Tributes left at the stadium are to be moved to a memorial area.
Leicester will build a statue outside the King Power Stadium in tribute to their much-loved late chairman Vichai Srivaddhanaprabha.
Former manager Nigel Pearson and one-time director of football Steve Walsh were among the early arrivals, while as downpour gave way to sunshine a rainbow appeared in the sky near The King Power Stadium.
Boss Claude Puel admitted preparations for the Burnley game had been hard after a 12,000-mile round trip but said it was important to the players to pay their respects.

It was under Vichai's ownership that Leicester crafted one of the biggest fairytales in English football history by winning the 2015/16 Premier League, having started the season as 5,000-1 outsiders for the title.
Srivaddhanaprabha's name will be embroidered on the players' match shirts during the first half, while their second-half shirts will bear the embroidered poppy symbol, the club said.
Players and staff flew to Bangkok after Saturday's 1-0 win at Cardiff to attend Mr Srivaddhanaprabha's funeral and returned on Tuesday.
The club plan to hand out commemorative scarves, pin badges, banners and souvenir programmes at Saturday's game, which has also been designated the club's annual Remembrance Fixture.

Puel has admitted getting the players ready for the game against struggling Burnley had been tough.
"It's not easy to prepare this game, but the togetherness between us all, it's a good feeling, a good energy, a fantastic strength", he added.
"In the last game, we found the right balance between emotion and concentration, and focus on our game".
Burnley forward Chris Wood, who spent two years at Leicester from 2013 until 2015, said the day would be "filled with emotion".
Supporters braved the pouring rain as they made their way through the streets towards the ground for the first home match since the tragedy holding Leicester flags and wearing club shirts, some with "Vichai" on the back.More news: 5 people found dead in vehicles torched by fire
