Current Update!! Instant Download Pdf 1. How is draft measured? A Pounds per square inch (PSI) B Cubic feet per minute (CFM) C Inches in water column D Degrees Fahrenheit - Correct Answer: Draft is measured in inches of water column (IWC) — a very small pressure unit appropriate for the slight pressure differences that drive flue gas flow through a chimney. 2. What is the definition of draft? A The speed of flue gas moving through the chimney B The temperature difference between inside and outside air C The difference of pressure inside and outside the venting system D The volume of air entering the appliance - Correct Answer: Draft is the pressure differential between the inside of the venting system and the outside atmosphere. This difference — caused by buoyancy of hot gases — drives combustion gases up and out of the appliance. 3. What is the easiest solution to 'back puffing' in a stove? A. Extend the chimney height B. Install a barometric damper C. Give it more air D. Clean the connector immediately - Correct Answer: Back puffing is typically caused by insufficient combustion air. The easiest fix is to give the fire more air — opening an air intake or a window slightly to break negative house pressure and restore positive draft. 4. What factor has the greatest effect on flow through a venting system? A Height of the chimney B Temperature of flue gases C Size of the venting system passageway D Number of elbows in the connector - Correct Answer: The cross-sectional area of the venting passageway has the greatest effect on flow. An undersized flue restricts flow severely, while an oversized flue reduces gas velocity and promotes condensation and creosote. 5. What does a barometric draft regulator do? A Increases draft during cold weather B Measures draft in inches of water column C Prevents excessive draft by allowing dilution air into the system D Seals the damper automatically when the fire goes out - Correct Answer: A barometric draft regulator is a counterweighted flap installed in the connector. When draft exceeds the set point, it swings open and admits dilution air — reducing draft to the optimal level and preventing over firing. 6. What problems are created when mortar joints between flue tiles are not smoothed? A Structural cracking of the tile B Increased heat loss through the chimney wall C Turbulence and increased residence time of exhaust gases D Accelerated deterioration of the exterior masonry - Correct Answer: Rough or protruding mortar joints disrupt laminar gas flow, creating turbulence. This slows exhaust movement, increases residence time, promotes creosote deposition, and reduces draft efficiency. 7. What code requires a masonry chimney to have a cleanout if it previously vented a solid or liquid fuel appliance? A NFPA 211 B IRC Section R1003 C NFPA 54 — National Fuel Gas Code D UL 103 - Correct Answer: NFPA 54 (National Fuel Gas Code) requires a cleanout opening when a masonry chimney that previously served a solid or liquid fuel appliance is converted to gas service — to allow removal of accumulated debris. 8. Where can information on the use and installation of gas appliance draft hoods be found? A NFPA 211 B UL 103 Standard C National Fuel Gas Code (NFPA 54) D The appliance manufacturer's label only - Correct Answer: The National Fuel Gas Code (NFPA 54) governs gas appliance installation requirements including draft hood use, sizing, and placement specifications. 9. Where can Category II, III, and IV appliance venting requirements be found? A NFPA 211 Chapter 5 B The National Fuel Gas Code appendix C In the appliance installation instructions D UL 1738 standard only - Correct Answer: Category II, III, and IV appliances have unique venting needs based on flue gas temperature and condensing characteristics. Requirements are specified in each appliance's installation instructions, not a single universal code. 10. What inspection level determines if a wall pass-through is installed properly? A Level 1 B Level 3 C Level 2 D Pre-occupancy inspection - Correct Answer: A Level 2 inspection — which includes video scanning of accessible areas — is required to verify proper installation of a wall pass-through (thimble), confirming clearances, sealing, and structural integrity.
