My water heater is fussy about staying lit on windy days.

Do you see 1, 2 or 3 valves behind your water heater???
And to answer your question, no they are not supposed
to be all open. The valve that actually does the bypass
should be shut. (This will be the valve that goes
between the cold inlet and the hot outlet.)
The remaining valve(s) should be open for normal
