Chimney Installation in Kolkata
Good chimney installation in Kolkata comes down to three things: mounting the hood at the right height above the hob, routing the duct with as few bends as possible, and giving that duct a slight fall so condensed oil drains away from the motor. Get those wrong and even an excellent chimney underperforms. Call 9088855524 to book the authorised Kutchina team.
Key takeaways
- Height: roughly 65–75 cm above a gas hob — too high loses capture, too low is a fire and headroom risk.
- Duct: shortest practical run, fewest bends. Every bend costs you real suction.
- Fall: the duct must slope slightly away from the unit so condensed oil does not run back into the motor.
- Width: the chimney must be at least as wide as the hob, never narrower.
- Free site check before installation — call 9088855524.
What the installation involves
- Site check. We measure the hob, the available wall, and the route to an external vent. This is also when we tell you honestly whether ducted is feasible.
- Position and height. The hood is centred on the hob and set at the correct clearance for your cooktop type.
- Mounting. Fixed to structural wall where possible. A chimney is heavy and vibrates in use — a poor fixing becomes a rattle within months.
- Duct routing. Shortest run, minimum bends, correct diameter, sealed joints, slight fall away from the unit.
- Electrical connection to a suitable point.
- Testing. All speeds, lights, and the auto-clean cycle if fitted. We check actual capture over the hob, not just that the fan spins.
- Handover. How to run it, how often to clean, and what the warranty covers.
Ducted or ductless in a Kolkata flat?
| Ducted | Ductless (recirculating) | |
|---|---|---|
| Where the air goes | Outside the building | Filtered through charcoal, returned to the room |
| Real-world extraction | Clearly better | Lower — heat and humidity stay in the kitchen |
| Ongoing cost | None beyond cleaning | Charcoal filters need periodic replacement |
| Install requirement | Needs a permitted vent route | No vent needed |
Ducted is the better installation wherever it is allowed. In older Kolkata buildings and some housing societies an external vent is not permitted, and ductless is then the workable answer — just go in knowing the trade-off. Our site check establishes which applies to your flat before you buy.
Installation mistakes we are called out to fix
A large share of “my chimney is weak” complaints are installation faults rather than product faults.
Mounted too high. Fitted for headroom rather than performance, so smoke disperses before it is captured. Very common, and no amount of extra suction compensates properly.
Too many duct bends. Each bend adds resistance. A duct with three or four turns can cost a substantial fraction of the rated airflow.
Duct sloping back toward the unit. Condensed oil runs back into the blower and motor instead of away. This is a leading cause of oil dripping and of premature motor wear.
Chimney narrower than the hob. Smoke escapes past both ends of the cooktop no matter how strong the motor is.
If your existing chimney has any of these, it can usually be corrected — see chimney repair or call 9088855524 for a re-installation assessment.
After installation
Kolkata’s humidity keeps deposited oil tacky, so grease accumulates faster here than the manual assumes. Plan for regular cleaning from the start — an AMC schedules it so performance does not quietly decline. Choosing the unit itself is covered on our kitchen chimney in Kolkata guide.

Frequently Asked Questions
What height should a kitchen chimney be installed at?
Roughly 65–75 cm above a gas hob. Higher than that and capture drops off noticeably; lower becomes a heat and headroom problem. The exact figure depends on the model and your cooktop, which is why we set it on site.
How long does chimney installation take?
A straightforward ducted installation is typically completed in a single visit. Complex duct routing, core drilling through a thick wall, or correcting a previous bad fit can take longer. We confirm after the site check.
Do I need ducting for a kitchen chimney?
Ducted performs better and is the right choice wherever a vent route is permitted. If your building does not allow an external vent, a ductless model with charcoal filtration works — accept lower extraction and periodic filter replacement.
Can you install a chimney I bought elsewhere?
Yes, for Kutchina chimneys. Call 9088855524 with the model and we will confirm.
Does bad installation affect suction?
Considerably. Mounting too high, excessive duct bends, or a duct that slopes back toward the unit will all cost real airflow — often more than the difference between two suction ratings.
Do you install chimneys in Salt Lake and New Town?
Yes. Salt Lake, New Town, Kestopur, Rajarhat, Baguiati and Chinar Park are closest to our base, alongside Dum Dum, Barasat, Basirhat, Howrah, South Kolkata, Behala and Garia.
