Explosive Furnace Installation
This is a home that was recently renovated that I was performing a home inspection on for a client. The contractor was on site and decided to turn the gas on at the meter while I was upstairs starting my inspection. He then came upstairs to try to test the gas he had turned on by lighting the gas stove. I then smelled gas in the living room and told him to shut it off! Then I went down to the furnace and the picture is what I found.
Gas had completely filled the duct system by the time he shut off the gas. Had I not stopped him I assume he would have lit the stove and caused the house to explode!
