Category 1: Fundamentals & Definitions (Questions 1-15)
1. What is the primary purpose of NFPA 211?
A. To regulate the manufacturing of chimney liners.
B. To establish minimum criteria for the installation and maintenance of solid-fuel
burning appliances.
C. To set standards for the sale of fireplaces.
D. To provide guidelines for the design of all residential heating systems.
B. To establish minimum criteria for the installation and maintenance of
solid-fuel burning appliances.
*Explanation: NFPA 211 is the "Standard for Chimneys, Fireplaces, Vents, and
Solid Fuel-Burning Appliances." Its scope covers the minimum safety
requirements for the design, installation, inspection, and maintenance of these
systems.*
2. A "listed" appliance or component is one that:
A. Is the most expensive option available.
B. Has been tested and certified by an independent testing laboratory.
,C. Is approved by the local fire department.
D. Is made of stainless steel.
B. Has been tested and certified by an independent testing laboratory.
Explanation: "Listed" means the equipment or materials meet appropriate
standards or have been tested and found suitable for a specified purpose by a
recognized testing agency like UL (Underwriters Laboratories).
3. What does the "clearance to combustibles" refer to?
A. The distance between the stove and the nearest wall.
B. The required distance between a heat-producing appliance and any combustible
material.
C. The space needed to clean the chimney.
D. The distance from the floor to the bottom of the appliance.
B. The required distance between a heat-producing appliance and any
combustible material.
Explanation: This is a critical safety distance to prevent adjacent wood, drywall,
or other combustible materials from overheating and catching fire.
4. Creosote is a major cause of chimney fires. What is it?
A. A type of insulation used in chimneys.
B. A sticky, flammable byproduct of incomplete combustion that condenses in the
,flue.
C. A special cement used for masonry work.
D. A metal connector between the appliance and the chimney.
B. A sticky, flammable byproduct of incomplete combustion that
condenses in the flue.
Explanation: Creosote is a black or brown tar-like substance that can be flaky,
sticky, or glazed. It is highly combustible and accumulates on flue liners.
5. The term "draft" refers to:
A. The first burn in a new fireplace.
B. The pressure difference that moves combustion air into an appliance and
exhaust gases out.
C. The design of the fireplace opening.
D. The amount of wood loaded into a stove.
B. The pressure difference that moves combustion air into an appliance
and exhaust gases out.
Explanation: Draft is the driving force created by the difference in density between
hot flue gases and the cooler ambient air. It ensures proper venting.
6. An appliance classified as "solid fuel-burning" can use which of the
following?
, A. Natural Gas only
B. Propane only
C. Wood, coal, pellets, or other non-gaseous/liquid fuels
D. Heating Oil only
C. Wood, coal, pellets, or other non-gaseous/liquid fuels
Explanation: Solid fuel-burning appliances are specifically designed to burn
materials like cordwood, coal, wood pellets, and corn.
7. What is the primary function of a chimney liner?
A. To improve the exterior appearance of the chimney.
B. To contain combustion products, protect the chimney structure, and transfer
heat.
C. To provide a base for the chimney cap.
D. To support the weight of the chimney crown.
B. To contain combustion products, protect the chimney structure, and
transfer heat.
Explanation: The liner creates a smooth, insulated, and durable passageway for
hot flue gases, improving safety and performance.
8. A "thimble" is used for:
A. Capping a unused chimney.
