Emilio Saladriagas is in critical condition in the burn unit at St. Barnabas Medical Center.
Police say the 62-year-old went to the store to speak to a manager Tuesday. Police say the Newark resident pulled out a bottle of lighter fluid and a cigarette lighter when he was told the manager wasn't available.
Rent-A-Center spokesman Dwight Dumler said the company is concerned about the man.
