Richmond powervent model 6G40PV-40F Lockout 4-2 blink. What's wrong. What do I replace to fix?


1) Rheem-Richmond does not post service manuals:
Copy following link to identify service manual by type of gas control valve:
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent

2) For lockout, the air intake might be clogged or combustion parts dirty, causing overheating which will break TRD glass vial. Gas control may need to be replaced. Reset gas control by rotating knob to lowest temp for at least 6 seconds.

3) Call Rheem or local service tech.

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:

Detecting gas and won't light


Open following link for troubleshoot error codes showing 7 flashes on Honeywell gas control valve is system lockout due to flammable vapor:
http://waterheatertimer.org/pdf/Honeywell-gas-control_error-Damper-series.pdf
The FV system in Rheem can be tripped by presence of flammable vapors such as gasoline or paint fumes etc, or it can be tripped if water heater was dropped, or mis-manufactured, or if gas control valve is defective, or if water heater is not getting adequate fresh air, or there is inadequate venting of combustion by-product.
When combustion chamber overheats, then glass vial breaks and damper shuts off air supply to water heater and it will not light.

Before calling service technician, read manual for troubleshooting and yearly maintenance requirements.
Open following links to identify same-similar product and download manual.
Once you have product showing on page, click 'specs-docs' tab to see use-and-care manual.

http://globalimageserver.com/fetchDocument.aspx?id=c0471d58-5e59-4be6-96f7-68361b8fb515
Rheem site loads slow, and some manuals never load.
Typical power vent manual:
http://waterheatertimer.org/pdf/Rheem-power-vent-manual.pdf

I believe the 21VP is older and Rheem does not show older manuals, but manuals are generally generic enough to help greatly. Year of manufacture show as second and third digit of serial number.

Lockout condition requires service technician and part replacement, or call Rheem and have them send part.
I found one link that talks about FV lockout that may or may not pertain to your issue:
