This honeywell gas valve is getting a bad wrap online. I have installed over 1000 and have had bug with roughly i in 120 units installed. The reason people are having then many issues with this gas valve is because the Regime now requires a lower threshold for backdrafting. So the units that are having problems are about probable installed in improper environments. These tanks pictured below show signs of backdrafting.

One quick tip on the installation. The vent should have at least 12″ of ascent before the first elbow. The maximum horizontal span for 3″ vent pipe is 48″. If the unit is common vented, with a connector rise of less than 3′, the vent should almost likely be iv″, not 3″.

Gas valve by Honeywell

This gas valve is commonly used on AO Smith, State, Whirlpool, and Rheem water heaters. The LED indicator helps you troubleshoot the upshot by reporting a number of flashes.

No Wink = Pilot non lit, non enough power.

i Wink = Normal Operation
2 Flashs = Thermopile low voltage
iv Flashes = Temperature Exceeded
5 Flashes = Sensor Failure
7 Flashes = Gas Control Valve Failure
8 Flashes = Power off Failure

two – Replace Pilot Assembly Insufficient power to the gas control valve/thermostat. Check all wiring connections. If problem persist you will demand to supervene upon the thermopile. When replacing the thermopile you must supersede the entire airplane pilot assembly.

4 – Supervene upon Gas Valve If the temperature has exceeded the limit the gas valve will need to be replaced. Often blamed on sediment in the tank, the 4 flashes is ane of the most common problems with the Honeywell gas valve. In some cases it is recommended to keep the thermostat temperature downward to prevent exceeding the limit.

5 – Replace Gas ValveThis indicates a sensor failure and the gas command valve must be replaced.

7 – Replace Gas ValveOverall failure of the gas valve and will commonly require replacement. If you get this code and take lukewarm water and the airplane pilot is still on, try turning upwards the temperature. This has happened to us twice and both times has resolved the outcome.

8 – Reset Gas ValveThis will only appear afterward the gas valve has been shutoff and continues to produce a current to the thermopile. Plow the gas control dial to off and permit sit for one infinitesimal. If the pilot remains lit you will need to supersede the gas command valve.

Honeywell gas control valvecleaning the intake on a gas water heater

If y'all are having bug with your pilot in that location are a couple of steps you should consider before replacing the gas valve. The first is the air intake, water heater build afterward 2004 have a sealed combustion bedchamber and air is non equally easily drawn in equally older models. The air intake is located on the bottom or side of the water heater and may need to exist cleaned out in order for the pilot to stay lit.

If you don't come across a spark at all when you are trying to lite your pilot it may be that you are not looking in at the right bending. You have to put your ear downwardly to the flooring to see the pilot. If you accept the right bending and all the same don't see the flame it could exist the ignitor. Get-go try disconnecting the ignitor button through the removable disconnect. Pulling information technology apart and putting it dorsum together sometimes does the trick.

Testing the Gas Pressure on your Honeywell Gas Valve

This is a flick of a test to verify the gas valve had the proper working force per unit area. The manometer is set to PSI and standard pressure when pilot is .143 PSI when the gas burner is on.
