Most furnaces will have at least 2 internal drains, typically one for the heat exchanger and one for the vent, usually at the inducer outlet or on the inducer housing. While it does require a certain temperature (not heat) for combustion to get started it’s an exothermic reaction meaning energy is released from the reaction which is why we love it so much for heating. Additionally, the inducer motor would suck air through the drain if it weren’t trapped, which could affect combustion, and would prevent proper drainage. … If cant do this then I wont be able to use a condensation trap.
