To let the smoke from the fireplace go out
That way they catch all the hot air and vapour before pumping it out to a vent on the roof

If there is a leak from the ceiling in your home, it needs to be fixed.
'cause hot air always goes up so ventilators and exhaust fans are built near the ceiling to let out hot air and bring cool air.
It is a matter of common observation that furnaces in various factories are provided with very tall chimneys. Fresh air is drawn through a hole near the bottom end of furnace ,while smoke (being hot ) is driven out through the chimneys If the chimneys is removed flame cannot sustain properly .Moreover ,the temperature of the furnace in that case be lesser .

The plural form of the noun chimney is chimneys. The plural possessive form is chimneys'.
Hot air rises because it is less dense than cold air, leading to a concentration of warmer air near the ceiling. This phenomenon is known as convection. Heat energy also tends to accumulate near the ceiling due to factors like poor insulation and the heat distribution from various sources within the room.
The hot air is lighter than the cool air so it floats to the ceiling.:)
Cooking odors are usually found in the warmer air around stoves and ovens. This air typically rises to the ceiling. Most exhaust fans are either directly above the stove or in the ceiling above the cooking surfaces. Exhaust fans are more efficient at removing cooking odors than recirculating fans (which use charcoal filters).
