I have the same model, installed in 1994 when we built the house. I looked into this issue some time ago. The therm is fixed and not adjustable.

How to change out copper piping from release valve

If the release valve referred to is the pressure release valve, then a water leak out the attached vent pipe is an indication that the valve is failing. To change the valve, the water must be allowed to cool (turn off AC power or gas) and the water level inside the tank must be lowered (drained) to below the level of the pressure relief valve. Once this is accomplished the vent pipe is unscrewed from the relief valve and the pressure relief valve is unscrewed from the water tank. A new pressure relief valve with a sealant on the threads, is then screwed and tightened into place with the outlet port facing downward. The vent pipe is attached to the new valve and the tank refilled with water. A hot water facet must be opened to allow air to exit while filling. Upon becoming full (water will begin to flow from facet), turn off the facet and restore AC power or gas, therefore allowing the water heater to heat up. When the first hot water is utilized there may be some air expelled from the facet.

How do I get the hot water tank working . we just moved in to a new place... Never been lived in. Landlord is gone. Tank has never been used. Its a reem tank.

Would need to know the model number, gas or electric for starters.
If electric you just need to turn on the circuit breaker probably.
If gas is it direct vent, power vent or standing pilot, that is why a model nnumber comes in handy.

I have a John Wood one pipe power vented hot water heater. The model number is Jw840nvh-fv-04. Recently I've been smelling products of combustion coming out the top of the tank where the vent is.

If this heater is located in a "confined space", has the "make up air" entry point(s) been restricted/blocked? In short, is there enough air present to support combustion AND to supply enough air for the power vent to move the gases at a reasonable rate to the environment?

Can you "feel" the gases coming out the vent at a reasonable thrust? Is the power vent blower motor making any noises (not rotating properly, i.e., bad bearings)? Does the vent have any debris at the end, possibly at a screen?

Is the T&P valve dripping water? Is there ANY water on the floor? Is there a thermal blanket on the heater? Is the blanket wet anywhere? Did you recently add a thermal blanket? (Some manufacturers DO NOT recommend a blanket.) Have any liquids been spilled on top of the tank? Is anything dripping on the tank?

Is the burner flame crisp, not "lazy"?

"Recently I've been smelling products of combustion coming out the top of the tank where the vent is". There is a negative pressure present at the top of the tank where the vent is - in a properly drafting vent pipe assembly. This means that vapors, odors, and moisture ARE BEING SUCKED OUT of that area under and through the hood and then into the piping. "and when blew some smoke at the vent, it drafted up through the vent no problem". Try to identify the real source of the odor.

Lastly, I think this model uses a direct connection technique from the blower/power vent termination to the piping without a hood. So if you blew smoke at the vent, and there is no hood, how would the smoke get into the vent? If the 2" vent is PVC or CPVC, and if the gases are being slowed because of any reasons mentioned, maybe the plastic piping is slowly cooking.

No hot water. Constant beeping at the tank. Tempature gauge flashing 11.

Before calling service technician, open following links for Rheem troubleshoot resources including Rheem chat and typical service manual and typical product manual.

Error codes are start place for troubleshooting:
Error 11 is 'gas is inadequate' or 'ignition failure'
Open gas valve so handle is parallel with gas line.
Bleed air from gas lines.
Check that appliance is grounded.
Check igniter wires and harness for damage.
Check that vertical vent length does not exceed limit.
Other causes: Gas inlet solenoid valve, bad igniter, solenoid valve, flame rod.

Rheem power vent motor doesn't shut off

There could be blockage in your water heaters venting on the outside of the home. It sound like the high limit switch has been tripped. Try unplugging the tank and plugging it back in. this will reset the tank. if the problem persists you will want to call your provider for service.
