Chimney draft regulations

To maintain a proper amount of heat in the fireplace and thus in the home, the chimney needs to have a good chimney draft. This way, you will save more money on energy bills. Poor draft, means you will use up more fuel to maintain the fire.

Chimney airflow

Chimney draft appears when hot air rises through the chimney and exists it and air is sucked down into the fireplace or stove. This way, the fire is always fed with oxygen and maintained.

Draft regulations

A well built chimney structure is needed in order to have a proper amount of draft and a properly maintained fire.

Flue issues

A flue must be 25% larger than the pipe that connects the stove or fireplace to the chimney. The flue is essentially a  chamber through which the smoke passes, goes into the chimney and then exists into the atmosphere.


A fireplace or stove should be as close to the chimney as possible. The pipe connecting a stove to a chimney shouldn’t be longer than 10 feet.


A taller chimney offers a better draft. In a tall chimney, a draft can be lessen, whilst in a short chimney, it can’t be increased. The taller the chimney the better.


Bends in the pipe system of the chimney will reduce draft. The system must be as straight forward as possible.


A large chimney diameter means a less efficient draft. This is because of the smoke that cools faster than it should and doesn’t exit the chimney. If the chimney is wide, a smaller diameter flue can be used to compensate the size and make the draft more efficient. You can save money over a long period of time if you have a properly built chimney.
