Gas Control Valve replacing!


Shut off the water and gas to the heater. Drain the heater. Disassemble the gas line to the heater starting at the Union and working to the gas control. Disconnect thermocouple, burner and pilot tunes from the bottom of the old gas control. The old control will screw out of the front of the heater. Grab the entire housing of the control and twist counterclockwise to remove. Perform new gas control install and connections in reverse. Remember to apply at least 4 wraps of Teflon tape on all threads before assembly. (Teflon paste may be used) Do NOT put any sealant on the thermocouple,burner tube or pilot tube connections (these are compression connections, make them fairly snug.) upon completion, fill heater, turn gas back on relite and check for water or gas leaks

Rheem Intelli-vent intermittently goes in lockout mode


Rheem does not post service manuals.
However AO Smith has posted relevant service manual:
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent

Have you cleaned the air intake located under combustion chamber, and inspected for broken glass vial?
Rheem FVIR system uses glass vial that breaks if combustion air is slowed, and resulting combustion causes slow-moving venting of hot gasses, causing overheating that breaks glass vial.
http://waterheatertimer.org/How-to-repair-Rheem-FVIR.html

Check gas pressure.

Replace gas control valve:

Water heater pilot light is out, cant restart intelli vent controller


Possibly the air intake located at bottom of heater needs to be cleaned with feather duster under water heater.
Read your product manual for steps.
Copy following link for general illustration.

http://waterheatertimer.org/pdf/Flame-Arrestor-Screen-Cleaning.pdf
Other causes can be bad intellivent gas control valve, poor venting, hot attic, low gas pressure, dirty combustion parts, tripped FV system.
Copy following link for available intellivent troubleshoot resources:
The service manuals are large files and open slowly.

Intellivent gas valve shows AB and vacation error lights:

The igniter and flame sensor have to be positioned correctly:

Check electrical outlet with circuit analyzer, and test that unit is receiving 110Volts
Intellivent gas control must be grounded.
Check that gas control is getting 24volts.
Check for air in gas line and low gas pressure.

Is there a reset button for a 6G50NVH-FV-02 hot water heater


Depends on gas control valve, and if cause is overheating high-limit event or FVIR flammable vapor event.
Turn off water heater when using flammable vapors, clean burner parts to prevent overheating.

1) GSW Residential power vent gas water heater with FVIR system:
Some models have intelli-vent gas contol
Others have robershaw gas control with auto-reset

2) Parts manual shows #15 'auto-reset' high limit switch on the blower
http://www.gswpartsonline.com/model/27484
http://www.gswpartsonline.com/schematic/137/view

3) Possible manual:
http://www.gsw-wh.com/pdfs/GPD135NInstall.pdf
Shows resettable lockout page 15
Water temperature must be 120 degree F or lower for reset. Unplug power cord, and then plug back in and wait 15 minutes or 60 minutes depending on gas control valve.
Some intelli-vent controls must be replaced when 195 degree high limit event locks out the water heater.
If high-limit lockout repeats, then gas control must be replaced.
Also clean burner parts, air intake, and make sure flame is clear blue. and not yellow-or-orange.

4) Intelli-vent service manual might apply to your water heater:
http://waterheatertimer.org/pdf/Intellivent-service-manual.pdf

If FVIR flammable vapor event locked out heater, then unplug heater and plug back in.
Immediately press two temperature buttons. Wait for green light to blink. Release buttons.

Most gas water heater problems today can be solved with yearly maintenance that includes cleaning burner parts, clean air intake, check venting, check electrical connections, bleed gas line, and check gas pressure.
Gas water heater manuals recommend yearly maintenance by service technician.

In past years, gas water heaters required less maintenance, but they were less energy efficient and more dangerous to operate.

Sounds like you have Intellivent gas control valve thermostat.
Open following link to identify gas valve and see error codes:
http://waterheatertimer.org/pdf/Intelli-vent-gas-valve2.pdf
http://waterheatertimer.org/How-to-adjust-temperature-on-water-heater.html#intelli

Error light on vacation + 2 other lights = 3 possible conditions:
1) Wiring error: check outlet with circuit analyzer:
http://waterheatertimer.org/images/Typical-circuit-analyzer-15.jpg
2) Pressure switch tubing not connected, air intake obstructed (clean intake), or vent exhaust obstructed (check for proper venting).
http://waterheatertimer.org/images/Test-water-heater-vent-400.jpg
3) System in lockout: Low gas pressure, hot surface igniter not positioned correctly.

You can do some of this yourself.

Hello Mike,
Check gas pressure, burner parts need to be cleaned, check electrical outlet, hot surface igniter is bad

White Rodgers intellivent error code:
http://waterheatertimer.org/How-to-adjust-water-heater-temperature.html#Intellivent
http://waterheatertimer.org/pdf/Intelli-vent-gas-valve2.pdf

Error code says: system in lockout, but you know that.
1) Low gas pressure, no gas to water heater: call gas company to check pressure
2) Hot surface igniter not positioned correctly: inspect and clean burner parts.
http://waterheatertimer.org/images/Reliance-hot-surface-ignite.jpg
3) Low voltage to water heater/ outlet has wrong polarity: Use circuit analyzer on electrical outlet to make sure polarity is correct
