1. Calculate the Correct CFM for Powerful Smoke Extraction

Pin this essential CFM guide to your ‘Outdoor Kitchen’ planning board!

What You Need to Know

• CFM Explained: CFM stands for Cubic Feet per Minute and measures the volume of air the hood moves. Outdoor kitchens require higher CFM (typically 1200+) due to crosswinds and open space.
• BTU-Based Calculation: A common industry standard is to have 1 CFM for every 100 BTUs your grill produces. For example, a 100,000 BTU grill needs at least a 1000 CFM hood.
• Always Go Higher: For outdoor use, it’s always better to have more power than you need. Look for hoods in the 1200-2000 CFM range for most residential grills.

What To Do

1. Find Your Grill’s BTUs: Check your grill’s manual or manufacturer website for the total BTU output of all main burners.
2. Calculate Minimum CFM: Divide the total BTUs by 100. (e.g., 120,000 BTUs / 100 = 1200 CFM).
3. Select a Hood: Choose an outdoor-rated range hood that meets or exceeds your calculated minimum CFM.

Pro-Tip: Consider the total capture area, not just CFM. A deeper hood (24-27 inches) will capture smoke more effectively than a shallow one, especially on breezy days. This is a key aspect of capture efficiency metrics.

2. Choose Weather-Resistant, Outdoor-Rated Materials

Don’t let rust ruin your investment! Pin these material tips for later.

What You Need to Know

• Indoor vs. Outdoor: You cannot use an indoor range hood outside. They lack the weather resistant construction, sealed electrical components, and corrosion-resistant materials needed to withstand humidity, rain, and temperature changes.
• 304-Grade Stainless Steel: This is the industry standard for high-quality outdoor appliances. It offers excellent corrosion resistance and durability for most environments.
• 316-Grade Marine Grade Stainless Steel: If you live in a coastal area with salt in the air or have a saltwater pool, upgrading to 316-grade steel is critical for preventing rust and ensuring longevity.

What To Do

1. Verify the Material: Always check the product specifications for “304 stainless steel” or “outdoor-rated” construction.
2. Assess Your Climate: If you’re within 50 miles of the coast, prioritize hoods made from 316-grade (marine grade) stainless steel.
3. Check Electricals: Ensure the hood is specified as “UL listed for outdoor use,” which means the wiring and motor are sealed against moisture.

Pro-Tip: Look for hoods with “double-lined” or “dual-wall” construction. This adds rigidity, protects the finish from heat discoloration, and is a hallmark of a professional grade outdoor hood.

3. Select the Right Size & Mounting Height

Size matters! Pin this guide to get your outdoor hood placement just right.

What You Need to Know

• Sizing Rule: Your outdoor range hood should be at least one size larger than your grill. It should overlap the cooking surface by 3 to 6 inches on each side to create a larger “capture area” for smoke and fumes that can drift in the open air.
• Mounting Height: The ideal height is between 30 and 36 inches above the cooking surface. Any lower can be a fire hazard and obstruct your view. Any higher, and the hood loses its effectiveness at capturing smoke.
• Safety Clearance: Always follow the manufacturer’s specified clearance requirements from combustible materials.

What To Do

1. Measure Your Grill Width: Determine the exact width of your grill’s cooking surface.
2. Calculate Hood Width: Add 6 to 12 inches to your grill’s width. For a 36-inch grill, you should look for a 42-inch or 48-inch hood.
3. Plan Your Mounting: Measure 30-36 inches up from the grill grates to determine the final position for the bottom of the hood.

Pro-Tip: When planning, account for the full depth of your grill, not just the width. A hood with a depth of at least 24 inches is crucial for capturing smoke from the front burners of a large, built-in grill.

4. Determine Your Mounting Type: Wall Mount vs. Island Mount

Wall or island? Pin this to help you decide on the perfect setup!

What You Need to Know

• Wall Mount Hoods: These are the most common type and are designed to be installed on an exterior wall directly above a grill that is placed against the house or a back wall of the patio.
• Island Mount (or Ceiling Mount) Hoods: These are designed for outdoor kitchen islands where the grill is in the center of the space. They are finished on all four sides and hang from the ceiling or pergola structure above. They are typically more expensive and require more robust support.

What To Do

1. Analyze Your Layout: If your grill or cooktop is against a permanent wall, you need a wall mount hood.
2. Check for Islands: If your grill is located in a freestanding BBQ island with open space on all sides, you need an island mount hood.
3. Plan for Support: For island mounts, consult with a contractor to ensure your ceiling or overhead structure can safely support the weight of the unit and conceal the ductwork.

Pro-Tip: Island hoods need to be more powerful (higher CFM) than wall mount hoods of the same size. The wall behind a grill helps channel smoke upwards, but an island grill is exposed to cross-drafts from all directions, requiring more suction to be effective.

5. Prioritize Ducted Ventilation for True Smoke Removal

Get the smoke out! Pin this reminder to always choose ducted ventilation outdoors.

What You Need to Know

• Ducted (Vented): This is the correct and only effective choice for an outdoor kitchen. A ducted hood uses ductwork to physically transport smoke, grease, heat, and fumes from the cooking area to the outside of the covered patio space.
• Ductless (Recirculating): These hoods are NOT suitable for outdoor use. They work by pulling air through filters (typically charcoal) and then releasing it back into the space. They cannot handle the heavy smoke from a grill and do not remove heat.

What To Do

1. Confirm the Model is Ducted: Only consider range hoods that are specified for ducted or vented installation.
2. Plan the Duct Path: Determine the shortest, straightest path for the ductwork to exit the covered patio area—either through a side wall or vertically through the roof.
3. Use Rigid Ducting: Use smooth, rigid metal ductwork, not flexible ducting, to maximize airflow and minimize grease buildup. Ensure all joints are properly sealed.

Pro-Tip: For optimal performance, use the duct size recommended by the manufacturer (often 8″ or 10″ round ducting). Using a smaller duct will restrict airflow, reduce CFM, and increase noise.

6. Compare Top Brands and Understand Warranties

Ready to choose a brand? Pin this comparison of the top players in outdoor ventilation.

What You Need to Know
