Chimney/Flue Systems Quiz

Which objective involves understanding the layout and features of construction?

• Explain the effects of layout on chimney/flue systems

• State the layout and features of chimney and flue construction

• Identify the components within chimney/flue systems

• Reference termination requirements for chimney/flue systems

What is the objective related to termination requirements for chimney/flue systems?

• List basic inspection and testing procedures

• Explain the operating principles of chimney/flue systems

• Reference termination requirements from relevant documents

• Identify types of 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 reduce air intake.

• Minimize heat loss and maximize fuel efficiency.

• Enhance smoke production and decrease air flow.

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.

• Heat is absorbed, creating a pressure difference called 'side draught' via radiation.

• Air is compressed, creating a pressure difference called 'forward draught' via diffusion.

What is the primary purpose of a chimney or flue system?

• To create an up draught to remove fumes

• To provide heating

• To circulate air within a room

• To cool down the environment

What are the two types of flue designs mentioned?

• Natural draught and room sealed

• Mechanical draught and open sealed

• Natural draught and mechanical sealed

• Room draught and natural sealed

What is the primary function of open flues in heating systems?

• To cool the room

• To create an up draught for combustion

• To circulate water

• To provide electricity

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

• From a separate tank

• From the outside via a vent

• From the combustion chamber

• From the water supply

What happens to the products of combustion in an open flue system?

• They are stored in a tank

• They are released into the room

• They are removed up the flue by natural draught

• They are converted into water

What is the purpose of a fan in an open flue system?

• To cool down the appliance

• To create a positive up draught

• To reduce noise levels

• To increase fuel efficiency
