Rheem FVIR or FV or TRD combustion shut-offs are meant to be reset/replaced by trained service technician.
I asked your question at the Tank forum a while back, and the pros there would not say how to do it, citing liability concerns. They were offended when I kept insisting on an answer, but nobody came forward.
I found a link with interesting information:
http://www.diychatroom.com/f7/rheem-hot-water-heater-pilot-burner-not-staying-lit-65755/
Quote from link above: ""Called Rheem. They are now supplying a replacemnt TRD kit, part number SP20246A. ... $0.25 glass part...Said you're supposed to have a "certified tech" install it. But since I had the thing apart 4 times already I did it myself in about 5 minutes. Easier than changing sparks plugs. Now, the thing broke again. Bypassed it with a small binder clip for now."" end quote.

I have personally searched Rheem website, and have not yet found service bulletin for FV or TRD replacement, or a guild for part number by model number.
If my research pulls up complete answer, I will try to post additional information to this thread

If have only seen this happen a few times, first, i save the part from old water heaters that i replace, so i always have a couple . Second , the vent at the bottom could be parcially blocked from dust so you dont have proper air flow (blow it out with air). Third the heater could be over heating and creating too much heat near the burner.
Good luck

When the glass tube breaks is has done so because the screen under neath the burner is pluged and can not let the air into the burner. Which causes the flame to look for air or go to the limited air sorce. You must blow out the screen ad vacume it to remove any dust, lint and hair build up. Slos the sides were the larger holes are needs to be done too. If you dont it will quickly break the glass tube again and then they will not send you another one as only one maybe 2 per customer and you will have to buy a new water heater.
Sending to the home owner is there way to keep track of what water heater is breaking the glass tube and if not cleaned or it does it again they can sell another water heater but hopfully the home owner will by a diff. brand that does not have this type of safty.

You are playing a risky game with a gas appliance. Those saftey features are made from hazard situatiars that were found out and learned the hard way. You take a big gamble with yours and your families lives by bypassing the saftey feature on a gas water heater. Best of luck to those who care to take such a gamble.

SOURCE: where is the combustion shutoff system on a Rheem 30 gal moble home hot water heater

Disproportionate number of water heater problems are Rheem-related, yet Rheem is just 1 of 3 major water heater manufacturers.

If you have Rheem tank-type gas water heater, and the combustion shut off has tripped the FV system, then there is a broken glass vial located under the burner.
Rheem does not post service manuals, and they may or may not send the glass vial for replacement. Depending on model which appears on label on side of tank. Year of manufacture are 3rd and 4th digits in serial number.
And they may want you to contact a qualified service technician (plumber)
You will have to replace glass vial, and clean the arrestor screen and clean the combustion parts, check gas pressure, and check venting.
Other companies post service manuals and do not rely on the glass vial.

I have a GE Smart Shield sensor system hot water heater and it will only let a small amount of water in at onetime


GE is made by Rheem ... and the heater has a thermal device located inside combustion chamber that trips when heat inside combustion chamber exceeds approximately 180°F. Tripping off can be caused by ignition of flammable vapors or by malfunction of vent, incoming air supply, dirty combustion parts, or failed thermostat on gas control valve.

How to test flammable vapor sensor lockout on whirlpool gas water heatermodel nd50t122-403


You could clog up the screen on bottom of water heater... and this would cause FV system to trip because of overheated combustion chamber... then clean arrestor screen and push reset button located on front of combustion chamber to get water heater working. Of course you might have to replace parts to restore functionality.
Or pour some gasoline nearby and see if the water heater explodes, or if the FV trips. I would think this to be unwise.

Pilot light wont stay on


If the thermocouple is OK, the combustion air vents may need to be cleaned. Otherwise, the combustion shutoff device has probably tripped which will need to be replaced.

My 50 gal lp water heater made a slight boom sound and now when i lite it and turn on the main bunner it snuffs its self out


1) Call manufacturer with model number and serial number appearing on label on side of water heater.
http://waterheatertimer.org/Water-heater-manufacturers.html

2) Copy following link to troubleshoot by type of gas control valve:
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent
http://waterheatertimer.org/How-to-replace-thermocouple.html

3) Product manuals today recommend yearly service, and yearly cleaning of combustion parts, and to keep air intake clean.
If air intake becomes clogged, or combustion parts get dirty, it can slow the exit of combustion gasses, and this will soot the burner, and clog burner ports, which means slow lazy yellow flame and incomplete burning of released gas. So unburned gas is present in combustion chamber and up the flueway. The ignition of unburned gas can cause explosion of various intensity ... and the 'boom' sound you heard.

The explosion certainly overheated combustion chamber and tripped FVIR system.

4) Since each manufacturer has different FV system (flammable vapor ignition retardation system), and each manufacturer has continued to make changes over time in FV systems, the solution for tripped FV will vary by brand and age and model of water heater.
For example the intellivent gas control can be reset in some models, while other models require replacement of parts ranging from gas control valve to FV sensor to glass vial, and include possibly full replacement of water heater.

How to take off the thermal couple off a ge sg40t12txk


1) Copy following links:
http://waterheatertimer.org/How-to-replace-thermocouple.html
http://waterheatertimer.org/How-to-repair-Rheem-TRD.html

2) GE is made by Rheem, so air intake screen is located below the combustion burner, as is the TRD (thermal reset device).

3) Modern gas water heaters, the FVIR, or FV system will trip when air intake gets clogged with dust.
This will slow venting of hot combustion gasses, except burner is still burning same amount of fuel. Overheating occurs, and that trips FV system.
Other brands require cleaning air intake screen and possible replacement of gas control valve, or FV sensor, etc. Each model is different.
Rheem_GE overheating will trip TRD, and glass vial breaks, causing air intake to close. Glass vial must be replaced, and possibly the gas control valve replaced.

Gas not getting to the combustion chamber of water heater


1) Gas control valve might be bad.
http://waterheatertimer.org/pdf/How-to-replace-water-heater-gas-valve.pdf

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.
http://waterheatertimer.org/How-to-repair-Rheem-FVIR.html

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.

Put in gas valve, a few days later sensor set lock out due to flamible sensor setting off. what are the codes to unlock system?


Air intake is probably clogged, so combustion air flow slowed and caused overheating inside combustion chamber.
This tripped FV system and broke TRD, which is a small glass vial located under burner. The spring-activated air baffle snapped closed and shut off air supply, and also tripped FV lockout of gas control.
Remove burner, replace glass vial ordered from Richmond, and clean air intake.

If you have Intellivent gas control, then it can be reset.
