Fire officials say they're investigating the fire at West 40th Street and Seventh Avenue. One other manhole cover has also blown off.
No injuries have been reported. The incident was reported at about 1:40 p.m. Monday.
A Con Edison spokesman says smoking underground electric cables caused the fire. No power outages have been reported.
A fire official said earlier that firefighters were checking carbon monoxide levels in the basement of a nearby building.
