Purchased a new 2011 cy3950. the pics in the manual for which drain is which doesn't seem specific to our model as they don't match up with what we see.

we have 3 valves that go out one drain connection behind a door labeled Gray #1. We also have 1 valve that goes out to another drain connection behind a door labeled Gray #2. nowhere around the valves (push/pull to open/close) does it say which are gray and which are black.

Does anyone have any insider knowledge to know which is which?

I emailed Heartland Customer Service over 5 days ago, but didn't hear back from them.

Help! Many thanks from a first timer!
