and _______.
Correct Answer: annually, upon a real estate transfer
Explanation: Annual inspections catch problems early; transfer
inspections ensure new owners inherit safe systems.
,5. Two major factors that affect draft are ______ and ______.
Correct Answer: temperature differential and chimney height
Explanation: Warmer flue gases and taller chimneys increase draft
force.
6. Which of the following is not a factor of combustion efficiency?
(time, wind speed, turbulence, temperature)
Correct Answer: wind speed
Explanation: Wind affects chimney draft but not the combustion
efficiency of the appliance itself.
7. Rabies is not carried by ______.

for flammable liquids, grease, and oil?
Correct Answer: Class B
Explanation: Class B extinguishers are designed for flammable
liquids and grease fires.
12. The area of a fireplace chimney flue cannot be greater than
twice the area of the woodstove appliance outlet on an exterior
chimney: true or false?
Correct Answer: True
Explanation: NFPA 211 limits flue area oversizing to prevent
excessive cooling and poor draft.
13. Cleaning the smoke shelf is not always necessary, unless
there is a fireplace insert installed: true or false?
Correct Answer: False
Explanation: The smoke shelf collects debris in any fireplace and
must always be cleaned.
14. A 24 gauge sheet metal panel with 1-inch airspace will
reduce clearance to combustibles by (when used as a wall
protector) _______.
Correct Answer: 66%
Explanation: NFPA 211 allows 66% reduction with proper shielding
and airspace.
15. According to NFPA 211, solid fuel-burning appliances can be
installed in a garage:
Correct Answer: Never
