Shawn Landa, 47, has been charged with several counts of arson, criminal mischief and causing or risking catastrophe for the Oct. 12 explosion, the Pittsburgh Post-Gazette reported.
A criminal complaint against Landa said the explosion was a suicide attempt.
It said Landa was "depressed and down on himself" when he broke a gas line that fed gas logs in his basement, and then turned the gas on before falling asleep in a chair upstairs.
"He said that he fell asleep and woke three to four hours later," the complaint says. "At this time, he grabbed a cigarette and lighter. When he struck the lighter, the house blew up."
Investigators said Landa told them he was influenced by a movie about the Hindenburg.
"This gave him the idea to blow up the house," the complaint says.
