meat? In the last case, the oven mouth has to be made wider and higher to be able to put in and take out of the oven, pizza’s and grills. Yet there are some general rules: The width of the oven mouth is always in proportion to the size of the oven floor so that the whole floor surface remains accessible. It is usually between 40 cm and 85 cm; The height of the oven mouth cannot be lower than 63 % of the maximum height of the vault. This is to ensure, during stoking, a better smoke duct and therefore a permanent air current, necessary for a good combustion. It is for that same reason that the oven vault’s façade is as high as the oven mouth. If this is not the case, then the smoke in the oven will start to precipitate and it will eventually extinguish the fire. The height of the...

Measurements of the substructure Size of the substructure Now that we know the size of the oven floor and the shape of the vault, we can calculate the measurements of the substructure: For the length we need the sum of: the thickness of the wall of the oven mouth (approx. 20 cm) + the length of the oven floor + the thickness of the vault ( approx. 20 cm) + the thickness of the insulation layer ( approx. 10 cm) + if necessary, the thickness of the outer wall ( approx. 20 cm), depending on if you close the rear side or not For the width we need the sum of: 2 x the thickness of the outer wall ( 2 x approx. 10-20 cm) + The width of the oven floor + 2 x the thickness of the vault ( 2 x approx. 20 cm) + 2 x the thickness of the insulation layer (2 x approx. 10 cm) + 2 x open space of minimally 1 cm between loam layer and outer wall Working height of the substructure The working height is equal to the height of the substructure plus the thickness of the oven floor. Usually it is between 80 cm...
