The Tools Needed to Light Pilot Light in Water Heater

How to light a water heater

Before lighting water heater pilot, you first need to secure the tools to do the job. Luckily, these are tools that you can acquire anywhere, and more importantly, they are most often found in your very own toolbox!

The tools to light a gas water heater pilot light are as follows:

  • A lighter – In many cases, you will need a lighter to ignite the pilot light.
  • A handheld flashlight (optional) – This tool can help you find the burner, especially if the water heater’s in a place with dim lighting.

Steps to Lighting Water Heater Pilot

How to light a water heater

Step 1: Find the access panel

The first step in lighting water heater pilot is finding your access panel; this is usually located under the gas valve. In some cases, you can just simply peer in the gap inside the heater, which is where we would light the pilot light on hot water heater.

Step 2: Locate the gas burner

To light a gas water heater pilot light, you have to first search for the gas burner. It would be stored inside the heater, and you would see two gas tubes leading into it.

Step 3: Twist the gas knob

Find the gas knob with a label either saying “Pilot” or “Pilot Light.” Twist the knob so it would be pointing towards “Pilot,” then press down on it. This would allow gas to flow in and help you light the flame.

Step 4: Light it up!

While you hold down the gas knob or button, light the pilot light.

For many water heaters, using a long lighter to relight pilot light water heater is recommended. In other models, there are ignition buttons, usually colored red or black, that when pressed, would create a spark to light pilot light on water heater.

When the flame is lit, continue to press down on the gas button for a minute or so to make sure that the pilot light on hot water heater would stay lit.

Step 5: Turn the gas knob to “On”

Once you’re convinced that there is a strong flame going on, slowly turn the gas knob to “On” to activate the main burner. You might hear a distinct whooshing or even a “whump” sound when the main burner ignites.

Step 6: Close the access panel

Now that you have turned on the pilot light of your water heater, close up the access panel, making sure that you securely close it.

After you relight the pilot light, it might take a while for the water to be fully heated, but in about 40 minutes to an hour, your hot water should be flowing as if nothing ever happened.

If you’re water won’t heat up, the pilot light on your water heater may have blown out. Lighting a water heater is simple, no matter what type you have.

Most newer models of gas water heaters have a simple ignition switch. In just a few steps the water heater is lit, no problem. If you’ve moved into an older house, though, you many have the kind of water heater that needs to be lit manually. Here’s how to light both types of water heaters.

Do you have a manual water heater?

There’s a simple way to tell if you have an automatic or manual gas water heater. Look at the box sticking out of the side of the water heater that has two different dials. If it is an automatic, it will have a small ignition button next to the big On/Off/Pilot dial. If it’s a manual, there won’t be a button.

How to light a water heater

The On/Off/Pilot dial is typically on the top of the box while the temperature dial is on the side. This automatic water heater has a green ignition button by the On/Off/Pilot dial.

How to light an automatic water heater

The first step is turning off the gas by first looking for the knob labeled On/Off/Pilot. You’ll want to turn the knob past Pilot to the Off position. Let any built-up gas that may be in the system dissipate for five minutes.

Now, it’s time to start the lighting process. Turn the water heat dial to Low and the On/Off/Pilot dial to Pilot. Then, turn the On/Off/Pilot dial downwards and push the igniter button at the same time. Let go of the igniter button, but keep pressing the Pilot dial downward for around 30 seconds. You should hear a “whoosh” sound when the gas is lit.

If you take off the little door below the ignition box, there will be a little window you can peek into to see if the there is a flame. If it’s lit, finish up by putting the door back, turning the dial from Pilot to On, and turning the water temperature dial from Low to the setting you like. If it isn’t lit, you’ll need to start over right away to prevent gas build-up.

How to light a manual water heater

To light this type or water heater, I suggest grabbing a long barbecue lighter. The pilot will be a little tricky to reach otherwise.

First, take off the plate that is below the box with dials on the side of the water heater. There may also be an inner plate that you will need to slide to the side. Then, you should see a pipe(s) leading to a burner.

