Chimney and Flue Systems Quiz

What is one of the objectives related to chimney/flue systems?

• Explain the effects of weather on chimney/flue systems

• Identify the components within chimney/flue systems

• Describe the history of chimney/flue systems

• Discuss the economic impact of chimney/flue systems

Which objective involves understanding the layout and features of chimney and flue construction?

• Explain the operating principles of chimney/flue systems

• State the layout and features of chimney and flue construction

• Reference termination requirements for chimney/flue systems

• List basic inspection and testing procedures for chimney/flue systems

What are the two operating principles for any chimney or flue system?

• Remove combustion products to the outside and draw in air for combustion.

• Increase combustion temperature and decrease air intake.

• Reduce air pressure and increase fuel consumption.

• Enhance fuel efficiency and minimize heat loss.

What principle do chimneys and flue systems work on?

• Hot gases rise, creating a pressure difference called 'up draught' via convection.

• Cold air descends, creating a pressure difference called 'down draught' via conduction.

• Hot gases fall, creating a pressure difference called 'down draught' via radiation.

• Cold air rises, creating a pressure difference called 'up draught' via diffusion.

What are the two types of flue designs mentioned?

• Natural draught and room sealed

• Mechanical and electrical

• Open and closed

• Vertical and horizontal

How is air for combustion supplied in appliances with open flues?

• Through a closed circuit

• From the outside via a vent

• Directly from the fuel source

• Through an electric fan

How do room sealed (balanced) flues draw air for combustion?

• From inside the room.

• From a separate air supply.

• Directly from outside.

• Through a chimney.

Where are both the combustion air and products of combustion situated in a room sealed natural draught system?

• Inside the building

• In separate locations

• In the same position outside the building

• In the basement

How does a room sealed fan assisted flue work compared to a natural draught flue?

• It works the same way but uses a fan for forced evacuation.

• It works without any fan assistance.

• It is larger and less efficient than a natural draught flue.

• It does not require any evacuation of products.

What is an advantage of a room sealed fan assisted flue over a natural draught flue?

• It is much smaller and can be positioned in more places.

• It requires no maintenance.

• It is more expensive to install.

• It does not require a fan.
