Which outcome occurs when a gas furnace exceeds maximum flow?

💡 Explanation

Turbulent flow decreases burner efficiency because the Reynolds number increases, causing a transition in the combustion airflow via increased kinetic energy dissipation within the fuel/air mix at the burner; therefore efficiency drops, rather than increased heat transfer via stack condensation.
