SOURCE: gas hot water tank, pilot light

Look inside the water heater when it is heating the water, the flame should be blue. If it has yellow tips on the flame, it needs an adjustment to the air shutter. There is a nut on this air shutter to make this adjustment. This adjusts the air gas mixture. You may first try just simply tapping on the burner lightly to loosen any debris that may have built up and vacuum it out. MAKE SURE YOU TURN OFF THE GAS BEFORE CLEANING THE BURNER!! Also, check for drafts that may be blowing out your pilot light, Furnace register or outside drafts on windy nights. Some water heaters have an automatic shut down if the water heater gets too hot, so don't have it set to its hottest setting. Most water heaters only last about 10 years or so, It could be you are ready for a new one....Joe

Most likely it's time to replace the thermocouple, the safety device that makes sure the pilot is lit. New thermocouples are cheap and you can find them at most hardware stores and the big-box places (Home Depot, etc.)

Here is a site with basic information to get you going.

SOURCE: Tankless water heater pilot light will not stay on

It is most likely the water valve stuck open, telling the controls to heat water, that it thinks is flowing through it, but without actual flow it overheats. Depending on how comfortable you are with taking it apart yourself, you could open the valve to see if it just needs cleaned out, or if you have a ruptured diaphragm or some other cause.

SOURCE: Rheem 40 gallon gas hot water heater, pilot light

To make a short story long (I need to include all details, sry)…

I got up one morning and realized that we did not have hot water. I re-lit the pilot light and as soon as the burner went out from heating the water up, the pilot light would go out. After reading several posts regarding this issue, it seemed apparent that the thermo-coupler was the problem. Since I am a little bit handy around the house and very tight when it comes to opening my wallet, I bought the device from Lowe’s ($8.98) that was recommended by my online advisors and after a few googles, figured out how to change it. No help. The pilot light still goes out.

I gave up and went to Home Depot to purchase and schedule the installation of a new hot water heater.

STICKER SHOCK

A new Direct Vent type water heater costs around $800 with an additional $450 for “special” installation. Add a few fees to that and the grand total came to about $1450.

I felt like I had no choice since my wife and 2 daughters refused to live their life without hot water and I had no clue about how to fix the dam thing.

The plumber assigned to the installation stopped by to evaluate the site conditions and quickly noted to me that the 8 year old water heater tank was in good condition and that the gas controller was probably faulty, which could be purchased online from the manufacturer. I quickly cancelled the Home Depot order and purchased the controller for about $120 after shipping and tax. Immediately after the installation it seemed that the problem had been solved. A few days later the pilot light went out.

I called the plumber and explained the situation and he recommended that I purchase another controller because the one that was shipped to me was probably bad. I searched around town and found a plumbing supply company that had the correct model in stock. Two days later the pilot light was out. I cleaned up the controller and returned it to the store and asked the plumber to please schedule a visit to repair this dam thing.

When the plumber arrived, he hooked up a gauge in several locations and confirmed that the correct amount of gas (cfm) was being delivered to the controller, pilot light and burner. He then proceeded to remove the fire box to make sure that the igniter, thermo-coupler and pilot tip were set properly. He inspected the pilot light tip and said that he found the problem. Using about a 1/64” tip drill (can be purchased at a welding supply store), he cleaned the tiny hole that releases gas to the pilot light. I felt a sigh of relief because I was certain that the problem had been solved. $65 dollars (plumber’s fee for an hour of work) and 4 days later the pilot light went out.

I called the plumber and he said that the controller that I purchased online must be bad. Too embarrassed to return to the first plumbing supply store, I found another one in a different town that had the correct model in stock. Three days after changing the controller the pilot light went out. I returned the controller and a six pack later I decided to do some extensive googling.

The key term here is “DIRECT VENT”. This seems to be a very common problem with direct vent water heaters and I was about to find out the reason for this phenomenon. I read a post by an individual who wrote that if the vent becomes detached that the inflow of air can become contaminated and extinguish the pilot light. I decided that before I spent any more money on a plumber that I was going to take the vent apart and find out what makes it tick.

My direct vent system has 2 parts to the venting, an inner pipe (3” nominal diameter) that serves as the exhaust and the outer pipe (5” nominal diameter) that serves as the internal flow of air which supplies the pilot light and burner with oxygen. On the outside of the house a vent hood helps to segregate the two by extending the exhaust about 3” beyond the intake. I looked into the hood at the end of the pipes and discovered that the internal pipe which consisted of a 2 piece slip joint had come loose from the elbow that sets on top of the water heater. This slip joint pipe was not attached at any point with screws or clamps and was loosely setting over the elbow on one end and into the hood on the other end, allowing it to detach. Apparently, when atmospheric conditions were right, the burner idled down from heating up the water and extinguished the pilot light because the intake was saturated with CO2 from the connection failure.

