Question

80% Efficiency Flue type? Burner type? (Top/Bottom) Heat Exchanger? Inducer fan? Pilot?

a) Single-wall flue, Top burner, Tubular heat exchanger, Yes inducer fan, Standing pilot
b) Double-wall flue, Bottom burner, Plate heat exchanger, No inducer fan, Electronic pilot
c) Direct vent flue, Top burner, Tubular heat exchanger, Yes inducer fan, Electronic pilot
d) Natural draft flue, Bottom burner, Plate heat exchanger, No inducer fan, Standing pilot

Answer 1

The correct answer is b) Double-wall flue, Bottom burner, Plate heat exchanger, No inducer fan, Electronic pilot.

Step-by-step explanation:

The correct answer is b) Double-wall flue, Bottom burner, Plate heat exchanger, No inducer fan, Electronic pilot.

The flue type in this case is a double-wall flue, which provides better insulation and reduces heat loss. The burner is located at the bottom, which allows for better heat distribution. The heat exchanger is a plate heat exchanger, which is efficient at transferring heat. There is no inducer fan, which means that the combustion gases are naturally vented. Lastly, the pilot is electronic, which is safer and more reliable than a standing pilot.
