Question about Water Heaters
Gas in system but will not flow into combustion chamber or the igniter
1) Gas control valve might be bad.
2) Copy following link to identify gas control valve:http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent
3) Link above has general troubleshoot information concerning each gas control.
4) If FV system tripped due to clogged air intake, then can shut down gas control.
Less air means slowed venting, but same amount of gas is still burning, which overheats combustion chamber tripping FV system.
Each brand is different: Some air intakes are located on bottom of heater, while other brands, the air intake is located under combustion chamber.
5) Gas control will also fail if thermostat fails and allows tank temperature to reach beyond ECO set point. The ECO is 1-time-use thermal fuse. Replace gas control.

What type of heater is this? I need to know the model name and make and then we can go threw the process of how to do it. Most gas heaters do not have power to them and I only know of a few tankless heaters that do.

The manual says to hold a match near the pilot while the ignitor is
trying. It says that if the unit lights the pilot orifice may be dirty
or clogged. Then the manual says to check
the voltage on the igniter. It should be 1.3 volts DC minimum if it is not means the electronic control box is defective.
Let me know the status ...Kevin

combi or standard if combi pressure too high and will be blowing off your high pressure release valve which would stop your boiler from igniting best of luck

You won't see any red glow until the burner ignites and burns for a while. Its only an ignitor and flame sensor, not a glow plug style.The ignitor has to provide spark for gas to ignite, then it also senses the flame and keeps gas flow coming. What exactly is happening when you turn it to on?

I have the RTG-53DVN, it too is an overly sensitive peice of ****. It worked for about 2 years, then started throwing errors. Had a plumber come out to look at it. He spent a lot of time on the phone on hold with Rheem, then they finally just overnighted a new circuit board. Well, that worked for about 3 weeks and now I have a brand new error code. What a peice of dung. Save yourself the frustration and do not buy a rheem.
