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.

Check gas pressure.

Replace gas control valve:

What's your problem?Power vent starts, unit will not fire up. Red light on board flashes steady.


Water heater and type of gas valve are not identified.
Add a comment and describe the 'board' you are talking about, and include brand and model number of water heater shown on label on side of tank for possible identification.
If this is a boiler or commercial water heater, then repost question for another expert.

First step for residential water heater is to identify gas valve to download error codes, and possible service manual.

For power vent water heater with Honeywell gas valve: three flashes indicate pressure switch or blower temperature switch not working.
Typical causes appear on page 13 on manual: can be bad blower, bad switch, blocked vent, exhaust temperature too high.

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.

I have an A. O. Smith Model FPSH 40-261 hot water heater. It won't heat water. there is a green light on the control flashing. What does it mean?


AO Smith uses the Honeywell ICON gas valve with green indicator light.
Some models use White Rodgers Intellivent with a row of indicator lights.

The gas control blinks the error code:

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.

Open following link for White Rodgers intelli-vent gas valve thermostat:
http://waterheatertimer.org/pdf/Intelli-vent-gas-valve2.pdf
http://waterheatertimer.org/How-to-adjust-water-heater-temperature.html#Intellivent

1) Typical instructions for Kenmore and AO Smith water heater with Intelli-vent say:
Set on-off switch to ON position.
Hold down both arrow buttons for 1 second.
Then press hotter button.

2) Also check that 120Volt electrical outlet has power, and check outlet with cheap circuit analyzer from home center.
3) If Intelli-vent gas valve thermostat is malfunctioning, and won't reset, then contact manufacturer of water heater for replacement gas valve.
Label on side of tank will have Model number, manufacturer, type of gas LP NG, serial number for part ordering.
