Years of Enjoyment Begin with Curing
Curing an oven removes potential residual moisture. Although your oven might seem dry once you complete the installation process, there are small moisture pockets that need to work their way out.
The initial fire must be started slowly. When lighting the first fire, keep the flames low so the moisture can be slowly released from the oven and the surrounding masonry. If you build a large fire in your oven from the onset, you could compromise your oven’s longevity and cooking efficiency—ultimately causing permanent damage which might void the manufacturer’s warranty.
This curing process should be conducted at a temperature as close to 212°F (100°C) as possible (do not exceed this temperature) for a period of six hours on three consecutive days. Exposing your new oven to this temperature over a few days will cause all the moisture to evaporate, allowing your oven to properly “cure.”
NOTE: Due to thermal expansion, small cracks might appear in the dome or hearth during the curing process. Don’t worry. This is normal and the quality of your oven will not be compromised.
ALTERNATIVES FOR CURING A WOOD-BURNING OVEN
Another method of curing your new oven is to build a fire in a separate location. Then, take the heated coals and place them in the oven. You’ll generate heat without a flame, and the oven will cure as required. Some new owners find this method much easier for curing the oven and ensuring that the temperature doesn’t get too hot.
CURING A HYBRID (WOOD- & GAS-BURNING) OVEN
The CBO-750 Hybrid Ovens (DIY Kit, Countertop and Stand models) use two burners for the curing process.
Set the Hearth Burner (bottom switch) to 250° degrees and run for four (4) hours with the door open.
After four hours, increase the Hearth Burner to 400° degrees. Then turn on the Ambient Burner (top switch) and run both burners for four (4) more hours with the door open.
After four hours, your oven is cured and you're ready to cook at higher temperatures. NEVER use a CBO-750 Hybrid oven with the door completely closed.
