ABSTRACT:
A multistage gas fired water heater includes a primary heating tank and a secondary tank mounted vertically over the primary tank with a plurality of primary flues located within the primary heating tank aligned with secondary flues located within the secondary tank. One of the primary flues is constructed to operate as a condensate removal pipe for draining water which forms in the secondary flues. The designated condensate removal pipe prevents water from trickling down the other primary flues or collecting in the flue manifold.
