Chimney’s size play an very important role while installation. A big chimney can suck up smoke from your hob even when little displaced. But, if your chimney size matches that of the hob, then its very important to place the chimney directly above it i.e matching it end to end.
If you have a smaller chimney then match the center of the chimney and hob.

2. DISTANCE BETWEEN GAS STOVE AND CHIMNEY
The distance between top of the hob and chimney should be between 26” to 30”. If the distance is below 26” and the gas stove is turned on without any utensil on the burner, chimney may catch fire due to the oil in the collectors . And if the distance between chimney and hob exceeds 36”, chimney cannot take away all the heat and smoke. Thus, the impurities get settle down which makes kitchen shelves oily and dirt.
Distance from hob determines the efficiency of the chimney.
3. CHIMNEY DUCT
In case of ducted chimneys, make sure that the duct should not be more than 12 feet. The most preferred type for duct is Stainless steel and aluminium because of its strength and durability. Most of the chimneys comes with PVC which easily melts in case of excess heat while suction.
Another thing is that, the duct should not contain more number of bends. Bends make it difficult for the smoke to reach the exhaust. Hence, a small pipe with fewer bends is more effective.
4. CUT-OUT FOR CHIMNEY DUCT
In the external wall of the kitchen make a 6-inch-wide and circular opening for the duct. This cut-out should be made at a height of 7 feet above from the floor level on the external wall of the kitchen. In case of no pre-existing hole, contact chimney installer to make a correct hole for installing the chimney in a correct position.
Another way could be by using the cut-out hole of external exhaust fan for passing the duct through it. If you live in rented house or apartments, it is better to go for ductless chimney types to avoid such situations.
