Sample NATE - North American Technician Excellence Practice Questions
Try these questions from our free NATE - North American Technician Excellence practice tests. The correct answer and an explanation follow each question.
What is the primary safety device that shuts off the gas valve if the pilot flame is extinguished on a standing pilot furnace?
- A. Pressure switch
- B. Thermocouple
- C. Limit switch
- D. Flame sensor rod
Answer: B. Thermocouple
The thermocouple generates a small millivolt signal that holds the gas valve open; when the pilot goes out the signal drops and the valve closes.
What is the primary control's 'safety timing' function on an oil furnace?
- A. Prevent the burner from firing more than 3 times per hour
- B. Allow a limited time for ignition then shut down the burner if no flame is proven
- C. Control circulator pump timing
- D. Purge the combustion chamber before ignition
Answer: B. Allow a limited time for ignition then shut down the burner if no flame is proven
Safety timing (typically 45–90 seconds) limits how long unburned oil can accumulate before locking out the burner to prevent explosion.
LP (propane) gas manifold pressure for residential furnaces is typically set to which value?
- A. 3.5 inches WC
- B. 7–11 inches WC
- C. 10–14 inches WC
- D. 0.5 PSI
Answer: B. 7–11 inches WC
Propane furnaces require higher manifold pressure than natural gas, typically 10–11 inches WC, because propane has different combustion characteristics.
What is a condensate drain trap used for on a high-efficiency furnace?
- A. Trap combustion gases before they exit
- B. Prevent flue gases from backing up through the condensate drain while allowing water to drain freely
- C. Filter particulates from the condensate water
- D. Reduce drain line vibration
Answer: B. Prevent flue gases from backing up through the condensate drain while allowing water to drain freely
The condensate trap maintains a water seal that blocks furnace gases from escaping through the drain while permitting condensate to flow out.
