Normal -- probably not intended, but that's how it works.  The current draw
shifts the ground reference a few millivolts more positive than before,
which makes the flame detector light up (the thermocouple actually goes
negative to system ground, so anything that makes the ground more positive
will tend to light the LED).  If that doesn't make sense, I'll try to
explain better when I'm awake.
