Il forno di Faxius - un gioiello in acciaio con bruciatore

Hi , sorry for not talking italian . Im from Croatia and planning to build a pizza oven and also planning to use this pizza oven (faxius) from this post as a blueprint. I will though change the dimensions of the floor a bit because of the dimensions of my burner. I have attached photo of my burner It is 450 mm long and it is actually two burners connected together 2x8 kw. So total power is 16 kw. Dimensions of my floor will be 620 mm width x 500 mm long, and height of the ceiling from the stone will be 300 mm. I am planning to put one burner on each side (separate them , but each one will have its own control valve) of the oven (left and right side) . So far i havent find any oven with this kind of setup ( with two burners on each side) So I am wondering if you think that will be ok or I should pay special attention to something. Thanks a lot
Have nice day
