I've got a one year old Rheem water heater. Apparently, there is a
problem involving the amount of air that is entering the sealed
combustion chamber. There is sufficient natural gas pressure. No
problems with the thermostat, that has been replaced TWICE. The entire
burner assembly has been replaced and the system is venting properly.
Yet the flame, an orange one, never gets as hot as it should. Since it
is a sealed combustion chamber, there is no way to adjust the intake
of air. The inlets are not blocked, clogged, or otherwise. The heater
is in an open basement, with two feet of open space surrounding it.
Two customer service reps at Rheem say that the combustion shutoff
device is likely tripped, and if that's the case, the only way to
remedy the problem is to replace the unit because the tripped device
can not be replaced or repaired. The manager of the technical
department says that if the device were tripped, there would be no
flame at all. What else could be wrong?

Just one thought:
Quote: "There is sufficient natural gas pressure"
But has the output pressure of the regulator
in the control been measured?

I had a water heater with flame problems. Found the center flue through the
tank crushed. Not much, but enough that the flame was screwed up. Problem
was caused by my water pressure regulator not allowing water to back up into
the main. Pressure was excessive. After trying to figure out what was wrong
I noticed water dripping from the pipe on the pressure relief outside right
after a shower. Figured the pressure had to be very high. Then I removed the
flue pipe and tried to pull the twisted metal heat spreader out. It was
loose but I could not pull it out. Looked down the center of the tank and
saw the problem. Tank was about five years old. I added an expansion tank
and that solved the problem.
