Question 1

The _____ is a brick ledge laid level with the bottom of the damper.&#10;A) mantelpiece&#10;B) smoke shelf&#10;C) thimble&#10;D) damper

Accepted Answer

The brick ledge laid level with the bottom of the damper is called a smoke shelf. A mantelpiece is a framing around a fireplace, a thimble is a metal sleeve installed in a chimney to protect combustible materials, and a damper is a device used to control airflow in a chimney.

Question 2

Tests have shown that about five times the amount of air required for good ventilation can be drawn into the room by operating a fireplace.

Accepted Answer

Tests have indeed shown that operating a fireplace can draw in about five times the amount of air required for good ventilation into the room.

Question 3

The area under the ash dump is formed with masonry into a chase or squared hole that leads directly to the end of an air tube.

Accepted Answer

This statement describes the construction of a typical ash dump in a fireplace or stove. The masonry chase forms a compartment below the firebox where ash and other debris can collect. The air tube leads to the outside to allow for ventilation and prevent the buildup of combustible gases.

Question 4

A dummy flue can be added between two flues to balance out the top of the chimney.

Accepted Answer

A dummy flue, also known as a false flue, can be added between two flues to balance out the top of the chimney and prevent downdrafts. It is a common solution for chimneys with multiple flues that are different sizes, as it helps create a uniform size and shape for the top of the chimney.

Question 5

_____ is a term for the current of air created by the variation in pressure resulting from differences in weight between the hot gases in the flue and the cooler air outside the chimney.&#10;A) Rumford&#10;B) Heat source&#10;C) Motion&#10;D) Draft

Accepted Answer

The term for the current of air created by the variation in pressure resulting from differences in weight between the hot gases in the flue and the cooler air outside the chimney is called draft. Therefore, option D is the correct answer. Option A (Rumford) refers to a design for fireplaces and stoves, option B (heat source) is not related to the question, and option C (motion) is too broad and not specific to the context of the question.

Question 6

Basement fireplaces were rare until about 1950.

Accepted Answer

The answer of Basement fireplaces were rare until about 1950....

Question 7

Flashing around a chimney should not be made of _____&#10;A) iron&#10;B) copper&#10;C) aluminum&#10;D) heavy-gauge tin

Accepted Answer

Iron is prone to rust and corrosion when exposed to the elements, making it unsuitable for flashing around a chimney, which requires materials that can withstand weathering and moisture. Copper, aluminum, and heavy-gauge tin are more resistant to corrosion and are commonly used materials for flashing.

Question 8

The Rumford design increased efficiency and heat output of the fireplace.

Accepted Answer

The Rumford design, which was created in the late 1700s by Benjamin Thompson (also known as Count Rumford), improved the airflow and shape of the fireplace, leading to higher efficiency and heat output.

Question 9

A standard _____ is installed in the center forward section of the hearth.&#10;A) damper&#10;B) intake grille&#10;C) ash dump door&#10;D) screen-backed louver vent

Accepted Answer

An ash dump door is typically installed in the center forward section of the hearth to allow for easy removal of ashes from the fireplace.

Question 10

Benjamin Franklin is considered to be the father of the traditional or conventional form of fireplace design and construction in the Chaptered States.

Accepted Answer

Benjamin Franklin is credited with inventing the Pennsylvania Fireplace, which became the basis for the modern traditional style of fireplace design and construction in the United States.

Question 12

When the air coming down the chimney reaches the smoke shelf directly behind the damper, the air is deflected out into the room to be heated.

Accepted Answer

The answer of When the air coming down the chimney...

Question 13

The _____ loses less heat up the chimney than older types.&#10;A) Rumford fireplace&#10;B) Franklin fireplace&#10;C) traditional US fireplace construction&#10;D) conventional form of fire place design

Accepted Answer

The answer of The _____ loses less heat up the...

Question 14

Only masonry materials should be used in constructing a chimney that serves as a fireplace.

Accepted Answer

The answer of Only masonry materials should be used in...

Question 15

Regardless of whether it is a conventional masonry fireplace, Rumford design, or metal heat-form circulating fireplace, the concept of draft and parts of the fireplace remain the same.

Accepted Answer
