Has anyone encountered the situation where the odorant smell from the burner gas supply changed when the gas was not used for several months?  ; If so, any explanation why?
 
The individual who posed this question to me said that his "lost i ts rotten smell and now smells slightly musty and is much less noticeable".
 
Thanks ... Jim
