My second home I put a 90 % effecient furnace in my garge. It vented in side so no piping to run except the gas pipe.. For 3 years we always smelled something but figured it was the smell from changing oil etc and those fumes being consumed by the furnace and reburned to make the great smell. when we chose to sell the home the inspecter came in and said we had a leak.. It was in the gas pipe that had to be turned 4 full turns.. my wife said"told you so" so again I had to tell her she was right!!!
