Why are open flues called 'open'?

• Because they are open to the room in which the appliance is installed.

• Because they are open to the outside air.

• Because they are open to the basement.

• Because they are open to the attic.

How do open flues work?

• By the principle of natural updraught created by the heat of the flue gases.

• By the principle of natural downdraught created by the heat of the flue gases.

• By the principle of natural updraught created by the cold of the flue gases.

• By the principle of natural downdraught created by the cold of the flue gases.

Where is the combustion air taken from in an open flue system?

• From the room where the appliance is situated.

• From the outside air.

• From the basement.
