The first time you fire up your stove, the lacquer will harden. This will produce smoke in the oven and give off a burnt odour, which will disappear when using strong ventilation. We therefore recommend that you open doors and windows to create a draught. The lacquer will be soften and become fragile during this hardening process, so do not touched the lacquered surfaces. We also recommend that you open and close the door every now and then during the first couple of hours of use, to prevent the sealing cord from sticking to the lacquer. This odour will disappear after the first couple of firings.
