Water Heater Valve positions on 2018 Classic

Trying to help a neighbor with 2018 30 foot classic. Can someone who has one please tell me what the correct valve positions on the attached photo needs to be for summer "Service" mode? We have a photo from Alde but the layout looks nothing like this and I can't make heads or tails to make sure they are correct, or in some sort of bypass mode. Manuals are useless. Much thanks in advance.

Thought it through and think I figured it out. #1 OPEN to allow cold water to enter Mixing Valve. #3 OPEN to allow flow of mixed water to trailer; #2 CLOSED to avoid adding more cold water to mixed water downstream from mixing valve. I can make sense of these for winterizing later and bypassing to use Antifreeze in the plumbing. But there must be another valve hidden further back that feeds the boiler with water, that would need to be shut to avoid filling tank with antifreeze?

Read the manual on winterizing and go back thru these threads on winterizing. Your valve assessment looks to be on point. I've talked to Alde a couple of years ago, they suggest putting Anti-Freeze in the boiler, AS blows out the entire system only.

I've winterized three times, but this year on our way back from FL I only blew out the lines and hot water tank, so when we go out again we shall see if blowing out only worked.

The hidden one is on the rear facing side of the unit feeding into the Alde Flow

I know the ‘17 are different from the ‘18, even the early ‘18 are different from the ones being built and sold now but in the ‘17 there is no such thing as summer service mode. Is your friend in need of Hot Water and not needing heat? Guessing that is the question. I sat at JC for a week and looked at the guts of as many Classic as I was allowed, 7. No 2 were exactly the same, they were close but not identical. Just saying....

Number 1 valve appears to be closed. That valve should be open.

On our 2018 Classic 30' all valves are open except (what you have labeled #2) is closed for normal operation.

What he said, high and deep against the boiler, or it was, when found several months ago by another.

Agree. Note valve #2is the mixing valve bypass. Leave it open and you'll get 30 seconds of warm water during a shower. Too much cold bypass water.

Thanks for feedback, I had managed to figure it out and yes, Valve #1 needed to be open.

Thanks for the tip on looking for the one on the side that feeds the boiler, that's the one I couldn't find. Didn't matter because when I helped them winterize, we used antifreeze in the boiler, and he will continue to do so just to be safe...it gets really cold here in the winter and I had heard that Alde suggests using Antifreeze in the boiler jacket.

All set, thanks again folks.
