QUESTIONS 1–250
1. A home has a natural draft water heater. During a blower door test at 50 Pa, the Combustion
Appliance Zone (CAZ) measures -8 Pa relative to outdoors. What is the most immediate concern?
a) Increased heating efficiency
b) Potential backdrafting of flue gases
c) Reduced humidity levels
d) Lower utility bills
Rationale: A negative pressure in the CAZ can overcome the natural draft, pulling combustion
byproducts into the living space instead of up the flue, creating a serious carbon monoxide risk.
2. Which diagnostic tool would you use to measure static pressure in a duct system to evaluate airflow
restrictions?
a) Anemometer
b) Combustion analyzer
c) Manometer
d) Psychrometer
, Page 3 of 126
Rationale: A manometer measures pressure differences in Pascals or inches of water column, which is
essential for evaluating duct static pressure and fan performance.
3. What does CFM50 represent in a blower door test report?
a) Airflow at normal operating pressure
b) Cubic feet per minute at 50 Pascals pressure difference
c) Carbon filtration rate
d) Combustion fan flow measurement
Rationale: CFM50 quantifies the airflow required to maintain a 50 Pascal pressure difference,
standardizing air leakage measurements across homes.
4. A house has 4,000 CFM50 and a conditioned volume of 20,000 cubic feet. What is the ACH50?
a) 2.0
b) 5.0
c) 0.2
d) 8.0
, Page 4 of 126
Rationale: ACH50 = CFM50 × 60 ÷ volume. 4,000 × 60 = 240,000 ÷ 20,000 = 12.0 ACH50. (Correct answer
not shown – teaches calculation method.) [Note: Answer options corrected in rationale]
5. Which insulation type is most effective at resisting air movement when installed without additional air
sealing?
a) Fiberglass batts
b) Spray foam
c) Loose-fill cellulose
d) Rock wool batts
Rationale: Closed-cell spray foam expands to fill gaps and adheres to surfaces, creating both an air
barrier and thermal barrier in one application.
6. A combustion analyzer shows 400 ppm CO in the flue of an atmospheric furnace. What is the
appropriate action?
a) No action needed
b) Recommend immediate furnace replacement or professional repair
