That is the question. No gas in the tank. No flamible items except the interior. No huge cardboard piles. Just 2 X 6 planking for my loft. No huge deal there. Ever hear of spontaneous 2 X 6 ignition? This unit was Cooked by da Man! In order for a job like this to be done you had to have permission and about $500.00 of special chemicals and ignitors.
