I'm not sure this was posted anywhere else, if so I apologize.
I have been in touch with GD and Furrion on use below 39 deg and above 4500' and have a response. The freeze protection retrofit is a new control board that is suppose to offer freeze protection. The email I received is below. I called and found out the cost is $103.95. I asked for specifics which those I spoke to did not know. I replied to the email asking specifics of how it works or what it does to keep it freeze protected and to now what temps it is rated.
EMAIL response from Furrion
For the elevation you may expect a derating at elevations above 4,500ft and you can use the knob on the unit to adjust flow rate down so that the water comes through the unit at a slower rate and has more time to heat. We don't recommend use over 10,000ft. For use in temps below 39 degrees there is a control board with freeze protection to can purchase and replace your current one. You can order that part through Lippert using item number 2022006595. Their number is 574-537-8900.
My questions I have asked waiting on response:
Specific questions are what temp is it now rated to?
What actually does the board turn on to keep it freeze protected?
What is difficulty of installation?
Any other pertinent information?
I for one am happy with the altitude answer and solution. Have not tried yet but seems user friendly and planned for if it works. Just wish it was more clear in the manuals. GD response to this question was..well.. lacking quoting a section of the tank water heater. To me this was doom and gloom answer stating that the tankless would have to have orifices changed (derating). Furrion seems to have a better answer. And for what it is worth I was at higher elevations past summer and did not seem to have any issues with hot water (did not adjust the knob) although it was constantly in the 90's during the day so did not require extremely hot water. I am sure many have had similar experiences. I doubt I will ever be above 10k feet elevation for any length of time .
Will keep posting what I find out.
