I guess that it is a no brainer. Unless you are an experienced camper and then you just listen to the orientation and learn what's new. Froze my Furrion tankless heater because of it. Coming from a tanked heater and being told we have a tankless heater in our Reflection 5er you would think that a normal piping flush would work. WRONG. The tankless has a drain that does not drain with the rest of the piping. Our new trailer has an idiot board for the plumbing with brightly colord knobs with charts that show you how to do everything. Winterizing is one task. Place valves in correct position and flush. NO. Read the book. The red knob on the board bypasses the heater. Why would you bypass a tankless heater. Beats me. Read the book and in the details that no one reads it states that so it does and I did. No antifreeze in the water heater, the tankless heater. Though I did manage to get some in it somehow to save most of it. Unfortunately there is a low drain pipe that is not in the stream. If you read the book in the fine print it tells you as part of long term storage to open this drain. Not in the winterizing. Grand Design nor my dealer would stand behind the replacement; $1100. Was it my fault, yes but I think that Grand design also shares some responsibility. Our dealer did not know about the little red knob and found out accidentally. So I say don't trust the reps during the orientation. If you are new to tankless water heaters read the book.
