Steam leaking from hot water in the boiler room set off smoke alarms at the Constans Theatre at about 11:45 p.m. Wednesday, said Bob Estling, coordinator for UF's Physical Plant Division.
Estling said there were no damages to the building, and no one was injured.
"I don't think it was a big leak but definitely one we wanted to get fixed," Estling said.
David Kramer, a UF building code administrator who makes sure all installments follow Florida Building Code requirements, said a release valve that lets out steam from the boiler had shut down. This built up pressure and steam "spilled" out of the boiler and rose to the top of the building where it set off the fire alarms, Kramer said.
After Gainesville Fire Rescue arrived, the incident report stated that Lenny Alongi, a UF maintenance employee, reported to the building's boiler room upon request from University Police Department officers.
Maintenance personnel entered the building with the fire rescue crew to secure steam pipes, the report stated.
Estling said shutting off the wrong valve could have caused an explosion.
