OP says this is a Suburban On-Demand heater. Does that change any advice given here?

Does the On Demand Water Heater even have a tank?

The OP said this is a Suburban On-Demand water heater - no tank to fill, not electric, LP only, different type of resets. Nothing like the usual Suburan water heater

The literature for thes WH says there is a drain for winterization. Looks to be the white or clear tube. Look for a valve on these hoses or a pipe cap to go on them.

You need to find how to shut these lines off, then reverse the position of your three winterizing valves. The unit will never work until the cold water and hot water shut-off valves are open and the bypass valve is closed.

Looked at the manual again

Under draining and storage, it says to remove the service panel to access the drain valve - something to check.

I have the tankless On-Demand heater

During the walk around, the Tech wanted to know if I wanted them to shorten the 2 hoses hanging down, I said if thats all thats got to be done, I could do that. Anyway, any other turning of the valves other then whats in the top pic, water will steam out full force out of the bigger hose. I looked the best I could, will again tonight, for any shut-off valve on either hose that hangs down. Maybe on the hanging hose there has to be a sut-off, or one of those comtraction that hooks on the end to shut-off. I think the solid white hose that hangs down would be the drain for winterizing.
Thanks

Can you post a picture of the diagram that appears partially on the right side of your original picture? Does that hold any clues?

Here is a pic

I believe this is by pass setup, if I turn the 2 center valves, thats currently shut off, water pours out the hose that goes to the ground.

wls, in looking at your first pic you posted of your plumbing station valves, I am noticing the black handles on your black water, galley tank, and I think that's fresh tank.

Are these handles/tanks currently open (pulled out all the way) or is there just that much gap between the black handle and rod end when pushed in.

I was just wondering if you had all the tanks open, and that is why water is perhaps running out a low point drain.

Can you push these handles in any more?

To small to read verbiage but your valve position picture does not look like the drawing. The center valve is open and the drawing shows to be closed but drawing print to small to make out if it is showing by pass or normal.
