2018 Interstate water heater

[John1048]

I see that the 2018 Interstate has gone to a Suburban tank less water heater. Can someone tell me if this is the Suburban 5132A IW60 model that I see on youtube? If I understand correctly this is gas fired only -- no electric. And it seems to be controlled through the centralized systems control screen.
I am taking delivery of a used 2018 next week. Is there anything to check during the inspection other than continuous hot water at the taps in bath and galley?

Thanks for any help you can provide,
John1048

JOHN1048 - I have a 2018 with IWS60 5186. LPG direct spark ignition, no pilot, controlled via any of the 3 FireFly panels. There is an optional controller that prior owner could've also installed (my plan this winter) but that would've been installed post-delivery. I do not know anyone who has it in an AI yet. It should've come from factory preset at 120°F but mine came preset at 130° which actually makes it harder to fine control temp from super-hot to cold. That is switches D3/D4 inside control panel. OFF/OFF = 120° , OFF/ON = 130°. FYI - though LPG, its controller needs +12v to work via FireFly.
