Follow these key installation tips. The **installation of the chimney** for your **Alfa oven** depends on where you place the oven. Below are the **most common configurations** and **guidelines** for a correct installation.   --- ### **1️⃣ Standard Installation (Without Overhead Covers)** If the oven is **installed outdoors** with **no overhead structures**, the **single-wall stainless steel chimney** provided with the oven is **sufficient** to ensure proper smoke evacuation. 📌 **Standard Chimney Characteristics:** ✔ **Material:** **Single-wall stainless steel.** ✔ **Recommended Height:** **1 meter.** ✔ **Customization:** The chimney can be **extended** to improve **drafting** or to adapt to the surrounding environment.   --- ### **2️⃣ Installation Under a Pergola or Roofed Area** If the oven is placed under a **pergola, roof, or any overhead structure**, the **chimney must extend beyond the top of the structure** to ensure **proper smoke venting**. 📌 **Key Rules for This Installation:** 🔹 **Replacing the Chimney:** ❌ The **single-wall chimney** that comes with the oven **CANNOT** pass through ceilings or roofs. ✅ A **certified double-wall insulated chimney** **MUST** be used to ensure **safety and thermal insulation**. 🔹 **Extending the Chimney:** ✔ The **chimney must extend at least 1 meter above the highest structure** it passes through. ✔ If the **extension exceeds 1 meter**, it is recommended to install a **butterfly damper** to **regulate airflow and drafting**. 🔹 **Minimum Safety Distances:** ✅ At least **100 cm** of free space under a **non-combustible ceiling**. ✅ At least **8 cm of clearance** between the **double-wall chimney** and any nearby **structures**. 🔹 **Recommended Materials:** ✔ Use only **chimney pipes and components** from **specialized manufacturers** that comply with **local building regulations**.   --- ### **3️⃣ Custom Installations (Using Bends or Deviations)** If your installation **requires bends or deviations**, follow these **guidelines** to avoid **drafting issues**. 📌 **Guidelines for Using Bends and Deviations:** ✔ **Maximum of two 30° bends** to maintain smooth airflow. ❌ **Avoid** using bends greater than **30°**, as they may **block the airflow**. 📌 **Minimum Chimney Requirements:** ✔ The chimney must **extend at least 100 cm** above the highest point where it exits the roof. ✔ The chimney must be **at least 50 cm higher** than any part of the building within a **3-meter radius**.   --- ### **4️⃣ Regulations & Professional Consultation** ✅ **Check local building codes** to ensure compliance with **safety regulations**. ✅ If unsure, **consult a professional chimney specialist** to design and install the venting system **safely**. 📌 **Need Additional Support?** 🔗 [**Contact Alfa Customer Support**](https://www.alfaforni.com/en/contact-us/) By following these guidelines, you can ensure a **safe and efficient** chimney installation for your **Alfa oven**!
