Question 1

The main components of the chimney are the flue, lining, anchors, cap, and spark arrester.

Accepted Answer

The main components of a chimney are indeed the flue, lining, anchors, cap, and spark arrester.

Question 2

The ____ is the opening inside the chimney that allows smoke and combustion gases to pass from the firebox away from the structure.&#10;A) damper&#10;B) flue&#10;C) chimney cap&#10;D) chimney liner

Accepted Answer

The flue is the opening inside the chimney that allows smoke and combustion gases to pass from the firebox away from the structure. A damper is a device used to regulate the flow of air in and out of the firebox, a chimney cap is a cover that sits on top of the chimney to keep debris and animals out, and a chimney liner is a protective lining inside the chimney that helps to prevent fires and damage to the chimney.

Question 3

In areas subject to seismic damage, a minimum of _____ vertical reinforcing bars 1/2&#34; (13 mm) in diameter (#4) must be used in the chimney.&#10;A) two&#10;B) three&#10;C) four&#10;D) six

Accepted Answer

In areas subject to seismic damage, at least four vertical reinforcing bars 1/2" (13 mm) in diameter (#4) should be used in the chimney. This is to ensure the chimney can withstand the potential shaking caused by earthquakes.

Question 4

The ____ is a masonry or metal covering that may be placed over the flue for protection from the elements.&#10;A) flue&#10;B) chimney hood&#10;C) chimney cap&#10;D) chimney liner

Accepted Answer

The answer of The ____ is a masonry or metal...

Question 5

Altering the shape of the firebox will also decrease the amount of air radiated back to the room.

Accepted Answer

Altering the shape of the firebox can affect how the fire burns and how heat is distributed, but it primarily influences the efficiency of the combustion process and the direction of heat transfer, not the amount of air radiated back to the room. Air radiation is more about the heat emitted from the fire and surfaces, not air movement.

Question 6

The ash dump is the space below the fireplace where the ashes can be stored.

Accepted Answer

The answer of The ash dump is the space below...

Question 7

The size of the ____ should be given much consideration, since it is important for the appearance and operation of the fireplace.&#10;A) hearth&#10;B) ash dump&#10;C) ash pit&#10;D) fireplace opening

Accepted Answer

The fireplace opening is the primary point of interaction between the user and the fire, and it significantly influences how the fire is perceived and how it functions. The size of the opening will determine how much visibility one has of the flames, how much heat is given off, and even how much firewood can be burned at once. The other options (hearth, ash dump, and ash pit) are important components of a fireplace, but their size does not have as much impact on the appearance and operation of the fireplace.

Question 8

A(n) ____ is a screen placed at the top of the flue inside the hood to prevent combustibles from leaving the flue.&#10;A) spark arrester&#10;B) flue&#10;C) hearth&#10;D) ash dump

Accepted Answer

A spark arrester is specifically designed to prevent combustible materials from leaving the flue and potentially causing a fire or other hazards. A flue, hearth, or ash dump do not have this function.

Question 9

The fireplace opening is the front of the firebox.

Accepted Answer

The fireplace opening is indeed the front of the firebox.

Question 10

The ____ is where the combustion of the fuel occurs.&#10;A) chimney&#10;B) firebox&#10;C) smoke chamber&#10;D) damper

Accepted Answer

The firebox is the area within a fireplace, stove, or furnace where the fuel is burned. The chimney carries the smoke out of the combustion chamber, the smoke chamber connects the firebox to the chimney, and the damper regulates airflow, but none of these are where the actual combustion occurs.

Question 11

The ____ is the floor of the fireplace and consists of inner and outer parts.&#10;A) hearth&#10;B) firebox&#10;C) ash pit&#10;D) ash dump

Accepted Answer

The answer of The ____ is the floor of the...

The answer of When drawing fireplace elevations, you should place...

Question 13

A ____ is located at the bottom of the smoke chamber behind the damper.&#10;A) chimney liner&#10;B) flue&#10;C) smoke shelf&#10;D) chimney

Accepted Answer

The answer of A ____ is located at the bottom...

Question 14

When drawing a fireplace section, which layer should you use to represent all finishing materials that extend beyond the cutting plane?&#10;A) DETL MBND&#10;B) DETL OUTL&#10;C) I ELEV OUTL&#10;D) I ELEV FNSH
