What Type of Chimney Should I Install?
Find out which chimney type you need for your Alfa oven, including standard, pergola, and custom installations. 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.
