A problem with the heating system created a strange odor at East Hartford High School and caused school officials to evacuate the building Thursday morning.
School officials said there was a mechanical failure with the heating system and caused an odor that was smelled by people in the library.
Because of the odor, school officials evacuated the building around 7:30 a.m. Fire officials were called to the building to investigate the odor.
Students were allowed back into the building around 8 a.m.
No injuries were reported.
