Chimney and Flue Systems Quiz

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

• Remove debris and filter smoke

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

• Generate heat and circulate warm air

• Condense steam and release pressure

What creates the pressure difference called 'up draught' in a chimney or flue system?

• The cooling of gases

• The rotation of the earth

• The rise of hot gases

• The mechanical fans

What is the basic concept of a chimney or flue system?

• To filter and clean the air

• To create a down draught

• To create an up draught

• To generate heat

Which two flue designs are mentioned in the handout?

• Electric and gas-powered

• Natural draught and room sealed

• Forced draught and open

• Indoor and outdoor

How can the up draught in a flue be created?

• By natural or mechanical means

• By electrical heating elements

• By solar power

• By water pressure

What type of flue is described as the simplest design where the air for combustion is taken from the room in which the appliance is located?

• Forced draught flue

• Natural draught flue

• Room sealed flue

• Secondary flue

What are the two types of room sealed (balanced) flues mentioned in the document?

• Natural draught and artificial draught

• Fan assisted and vent assisted

• Natural draught and fan assisted

• Mechanical draught and static draught

How does a room sealed natural draught system dispose of the products of combustion?

• By using a fan to force the products out of the building

• By evacuating the products through a duct that runs through the combustion air duct

• By releasing the products directly into the room

• By using a filter to clean the products before releasing them outside

What ensures a positive and safe evacuation of all products in a room sealed fan assisted flue?

• A natural draught

• A manufacturer's fan

• A static filter system

• A combustion air duct

Compared to natural draught flue, what is a distinctive feature of the flue in a room sealed fan assisted system?

• It is larger and requires more space

• It is the same size but uses a fan for assistance

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

• It does not require an external wall for installation
