Answers:
Most residential AO Smith's have two heating elements controlled by thermostats.
A few will have just one, but they are not as common in my area.
Remove the front access plates with a philips or nut driver, which ever is needed.
Remove the Styrofoam cover. Some will still have fiberglass cover that you can remove.
If you have just one element, most of them will still have two access plates.
In heaters with one heating system, only the lower plate will have an thermostat and element behind it.
You'll see a little white knob that can be turned by a regular small screwdriver. I do this all the time and usually use my thumbnail, but I'm a pro at this too, so be alert regardless how you do it.
You are working around 220 volt, so leave the little plastic guard cover in place. Stay alert.
If you turn it up to 'c', you'll have lots of hot water, but the recommended setting is 'b', which is supposed to be 125 degrees.
If you do have a heater with two thermostats, turn them both up the same.
Since you have a new heater, the instructions to do all this is in the little book that is taped to the side of the heater.
That should do you.
BTW, AO Smith acquired State Industries, which made the better heater.
If they are making the heaters the way State makes them, it'll last you 15 years average.
AO Smith, State, Reliance, and presently, Sears are all the same. I'm sure they make others also that have different name tags on them.
I've alway's been an advocate of State Industries.
Their heaters will outlast American's, Rheem's, and Bradford Whites' by years and years.
There is a dial on the front of the tank close to the floor. All you have to do is turn the dial clock wise . Being it's summer I just set mine to a lower setting. Good luck
I think the heaters come preset to 100 degrees--the company does not want to be responsible for a water burn. Like McDonalds coffee burn a few years ago. Mine is at 120 cause when the grand kids come over and if they turn on the wrong fauset they will not be scalded. I never use hot water to wash clothes or sheets.. Powerful liquid detergents kill the germs. Costs too much to heat water---60% of your electric bill is hot water tank. The higher the temp the more it costs to heat water. Their is one or two panels on the side of the tank. Remove the screw and remove the panel. A temperature gage is will be their---put on your glasses---and set the temp to what you want--needs a screw driver.to move the temp arrow. Put the panel back on and do the other and match settings.
Read the directions. They're printed on the heater.
