Friday's game will be their first Guinness PRO12 game since Foley's death, and the Ulsterman have prepared a series of tributes to the former Ireland international.
Kiss admits it will be hard for his players to control their emotions but hopes they can channel them in the right way and maintain their position on top of the table.
"You watch that Munster game and you're lost for words when you see the outpouring of emotion from the rugby community," he told the Belfast Telegraph.
"It seems like it'll take forever for it to sink in and become real but we've got a couple of nights to recover, get our heads on and take on Munster.
"There'll be a plaque in the dressing room and there'll be a lot of things done. It's about managing those elements but also being able to crystallise what this game is really about, just like Axel would want.
"We've had it ourselves with Nevin [Spence] and we know there is going to be a lot of emotion.
"We have to accept that and work with it and maybe do something they won't like by winning to stay top of the league."
