What is the minimum require vertical distance between the pressure relief valve and a overhead wooden structure (such as a deck) on a 100lbs tank at a single family residence. (Section 126.96.36.199) Illustration 6.2 shows an 8' high deck from grade but this appears to be for reference only. Can the tanks be placed under a deck that is only 6' or 5' above grade but still maintains a 50% perimeter opening? Thanks in advance for anyone who can help.
