The general rule of thumb, however, is a 1 inch clearance all the way around for vertical vent runs. And if running the pipe horizontally, it must maintain a 3 inch clearance for the top half of the pipe and a 1 inch clearance for the bottom half of the pipe. Direct vent chimney systems are specialized.

2017/8/243. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas tight compartments, greatly minimising leakage.
