For gas cooktops, it is typically recommended that the range hood be installed 24–30 inches above the stove. For proper ventilation above your gas cooktop or range, consult your owner's manual and install your range hood at the recommended height.
If you have an electric cooktop, range hoods should be 20–24 inches above the heat source. For gas cooktops, your range hood should be 24–30 inches above the stove. Range hoods have multiple functions such as complementing your cooktop or range and helping clear the air of smoke while you cook.
In general, most installations require a distance from 20" to 24" between the bottom of the hood and the cooking surface. Over a gas range, this distance should be between 24" and 30", unless otherwise specified - in other words read the manual for both the stove and the range hood.
Right distance electric cooktop
We also recommend a maximum distance 80cm in this case. If your range hood is mounted higher than that, it probably won't extract all the cooking fumes.
Gas Hobs: Given the open flame and the heat it produces, there's a greater distance required between the hob and the cooker hood. Generally, the minimum distance recommended is 750mm, but it can vary based on the gas hob's size and power.
For gas cooktops, it is typically recommended that the range hood be installed 24–30 inches above the stove. For proper ventilation above your gas cooktop or range, consult your owner's manual and install your range hood at the recommended height.
1.1, outlines clearances to range hood and exhaust fans. For a new installation, the clearance between the cooking support surface for the cooking vessels and the rangehood shall not be less than 650mm.
Secondly, you'll need to make sure there's enough clearance between the top of your hob and the bottom of your cooker hood. This is known as the hot zone and should be 65cm for electric models and 75cm for gas hobs.
A 30-inch hood over a 36-inch cooktop is not recommended, as it may not effectively capture smoke and odors. For proper ventilation, the hood should be at least 36 inches wide.
Ventilation to the Outdoors (IRC M1503. 1): Residential range hoods should vent to the outside to effectively expel smoke, grease, and cooking odors, maintaining the home's air quality. This requirement is crucial for preventing the recirculation of contaminants within the home.
Installations can vary, so checking the installation instructions to determine space requirements for your specific model is recommended. The following are general minimum clearances for ranges: 1 ½ inches to nearest adjacent sidewall above the cooktop on both sides. 30 inches between the cooktop and a cabinet.
Stove: gas or electric
Make sure you have a 30” clearance between the cooking surface of an electric stove and the bottom of your upper cabinet and a 36” clearance for a gas stove. This means that the bottom of the cabinet with the range hood should be 66" to 72" from the finished floor.
A wood style island range hood should have at least 36” clearance from the cooktop, while a stainless steel range hood will require a 30” clearance.
A range hood with a minimum CFM rating of 300 to 400 is recommended for most residential gas stoves.
If your range top is 30 inches wide, go for a ventilation hood that's 36 inches wide. That way, you'll have an even overhang of 3 inches on each side. You always want your range hood to cover as much space over your range top as possible. That way, it can catch grease and fumes efficiently.
The thumb rule is to select a hood 3 inches wider than the cooktop on both sides. The ideal hood size for a 30-inch cooktop would be a 36-inch range hood.
It's best to install a hood that measures the same size as your cooktop to most effectively capture the grease, odors and smoke coming from any burner or element below.
A range hood should be installed a minimum of 20" above an electric unit and 30" above a gas range. For optimum efficiency, the distance between the cooking surface and hood should not exceed 30".
Gas Ranges require a 6" side wall clearance above the counter height for proper distance from combustible surfaces. Select models may only require a 3" left side wall clearance based upon the burner configuration. Please review model specific Installation Instructions for required dimensions.
No, there's no specific maximum distance, but there is a minimum recommended distance, typically 65cm for electric hobs and 75cm for gas hobs. This is a safe distance that most manufacturers recommend for the optimal performance of their cooker hoods.
Where no dimension is specified in the manufacturer's instructions, the overhead clearance from the highest part of the highest burner of the appliance to the rangehood shall be not less than 600 mm, and not less than 750 mm for an exhaust fan.
For a Whirlpool gas hob of less than 7500W power the minimum distance is 65cm. For hobs over 7500W the minimum distance is 75cm.
Your range hood should extend to cover all back burners and front burners on your cooking station. For most range hoods, 18-22 inches is deep enough for full coverage. However, downdraft vents are slightly larger and require at least 24 inches of depth.
