Why is the right side of the heater flame higher and hotter then the left side

Combustion needs air mix in the correct proportion to burn efficiently-also gas supply may be stronger on the outlet side of burner causing an imbalance-chech for obstruction in either area-cheers Denny

Proper install on forced vent AO smith ware tank.Need install directions for proper install.I think my plumber may have been wrong.In 10 years I have gone thru one tank and I am on my 3rd.blower...

It seems like something is wrong with the heater install, I have seen issues surface multiple times in years but I always dig deeper to find the real source of the problem (which is what you are doing! So glad). Here is a spec sheet (real basic info). Here is the full catalog (Install manual, operating manual, and service manual). This is for GDV/GDVT models, check your model, most piping diagrams for AO Smith are the same sizes. Here is the website for AO Smith residential that you can walk through: AO Smith website
Hope this helps you resolve the issue James

The combustion fan commonly known in the HVAC world as the Draft Inducer has a tube between the fan and the proving switch. The SUCTION from the fan is what causes the switch to trip and verify to the main board the inducer is up and going. Take that rubber hose off and check for obstructions between the two components.

My three year old has played around with the buttons and there is a key symbol and i can't get heater to turn on

Here is a link to the manual. See top of page 11.

Basically plug in the power supply. Before you even try to turn it on press and hold in the lock button for two seconds. What has likely happened is that the lock was enabled and then the unit turned off. You need to unlock it before turning it back on.

How do you turn off the child lock on a RinnaiRCE229H natural gas Heater?

Basically hold in the child lock button for two seconds. If the child lock was activated and you then turned the unit offt the child lock remains set and will stop you turning the unit on. To deactivate, make sure you have the power lead pluggeed in and turned on. Before you depress the ON/OFFbutton, hold in the child lock button for two seconds. This will deactivate the child lock and allow you to turn the heater on.

Here is a link to a users manual, check out page 11.

FV sensor went out when ainting the basement floor. The fumes burned out the sensor, purchased a new sensor, went to install and nothing happens. AO Smith water heater pro/Max

I find that most times when people think something is wrong and "FIX" it "BUT" it doesn't help, that just wasn't the correct diagnosis.
You may do better to look inside your info. that came with your W/H or call the company directly.
You didn't say how old it is. In some cases if the W/H is less than 1 year old they will repair it at no cost.
Hope This Helps;

Power usage

Hi YiXin

It will only use 2400 watts when on full. On settings lower than full, you will reduce the heat generated, and thus use less power. The amount of watts(energy) used is directly proportional to the heat the unit puts out. Hope this helps. A FixYa rating would be great for my solution. Thanks for using FixYa. Stay cosy :)
