Tankless water

[Kopy kat]

I can’t find detailed directions in the keystone manual for preparing the suburban tankless heater for winter...I’m used to pulling the anode rod out and draining the tank model, but not sure what I need to do with this one.

Is it just as simple as filling the tankless coils with antifreeze?

Maybe I just need to move south...

You won't find that in the Keystone manual. Look in the paperwork that came with the water heater or on the suburban website.

Seems so. Drain and antifreeze.
