Calculating Kitchen Chimney’s Installation Height From the Stove

Among the most important factors when it comes to selecting the perfect chimney is the distance from the stove and the right size of kitchen chimney.

Therefore, as you shop for your new kitchen chimney, make sure you consider this height, its suction power, and the dimensions of the stove. Are you planning to install your appliance today? 

Normally, it is recommended that you let a professional do this task to avoid mess-ups. However, if you have decided to do it by yourself, here is how to calculate the installation height. 

Chimney Height Calculation

It might seem like a simple factor, but using the wrong installation height for your kitchen chimney installation could have serious consequences.

For one, being too close is a recipe for a fire, while too high could reduce the effectiveness. Nonetheless, coming up with this value is a lot easier than you might think. 

All things considered, the ideal chimney height ranges from 20 inches to 30 inches above the stove. This is usually divided into two – 20-24’ and 24-30’ – depending on other factors.

Usually, the manufacturer includes in their manual the required installation height. Alternatively, you can use the features mentioned below to find the exact range of height to use. 

Factors Affecting Height Determination

Type of the stove

Are you using a gas stove? Ensure the height is above 24 inches because anything less than that could be dangerous. The chimney might suck in the flame and catch fire.

However, this risk is minimized when using an induction stove.

Bends and length of the ducts

As you may already know, the number of bends and lengths of the ducts will affect airflow. As such, reducing the chimney’s height may prove to be very effective.

However, this can be dangerous, and the recommended alternative is to use a chimney with high suction power and maintain an optimum height.

 Suction power

This is another factor that may determine your chimney’s height. The higher the suction power, the more the distance between your appliance and the stove.

However, if the suction power is below 800 cubic meters per hour, then the height should not exceed 30 inches.


Chimney installation height may seem like a simple factor, but it affects the overall operation.

If you don’t have the manufacturer’s manual, you can use the three factors mentioned in the article to determine the right installation height.

It is better to have these calculations in place before purchasing your kitchen chimney to avoid frustrations.
