Faye Chattaway, Harry's sister, told BBC CWR that Harry worked at a supermarket on the night shift and "only worked so he could afford to buy Coventry City things".
"His whole life was Cov and he had been going to matches since he was eight", she added.
Harry, from Allesley, died earlier this month. Jones hopes that the applause on Saturday will spread awareness of his friend's life.
"To have something like 32,000 people clap for Harry, and maybe even all of the fans in the stadium, will be remarkable to hear," Jones said.
He added: "He was a fantastic lad and I would be amazed and grateful if people joined in on Saturday".
