Sea Pines resident Mike Schilder watches Hilton Head Island firefighters clear debris Thursday after an ethanol leak beneath his home's fireplace ignited wooden framing inside a wall. Susan Schilder, his wife, said she called 911 after seeing flames between the fireplace and the wall at 2:50 p.m. A smoke alarm sounded about 45 minutes after the fireplace insert was filled with ethanol. The fire caused between $500 and $1,000 in damage to the home off Governors Road.
