Why a 90 cm Kitchen Chimney Is Recommended for a 3-Burner Gas Stove

Choosing the correct kitchen chimney size is just as important as choosing the right suction capacity, motor and filter technology. One of the most common questions customers ask is:

“Can I use a 60 cm chimney for a 3-burner gas stove?”

Although a 60 cm chimney may physically fit above some 3-burner stoves, a 90 cm kitchen chimney is generally the better and safer choice for a standard wide 3-burner stove, especially in Indian kitchens where frying, tadka, masala cooking and high-flame cooking produce significant smoke, oil vapour and heat.

The Basic Rule: Chimney Should Cover the Cooking Area

The most important principle when selecting a chimney is coverage.

A kitchen chimney should ideally be equal to or wider than the effective cooking area of the stove or hob. The chimney hood needs to capture smoke and oily vapours as they rise from all the burners.

For example:

• 2-burner compact stove: 60 cm chimney is generally suitable.
• 3-burner stove: 90 cm chimney is generally recommended.
• 4-burner wide stove/hob: 90 cm chimney is usually recommended.

However, burner count alone should not be used to select chimney size. Always measure the actual width of the stove or hob.

Why Is a 60 cm Chimney Not Ideal for Many 3-Burner Stoves?

A 60 cm chimney provides approximately 600 mm of hood width. Many modern 3-burner gas stoves are wider than this, or have their outer burners positioned close to the edges.

When cooking on an outer burner, smoke, steam and oil vapour do not always travel vertically upward. They spread sideways because of air movement, ceiling fans, heat and cooking activity.

If the chimney is narrower than the cooking zone, some smoke can escape from the sides instead of entering the chimney.

This may result in:

• More oil deposits on kitchen cabinets and walls
• Smoke and cooking smell remaining in the kitchen
• Grease accumulation around the chimney
• Reduced effectiveness when multiple burners are used
• More frequent kitchen cleaning

Even a chimney with high suction capacity cannot fully compensate for inadequate hood coverage.

Why Is a 90 cm Chimney Better for a 3-Burner Stove?

A 90 cm chimney provides approximately 900 mm of coverage, giving a wider capture area above the stove.

This extra width is particularly useful when two or three burners are operating simultaneously. Smoke generated from the left and right burners has a better chance of entering the chimney’s capture area.

For Indian cooking styles involving deep frying, dosa, chapati, tadka, curries and high-flame cooking, wider coverage can make a noticeable difference.

60 cm vs 90 cm Chimney for a 3-Burner Stove

Feature	60 cm Chimney	90 cm Chimney
Hood Width	Approx. 600 mm	Approx. 900 mm
Best suited for	Compact cooking areas	Wider cooking areas
Typical choice	2-burner stove	3 & 4-burner stove/hob
Side Smoke Capture	More limited	Better
Multiple Burner Cooking	Depends on stove width	Generally better
Indian Heavy Cooking	Can be restrictive	More suitable

Chimney Size and Suction Capacity Are Different

Customers sometimes assume that a 60 cm chimney with 1500 m³/hr suction will necessarily perform better than a 90 cm chimney with similar suction.

These are actually two different factors.

Chimney width determines the smoke-capture area, while suction capacity determines how much air the chimney can move.

For good performance, you need both adequate coverage and suitable suction capacity.

Therefore, choosing a powerful motor but installing a chimney that is too narrow for the stove may still allow smoke and grease to escape from the sides.

Can a 60 cm Chimney Ever Be Used for a 3-Burner Stove?

Yes, in some cases.

It is better not to say that a 60 cm chimney can never be used with a 3-burner stove. Some compact 3-burner models may be narrow enough for a 60 cm chimney.

The correct method is to measure the stove first.

If your 3-burner stove is wider than the chimney or the outer burners extend significantly beyond the chimney’s capture area, choosing a 90 cm chimney is recommended.

This is why many dealers and installers recommend 90 cm models for standard 3-burner and 4-burner cooking setups.

How to Choose the Correct Chimney Size

Before purchasing a kitchen chimney, check:

1. Measure your stove or hob width
Measure from the left edge to the right edge.

2. Check burner positioning
A stove may have three burners, but the distance between the outer burners is more important than burner count alone.

3. Select adequate chimney width
The chimney should ideally cover the cooking zone properly.

4. Consider your cooking style
Frequent frying and high-flame Indian cooking usually benefit from wider capture coverage and appropriate suction.

5. Check installation conditions
Chimney height above the stove, duct length, duct bends and outlet size can also affect real-world performance. Always follow the chimney manufacturer’s installation recommendations.

Final Recommendation

For a standard 3-burner gas stove, a 90 cm kitchen chimney is generally the preferred choice because it provides wider coverage and better capture of smoke, steam and oily vapours from the outer burners.

A 60 cm chimney is mainly suited to compact cooking areas and many 2-burner stoves, although it can work with certain compact 3-burner models when the cooking area fits properly underneath it.

Therefore, don’t select your chimney only by burner count.

Remember This Simple Rule:

Measure the stove first → Check the outer burner spread → Choose a chimney that adequately covers the cooking area.

Choosing the correct chimney width can provide better smoke extraction, cleaner kitchen walls and cabinets, less grease accumulation and a more comfortable cooking environment.
