UNION, Maine — Investigators have determined an issue with a propane tank was the cause of a fire and explosion on Thursday in Union.
Department of Public Safety spokesman Stephen McCausland said Friday a pair of portable propane heaters had been installed in the two-story farmhouse during renovations, and an issue with either the heaters or the gas line caused a buildup of propane that ignited.
The occupants of the house had been staying elsewhere because of renovations.
The force of the explosions shattered a window and broke walls in a home about 100 feet from the farmhouse.
The two-story farmhouse was destroyed.
