hi savannah enthusiasts,
in case you didn't opt to see the comment and problem reports for the
savannah through coral...i wanted to forward this note about ammonia use to
everyone.  if you smell ammonia always close the regulator immediately.
your nose is an excellent ammonia sensor and you should smell it early
enough to warn you into action.

When opening the ammonia regulator, do not tighten it open or open to the
stop point.  this actually pushes the regulator valve physically beyond its
"maximum opening" and causes a leak.  instead just open the regulator until
it spins freely.  there is a lot of play in this middle region and the
needle valve controls the ultimate input, so anywhere in the freely turning
regime of the regulator knob is fine for operation.

i'll do better in the training going forward about making this clear.
