SOURCE: I need the basics for replacing a thermostat on a water heater...Bradford/White brand, model M250S6DS2 50 Gal, 4500 watt per element 240 voltage 50/60 hz. It keeps over heating even at lowest setting

Copy following link for replacing thermostat.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
Suggest you might also want to test the elements while power is turned off, just in case the problem is element shorted to ground across metal tank to ground wire.

At least you know the 240volt power to water heater and the circuit breaker are good.

How do I light my hot water heater?


It is pretty easy - make sure gas valve is open, change control know to pilot. Press the ignitor a few times and once pilot lights up switch control to warm or hot position.

Rheem 300170 HWS service manual


1) Rheem does not post service manuals.
Call Rheem and ask why, since the other big manufacturers, AO Smith and Bradford White do post service manuals.

2) You need new propane gas control valve, and matching combustion parts to fit existing tank.
http://waterheatertimer.org/pdf/Rheem-Water-Heater-parts-catalog.pdf
http://waterheatertimer.org/images/IMG_1826-LP-burner-450.jpg

3) Rheem does not recommend changing gas type, especially from natural gas to LPG.
LPG is higher pressure, and burns much hotter and requires cast iron burner, unlike the lighter-weight metal used for Natural gas burner.
The manifold tube and thermocouple must match the gas control valve, and gas-type and have correct thread for propane.
The combustion chamber and heat transfer surface can also be heavier metal for propane heaters.

I am thinking of purchasing a Reliance water heater and notice that there are many complaints about pilots continually going out. Have these issues been addressed? I currently have a A.O. Smith which has...


I do water heater research for specific purpose.
I see complaints about every brand except the brands that are no longer in business
Most complaints about gas heaters involve burners & pilot.
Here are some things that might help you decide:

New water heaters have to meet regulations
for clean-burning and efficiency.
As a result, water heaters exposed to poor incoming air supply, and poor venting are more likely to be affected by chronic pilot light problems.

Bradford White manual I was reading said, to remove chemicals from same room as water heater. Chemicals corrode water heater parts. This would affect the pilot light as well.
'Spray propellants, cleaning solvents, refrigerants, swimming pool chemicals, calcium and sodium chloride, household bleach, waxes and process chemicals are corrosive at very low levels with no odor."

Yearly maintenance: you're supposed to clean burner and combustion area with a wire bush and vacuum each year.

The FVIR is another consideration today. Flammable Vapor prevention.
Consult the manual before buying the product.
Many gas water heaters have a screen located on bottom of water heater. When the screen clogs with dust, the reduced airflow will stop the burner. Unless the water heater legs are set on bricks, then you can't get under to clean the screen.
If the FVIR trips because it detected a flash-over condition, you have to buy parts for all water heaters except the Bradford White. BW has a re-settable FVIR.

Maintaining your water heater is important.
Look for a brass drain valve instead of plastic.
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

Anode rod.
If water heater has two anode rods, the tank will last longer.
Inspect anode rod every 3 years.
Loosen anode rod before installing tank so it will come out easily for inspection
Or if it has a powered anode rod, it will supposedly last 'forever' ... until the burner gives out.

Bradford White hot water heater - burner lights only 30 seconds


The slightly warm water makes me think of a thermostat problem. The fact that the heater is 10 years old I wonder how hard your water is. Calcium build up kills water heaters. But the yellow flame you mention could be the results of dirty orfices. May want to have a Pro look at that.
