Portland Commissioner Dan Saltzman on Monday promoted Deputy Chief Ken Burns to interim chief of the city's Fire and Rescue Bureau.

Burns replaces Chief Erin Janssens, who retires this month after a tumultuous three-year tenure as Portland's first female fire bureau chief. Her time at the helm included an episode in which an assistant fire marshal told a downtown sex club how it could ignore potential fire-code violations, and Janssens' own grabbing of a subordinate in a threatening manner during a meeting.

Burns will serve until the bureau appoints a permanent director. He will not be a candidate for the permanent job, says Saltzman.

Burns joined the bureau in 1990.