I purchased a section of 3” pipe that was long enough to be installed in one piece. I connected it to the elbow using a stainless steel hose clamp. I had to disassemble the pipe 3 times to make adjustments to the length and position before I got it right, but I should not have any more problems with the pilot light.

The problem here is time. It takes a lot of time to get this right. When the plumbing contractors installed this unit during the construction of the house, there was no one around to make sure that they got it right. It is probably common to use a 2 piece slip joint type connection, but I feel like it should be attached with screws or clamps. In my opinion it is not rigid enough and can detach easily, especially if it is not installed properly. A one piece connection that is attached at one end with a hose clamp and then held in place at the other end by the hood is fool proof.

SOURCE: pilot light on water heater wont stay lit

The thermocouple has failed. It is the temp probe that goes from the pilot lite burner area to the control valve. Go to your local plumbng repair shop and buy one. Most appliance parts stores have them also. Take the old one with you and they will hook you up with an exact replacement. They are not that hard to change. Usually a nut or 2 screws in the temp bulb area at the burner end and a nut that threads into the control valve.
Make sure before you install the new one that the area where it mates to the gas valve is clean. Should be about a 20 min job including clean up with replacement parts in hand.

Don't forget that gas supply to water heater has to be ON. Gas shut off valve must be parallel with gas line.

Why did water heater turn off?
If water heater was exposed to flammable vapors like gasoline, paint thinner, paint, leaking gas line, etc, then the 'single use gas shut off' might have tripped.
If water heater is older and the burner parts never cleaned, then combustion chamber can experience overheating, and that can trigger 'single use shut off.'

Instructions for lighting water heater should be printed on side of heater.
Follow the instructions and see if water heater will light.
Then check if flame is clear blue. If flame is yellow-orange, then burner parts need to be cleaned.
If water heater will not light, then combustion parts may need to be cleaned, and air intake cleaned, and 'single use shut off' could also be tripped.

Also possible that gas control valve thermostat is bad.

The problem requires looking at manual and service handbook, except handbook doesn't show most recent water heater.
My first check point would be gas supply, and then vent draft, and then air supply.
Take off front cover and try lighting again to make sure air supply is not problem.
Review lighting instructions.
If there is no gas, and gas is turned ON, then gas control valve is suspect.

Hot water heater pilot is off. It's not gas,


You have tank-type gas water heater:
Open following link to watch thermocouple replacement.
Make sure new thermocouple sits into pilot flame. Instructions for relighting water heater are usually printed on side of tank.
http://www.youtube.com/watch?v=v0aBPsNg6vo

Gas water heaters need working thermocouple, adequate incoming fresh combustion air with no trace amounts of chemical, open vent to outside that drafts poison combustion product upward, clean burner tubes and combustion parts, correct gas pressure with no air in line, working gas control valve thermostat, no lockout condition such as tripped ECO caused by runaway heating and dirty combustion parts, and no lockout condition such as exposure to flammable vapors.

Most gas water heater problems can be solved by having service technician perform yearly maintenance. Or by doing maintenance yourself.
This maintenance includes cleaning burner parts and combustion chamber, checking gas pressure and supply, bleeding air out of gas line, checking vent draft, making sure air supply is adequate and not exposed to chemicals, cleaning air intake. Also adjusting flame sensor so it is positioned correctly. If water heater is connected to electric circuit, the outlet must have correct polarity.

You can get gas to appliance indicates the gas control valve and water heater are not locked out. But the gas control valve thermostat can still be bad.

I have. A 40 gal. 40,0000 btu natural gas , how do u lite the pilot light


Access is at the bottom of the water heater. There is a little cover you will have to take off. Look for the gas valve. (its where the gas will come in to the water heater) Follow the two lines that come off he bottom of the valve. They will lead you to the burner (big line) and the pilot(smaller line). The pilot is what you are looking for.
1. locate the pilot (it will be 8" or so in to the water heater)(right next to the burner)
2. Turn knob on top of gas valve to "pilot"
3. Push down the knob on top of the valve that you just turned to "pilot" or there may be a lever right next to the knob on some models
4.with a long fireplace match or bar b que lighter, while holding the knob down, reach your lighter to the pilot assembly. you may smell a little gas.
5. The pilot will light, do not let go of the knob for 30-45 seconds
6. After a few seconds let go of the knob and turn it to "on"
7. Check your thermostat make sure it is not on "vacation" and turn it up to see if the burner ignites.
You are ready for hot water if all works. Hope this helps you, have a good day.

The water heater pilot does not stay on?


The pilot light on hot water heaters is controlled by a thermocouple, a small copper rod that usually sits in or very close to the pilot light flame. When they go bad, which is not unusual, they do not allow the gas line to stay open and feed the pilot light. The easiest thing for you to do would be to replace the thermocouple. When following the pilot light lighting instructions, be sure to hold the valve button down for 30-45 seconds in order for the pilot light to heat the thermocouple prior to turning on the gas burner.
