How to Reset Honeywell WV4464b1037
Flammable Vapor Sensor Lockout
- Reset control using ON/OFF switch on the gas control.
If the temperature of the water exceed 189°F (87°C)
- The gas control valve pictured in this manual is equipped with a resettable type automatic high temperature cut-off. Should the temperature of the water exceed 189°F (87°C), the high temperature cutoff will automatically shut off the gas supply to the water heater. If this situation occurs, the gas control valve must be reset by a qualified service technician.

Please read carefully!
This water heater is equipped with a flammable vapour sensor (FV) that will shut it down in the event of a flammable vapour incident. It is a safety feature that may prevent property damage, personal injury, or death.
The FV sensor is located on the front left bottom of the exterior casing of the water heater. The FV sensor is protected from shock and contaminants by a robust plastic cover. The function of the FV sensor is to detect the presence of flammable vapours before they enter the combustion chamber and ignite. If the FV sensor detects the presence of flammable vapours while the water heater is operating, the gas control will switch to lock-out mode and the water heater will shut down. If the water heater is not operating when the flammable vapours are detected, the control will switch to lock-out mode and prevent the water heater from lighting.
After a flammable vapour incident has occurred and the flammable vapours have dissipated, the FV sensor is designed to automatically reset itself. The Intelli-Vent™ gas control however, will have gone into lock-out mode and will need to be manually reset. A qualified service technician must be called to determine if flammable vapours entered the combustion chamber and ignited. In most instances, there will not have been ignition of flammable vapours inside the combustion chamber because the FV sensor will have detected these vapours and shut down the water heater. In this case, the Intelli-Vent™ gas control can be reset and the water heater may resume normal operation. On the other hand, if the flammable vapours ignited inside the combustion chamber, the water heater may need to be replaced. The technician will be able to determine whether or not the water heater needs to be replaced based on the amount of flammable vapours that entered the combustion chamber and the damage to the water heater from the resulting fire.
Generally Reset
for Gas Control
Is your water heater showing a flammable vapor sensor code?
Luckily that error code can easily be reset and you will have hot water again in less then an hour. The reset procedure will vary depending on which gas valve you have. Before resetting the flammable vapor sensor, make sure there are no flammable vapors or containers near the water heater.
Here are the different gas valves and how to reset them:
Honeywell Gas Valve:
1. Reset the control by unplugging the blower, leave unplugged for at least 5 seconds.
2. plug back in and within 30 seconds cycle temp control from hot to low 6 times.
Rheem Water Heater with a White Rodgers Gas Valve:
1. Reset power to the water heater and tum the unit on. The FV error code will re-appear. Within 30 seconds…
2. Press and hold left and right arrow keys on the control valve at the same time, until the green light begins to blink.
3. Press left and right temperature adjustment keys in the following sequence: Left Right Left, Left, Right Left Right, Right.
4. If the error code is reset, all the lights will come on. The valve is now reset.
Intelli-Vent Gas Valve:
1. Reset is accomplished by first, turning off power to the water heater for 10 seconds.
2. Restore power to the water heater.
3. Within 10 seconds of restoring power, press the two temperature adjust buttons simultaneously until the left (green) “Vacation” LED begins to blink (approx. 5 second delay). Once the Vacation LED begins to blink, release both buttons.
4. Again, within 10 seconds, press both temperature adjust buttons simultaneously until the Vacation LED is on steady (approx. 5 second delay).
5. Release the two buttons, the microcomputer will clear the FVS lock-out and normal operation will then be restored.
Robertshaw Gas Valve:
1. Turn the manual lever on the Control Gas Valve counter clockwise until it snaps to the “on” position.
2. Keep the temperature dial on Vacation.
3. Plug in the power cord and turn on blower switch and wait 3 seconds for the system self-diagnostic check.
4. Within the first 30 seconds, the temperature dial must be rotated back and forth crossing the 120° F mark at least six times. ( You can do this by rotating the red dial from Vacation to Hot to Vacation….)
5. This will reset the Control Gas Valve and cause it to display a normal flash code for the LED on the left bottom of the Control Gas Valve. Note: Slow blinking is the normal flash code.
