Modern gas water heaters use a sealed flame arrestor chamber for the
burner.
This was mandated for those who put the WH in a garage where there may be
flamable vapors.

The flame arrestor is usually implemented as a honeycomb like vent panel
under
the burner. Unfortunately, the very reason that this was implemented
(garage
location) makes the solution a PITA as garages tend to be dusty and
dirty. The
dirt quickly blocks the honeycomb vent and the oxygen sensor for the
burner
shuts the flame down.

Clean the honeycomb vent and see if your problem goes away.




She said the water heater is new, so it should not be dirty yet.

OTOH, I just realized there is something fishy about this story...
I don't think they even make water heaters with pilot lights any more.

They do. It's a Bradford White. Not new but not old. This was installed 2
years ago.
