isotwin condens f 35 e service menu codes?

Hello,
My gas boiler Saunier Duval ISOTWIN CONDENS F 35 E consumes too much gas. I ask for help in obtaining service instructions for this boiler. I am interested in a detailed description of all service menu codes "96" (1,2,3 ... 22) and "35" (23,24,25 ... 36).
Andy.
Thank!

Andy.
