The protester shouted "Hu is a killer" and "free Tibet" as police pounced on him to extinguish the flames. The man, who said his name was Lhakpa, sustained burns on his legs.
The man and dozens of other Tibetans were protesting against China's occupation of Tibet. Some wore shirts that read "Chinese - cheap quality, cheap friends" and "China get out of Tibet".
Thursday's protests followed other demonstrations held around India by exiled Tibetans during Hu's visit.
A large number of Tibetans gathered in Dharamsala, home of the Tibetan government-in-exile headed by the Dalai Lama, on Wednesday and shouted slogans against Hu for alleged Chinese atrocities committed in Tibet.

alleged Chinese atrocities in Tibet
Chinese troops entered Tibet in 1950 and over the decades closed monasteries and restricted Tibetans from practising their unique blend of religion and culture.
India officially recognised Tibet as part of China in 2003 but continues to provide asylum to about 120,000 Tibetans.
Hu's visit to India is only the second by a Chinese president in six decades.
He is set to travel to Pakistan on Thursday.
