Which back-pan feature includes flues that extend below the arch rail?

Back-pan features describe how the exhaust paths are arranged relative to the arch rail. The drop flue is the design where the flues extend downward past the arch rail, reaching below it. This specific geometry distinguishes it from other terms: dual conductor refers to electrical pathways, diatomaceous earth is a filtering material, and a defoamer is a chemical used to reduce foaming. So when flues extend below the arch rail, the appropriate term is drop flue.
