For Alfa gas ovens, the ideal flame should be predominantly **blue with some yellow tips**. This indicates efficient and optimal combustion.   --- ### **📌 Characteristics of the Ideal Flame:** ✔ **Blue color with yellow tips** → Indicates proper combustion with a good balance of oxygen and gas. ✔ **Stable and well-defined flame** → Should not be too high or too low and should not "flicker" excessively. ✔ **No excessive soot or gas odor** → A flame producing too much smoke or a strong gas smell suggests inefficient combustion.   --- ### **🔧 What Can Affect Flame Color?** 📍 **Power setting** → At maximum power, the flame may appear more intense, while at minimum, it might look weaker and less defined. 📍 **Gas quality** → Impure gas or incorrect pressure can turn the flame yellow-orange and generate soot. 📍 **Air ventilation** → Poor airflow in the installation area can alter combustion and change the flame’s color. 📍 **Dirty burner** → Residues, impurities, or spider webs inside the burner can cause a yellow or irregular flame.   --- ### **⚠️ Common Issues and Solutions** | **Flame Color** | **Possible Cause** | **Solution** | | --- | --- | --- | | Entirely yellow/orange | Incomplete combustion, excess gas, or insufficient oxygen | Check ventilation and clean the burner | | Too weak and short | Gas pressure too low | Verify pressure regulator and gas level | | Flame extinguishes easily | Strong drafts, clogged burner, or potential gas leak | Protect the oven from wind, clean the burner, and check for leaks | | Flame with excessive black smoke | Impure gas or incorrect air setting | Check gas quality, clean the burner, and adjust air settings for proper combustion | --- ### **🔎 Inspection & Maintenance** ✔ If the **flame color is incorrect or unstable**, turn off the oven and check if the burner is clean. ✔ If the **problem persists**, check the gas pressure and ensure the regulator is compatible with your oven. ✔ For **precise adjustments**, contact a specialized technician or your nearest Alfa dealer. 🔗 **For technical support, refer to the user manual or contact customer service.** 🔗 **Find an authorized dealer for gas assistance: Dealer Locator** -
