Look on my website -- there are two drawings for water-level and flame
detector circuits.  Flame detector is one of the amplifiers in the
right-hand chip, pin numbers on the schematic.

Water uses the first three amps in the left-hand chip.  The fourth is
spare.  Pin numbers on schematic.

Provides a variable (high) resistance to ground depending on what the water
level is. The green wire from the LED panel is biased high with one megohm,
gets pulled down to variouslevels depending. Ask me any questions after you
take a look at the schematic.
