The chimney would also draw in the fresh air to defeat the point of having one in the first place and will become hard to choose an optimum height that does not undermine either safety or the intended function.
  • The fitting or installation’s height typically vary between 21 and 30 inches depending on the kind of gas stove being installed.

For example, if a chimney width of 60 cm is ideal for a furnace with 2-4 gas burners, or a width of 90 cm is ideal for a furnace with 3-5 gas burners.

The Distance between the Stove/Cooktop and the Chimney

When consuming a kitchen chimney, this chimney which should be between 24 and 30 inches in ideal circumstances should always be considered. If the distance is less than 24 inches so it may result in the chimney hood catching fire. If the height is more than 31 inches so it will reduce the exhaust rate. In each of these instances that the chimney will be completely ineffective and therefore the proper height of the kitchen chimney is critical for the efficient operation of the appliance.

4. The Ductwork in the Chimney

It always goes for a duct that is no more than 12 feet in length to save money and a longer duct leads to more bends each of which acts as drawbacks for the gases to pass through.
