@minrk OK I have to know
is it a detented dial, ie does it click into the different settings or can you slide it between so you can have half of C and half B?
Sadly, it's pretty common. Last two water heaters I've had were like that.
All I can think is that it's less "what temperature do you want?" and more "How often do you want the burner to run?" since I guess they're too cheap to put a thermocouple near the top of the tank.
FWIW, I think they also screwed up the labeling. " " should be "Low" and "Low" should be something like "Vacation".
Yes, but what if it went to eleven?!?
@minrk
I think that's finally even worse than the electric one what I deal with. I could put my thumb in the image for scale but it would cover the whole "dial". You use a miniature screwdriver to adjust it.
Last time I adjusted it my wife asked "what's it set at now" and I'm like "i dunno, somewhere between 120 and 150. She's like "no seriously, tell me " so I took the cover off and showed her and her response "that's the dumbest thing I've ever seen, why would they do that"
Set it to "square." It will reach "purple" in about 40 minutes and then double that. Bob's your uncle.
@minrk Mine has roughly the same scale. I have found "A" to be pretty good, but YMMV.

@minrk @brainwane Must be from the same people who made the fuel gauge in my car, which has 12 at the top and 7 at the halfway mark. The needle sits above the top (12) mark for about half a tank and then drops rapidly.
I use the trip counter (reset when filled up) to estimate when I need to fill up again :)
