I have a chimney with 2 flues for 2 fireboxes. The previous owner installed gas logs in both fireboxes. The gas lines were run outside the house then drilled through the chimney into the fire boxes. On the upper fire box the gas line actually runs through the flue for the lower firebox so that the hot gases pass the gas line. The chimney sweep said they never saw that before and didn't know if that was ok or not. I don't use the fire places a lot but I'm wondering if this is ok or if this is dangerous.
