Venting Hood Guide for Outdoor Kitchens

Venting Hood Guide for Outdoor Kitchens

Choosing a vent hood for your outdoor kitchen is different from choosing an indoor hood. Experts specifically design these hoods to withstand the heat and moisture of the outdoors. Use our guide to help you choose an outdoor vent hood that’s perfect for your lifestyle, adds style to your home, and takes care of all that smoke that may build up over your grill.


What should I look for?

Outdoor vent hoods come with various specifications, from internal blower speed to CFM’s. It isn’t always easy to make sense of all the jargon, so we’ve created some guidelines to help you choose the perfect item.

Size MattersTo catch the smoke on a breezy day, choose a vent hood that is larger than your grilling surface. This will prevent smoke from building up and escaping around the vent hood. Most grill manufacturers suggest a minimum size. You can stick to their specification, but avoid choosing a smaller hood than the manufacturer recommends. If you can’t find a manufacturer recommendation, our experts suggest choosing a vent hood that is four to eight inches larger than the grill surface.

What are CFM’s?

CFM’s measure how much air a fan moves. It’s important to choose a powerful fan for your outdoor kitchen because it has to overcome wind speed and the smoke produced by your grill. Hoods with a higher number of CFM’s have a more powerful fan. We recommend a hood with a minimum of 1200 CFM’s, but you won’t regret selecting something more powerful for an outdoor kitchen.

Internal blower speedy

Many ventilators offer adjustable speeds for the internal blowers, so your vent hood accommodates various conditions, wind speeds, and smoke levels. Look for this feature if you have variable winds or want more flexibility with your ventilation system. This feature isn’t required, but it might be helpful depending on your individual preferences.

Roof cap and airflow

Before you buy a vent hood, decide whether you’ll use a roof top vent or an outside wall to let the smoke escape. If you’re not sure which is best for your set up, talk to an expert about your options. Roof top vents are usually a more direct way to allow air to escape, but an outside wall might be a better option for your outdoor kitchen.

Positioning of the hood

We recommend about 36” from the base of the counter to the base of the hood. You don’t want it too high or it won’t capture the smoke.  If it is too low, you will be bumping your head.

Vent Sizes

If you’re cooking outside, the vent size is very important. If it’s too small, it won’t catch enough smoke. Choose a vent that is at least 10″. For larger grills, you might want to look for dual vents or other features that increase the total vent size.

Rooftop vent or outside wall?

We recommend about 36” from the base of the counter to the base of the hood. You don’t want it too high or it won’t capture the smoke.  If it is too low, you will be bumping your head.

Warranty issues

It’s important to consult a professional when installing your outdoor kitchen. Excessive heat from an outdoor kitchen could cause premature wear and fade on your shingles. Improper venting may void the warranty on your roof, so be sure your vent follows the guidelines above.
