Pop out center of handle, and remove the screw from center, and remove handle. There should be a little nylon gear like sleeve that will pull out from center. Pull it out, and rotate it one way or the other, a little at a time, and slide it back in. Now just slide your handle on long enough to try it, no need to attach with screw yet until your done. May take a few tries to get it where you want it, then simply put handle back on, secure it with the screw, and snap cap back over screw.

You may have a dirty pilot orifice. Try this. Turn off the pilot by turning the control knob to off. Remove the front panel to get access to the pilot orifice. Use a can of compressed air with attached straw (the same stuff you use to clean computer keyboards) and blow out the pilot orifice, which is inside the pilot assembly where the pilot flame burns. Blow it out from the top and from the sides through the air holes. Then relight the pilot and see if that improves the flame size and color (blue) to heat the thermocouple.

Before calling service technician, read manual for fault finding and possible solutions.
Read manual cover to cover, make sure tankless receives yearly maintenance as outline in manual.
Following links talk about keeping pilot lit, and describe location somewhat. Bosch water wizard has standing pilot light.
1) The manual does not show diagrams you asked for.
2) Website that sells Bosch parts does not show parts for water wizard, nor does Bosch site for parts: Instruction manual says: replace pilot injector
3) Searching "pilot injector for Bosch Water wizard" turns up fixya questions which is generally bad news for do-it-yourselfer because it means information sources are through service technician.
4) As a general rule, tankless are not do-it-yourself repairs or installation because they are affected by so many internal and external factors, including air quality, air flow, venting, other gas appliances, gas pressure, gas supply, water pressure, water flow, plumbing problems, water quality, plus internal parts and including any combination of things listed above..
