How to Install a Kitchen Chimney at the Right Height and Position for Maximum Efficiency

Key Takeaways

Installing your kitchen chimney correctly ensures lasting performance and a smoke-free environment. Keep these key points in mind:

• Maintain 24–30 inches height from the gas stove; closer for high-flame Indian cooking (around 26–28 inches).
  
• Choose the right duct size: 6 inches for 60 cm chimneys, 8 inches for larger ones, and use rigid pipes for smooth airflow.
  
• Keep ducts short and straight, and seal joints to prevent leaks.
  
• Centre the chimney directly above the hob and maintain clearance from walls or cabinets.
  
• Pick the right kitchen chimney size using Glen’s 60cm vs. 90cm Chimney Guide.
  
• For compact kitchens, consider efficient models like the Glen Designer Push-Button Ductless Chimney (60 cm).
  
• If you live in a rental or need portability, the Glen Electric Portable Chimney with Oil Collecting Cup is a great no-drill solution.
  

If your kitchen still feels smoky even after switching on the chimney, chances are it’s not installed at the right height or position. For Indian homes, where cooking often involves frying, tempering, and spices, proper chimney installation makes all the difference between a fresh kitchen and one coated with oil film.

In this guide, we’ll explain the correct chimney dimensions, how to select the ideal kitchen chimney size, the right duct setup, and smart placement for the best smoke extraction. These insights are drawn from Glen’s expert installation resources and real-world experience in designing appliances for Indian kitchens.

What height should I install my kitchen chimney from the gas stove

The standard height for a kitchen chimney is 24 to 30 inches above the gas stove. This range ensures effective suction without overheating the hood. If you cook with strong flame or heavy oil, a height of 26–28 inches offers better smoke capture.

Different chimney types also affect this distance. Straight-line and vertical-glass chimneys usually sit lower, while island and designer chimneys can be slightly higher because of their wider suction area.

If you’re still unsure about which chimney width fits your cooktop, Glen’s practical comparison 60cm vs. 90cm Chimneys: Which One Is Ideal for Indian Kitchens? Explains how to match chimney size with your cooking habits and hob width.

How to choose the right duct size for kitchen chimney installation

The duct is your chimney’s airway. If the pipe is too small, smoke will get trapped; too large, and you lose suction strength. For a standard 60 cm chimney, a 6-inch (150mm) duct works well. Larger 90 cm chimneys with higher suction rates perform best with 8-inch (200mm) ducts.

Always use flexible duct pipes. They prevent oil buildup, reduce noise, and maintain steady airflow. Keep the duct as short and straight as possible to avoid suction loss.

If your home layout doesn’t allow ducting, a ductless chimney can still keep your kitchen fresh. Glen’s detailed article on What Is a Ductless Kitchen Chimney breaks down how recirculating chimneys work and which homes they suit best.

Where to position the kitchen chimney for the best smoke extraction

The chimney should be installed centrally above the cooktop so it covers all burners evenly. For parallel kitchens, position it along the main counter; for L-shaped kitchens, place it above the longer section. Maintain at least 2–3 inches of clearance from surrounding cabinets for airflow and maintenance.

Compact apartments can still accommodate a chimney without making the kitchen look crowded. Glen’s guide, You Don’t Need a Big Kitchen to Install a Chimney Here’s Proof, shares clever placement tips that work beautifully in small Indian homes.

If you want a practical example, the Glen Designer Push-Button Ductless Chimney 6077 (60 cm, 1250 m³/h) fits perfectly above compact cooktops, offering both strong suction and a sleek design.

Step-by-step kitchen chimney installation process

Proper installation is about precision, not just placement. Start by measuring your hob width, ceiling height, and ideal clearance.

1. Mark the centre of the stove on the wall and align the chimney exactly above it.
   
2. Fix the mounting brackets securely at the right height using strong anchors.
   
3. Mount the chimney and ensure it’s perfectly level.
   
4. Connect the duct pipe (preferably rigid aluminium or PVC) and seal the joints with aluminium tape to prevent air leaks.
   
5. Plug it into a 15-amp power socket with proper earthing.
   
6. Test suction at different speeds to ensure smooth operation.

If you’re planning a recirculation setup, the airflow process is clearly explained in What Is a Ductless Kitchen Chimney.

Common kitchen chimney installation mistakes to avoid

Installing a chimney too high reduces suction power, while placing it too close to the stove exposes it to direct heat. Always seal duct joints properly and leave space around the hood for cleaning access.

Homeowners often overlook filter maintenance. A useful read from Glen’s team, Baffle Filter vs Filterless Kitchen Chimney Guide, helps you choose the right type based on your cooking style.

When to call professionals for chimney installation

If your kitchen has a slanted ceiling, hidden ducts, or custom cabinetry, it’s best to call Glen’s trained technicians. Professionals ensure correct mounting height, duct alignment, and safe electrical wiring, all while keeping your warranty intact.
