That would be "parts per million", I think it should be well within safety
measures. Sometimes the mercapan odor they add to the gas can permeate
everything that contacts the gas and creates the smell that the nose can
recognize. I would keep check on it, as the reading did fluctuate and if
something is leaking as the load changes, it may leak more at a later time.


Just curious, what is mercapan?
Yes, I know it's the odorant in the gas, but what I am asking, WHAT
IS THIS SUBSTANCE?
