Liam Allen, from Rotherham, died in hospital after going into a fit from which he never recovered on Saturday, November 23.
The aspiring YouTuber made headlines two years ago when he saved his gran Jenny from choking two years ago.
His family have now released details of his funeral, which will take place on Thursday, December 19.
A procession will take Liam past Badsley Primary School, where he was a pupil, pausing outside the Badsley Moor Lane entrance at 8.30am before pausing at the Tennyson Road entrance so anyone who cannot attend the funeral can be at the school to pay their respects.
Auntie Toni Connell said: “Everyone is welcome to attend but please, I cannot stress enough, make sure it's the right thing for your own children before you bring them.”
The service will take place at East Herringthorpe Crematorium at 9am.
The family have requested those who attend wear something green, as this was Liam’s favourite colour.
Paying tribute to Liam, Toni said: “ “Liam was at the centre of everyone’s world. He was so special in his own way.
“It’s not something that you would never expect to happen, not in a million years.”
Liam’s headteacher Mark Windle described him as ‘thoughtful and kind’ and a ‘real joy’ to have in school.
Green ribbons have been tied on trees and fences outside Badsley Primary School in the youngster’s memory.