Next, turn the knob on the box labeled On/Off/Pilot past Pilot to the Off position. Then wait for five minutes to let any remaining gas dissipate. Turn the water temperature dial to Low and the On/Off/Pilot dial to Pilot. Push the On/Off/Pilot dial downward with one hand while lighting the barbecue lighter with the other.

Quickly hold the barbecue lighter over the end of the pipe by the burner. The flame should light instantly. Keep pressing the Pilot dial downward for around 30 seconds and turn the dial from Pilot to On. Then, finish by putting the plates back over the burner hole and set the water temperature dial to your desired temperature.

Important: If the burner doesn’t light within a few seconds, start the process over again. If you keep trying for a longer period of time, gas can build up and cause an explosion.

No Hot Water – Gas Water Heater – Remove the inner and outer burner access covers and check to see if the pilot light is lit. * Caution: Most modern water heaters no longer use standing pilots. They use electronic ignition to ignite the gas. Do not attempt to manually light an electronic ignition system.

Also, is it dangerous if the pilot light goes out on water heater? A device called a thermocouple is heated by the pilot light flame. As long as the thermocouple remains hot, gas is supplied to the pilot light. If the pilot light goes out, the gas is shut off and there is no danger of gas accumulating because the pilot light is out.

Thereof, how do I know if the pilot light is out on my water heater?

The pilot gas line is a small metal tube below the burner assembly and distinctive by the slight upturn at the end. It will be apparent, if the pilot is lit, by the small blue flame burning at the end. If you do not see a small blue flame burning, the pilot light is out.

Why is my water heater not working?

A water heater that produces no hot water may not be getting power, or it may have a tripped limit switch or one or more failed heating elements. First, check the water heater’s circuit breaker in the service panel to make sure it hasn’t tripped. If the breaker has tripped, switch it off, then switch it back on again.

Your thermocouple is responsible for sensing when your pilot light is lit.“any residential gas or electric water heater that has been flooded must be replaced.

Using the gas control light the water heater as follows:

  1. Read the safety information
  2. Turn the gas control knob fully clockwise to the “l” (off) position.
  3. Wait five (5) minutes so any build up of unburnt gas can escape. If you then smell gas, stop and follow “C” in the safety information. If you do not smell gas, proceed to step 4.
  4. Turn the knob to the “Õ” (pilot) position.
  5. Depress the knob fully (until star disappears below housing) and after 30 seconds, whilst keeping the knob depressed, repeatedly press the igniter button (for up to 40 seconds) until the pilot flame ignites.

6. Keep the knob depressed for 20 seconds after the pilot flame lights. The pilot can be checked by looking through the large opening below the gas control.

7. Release the knob and check the pilot is still alight.

8. If the pilot has failed to light or has not remained alight, turn the gas control knob to the “l” (off) position. Wait five (5) minutes for any unburnt gas to escape and then begin again at step 3.

9. When the pilot flame remains alight with the gas control knob released, turn the knob anticlockwise to the setting of „6‟ for a Rheemglas or Optima model, or to the setting of „7‟ for a RheemPlus model. These settings will give a water temperature of about 60°C („6‟) and 65°C („7‟) respectively.

10. Refer to “Temperature Adjustment” on page 5, if further temperature adjustment is required.

11. Replace the access cover.

The main burner will now automatically ignite when heating is required and extinguish when the water has been heated to the set temperature. If the main burner does not light at the selected setting, the water may already be at the selected temperature.

Your hot water heater pilot light holds tremendous power over you. If you’ve ever stepped into your shower on a cold winter morning — with body shivering and teeth chattering — as you wait for hot water that never comes, then you know I speak the truth!

If you own a gas water heater, this can mean one of two things. Either (1) the gas supply has been shut off or (2) your pilot light is out. Let’s first (and quickly) deal with the possibility that your gas supply has been shut off.

1. How to Make Sure Your Gas Supply is On

  1. Find the shut-off valve to your gas line.
  2. The shut-off valve usually is found close to your gas meter (see illustration below), which is located on the side or front of your home or main building.
  3. Make sure the shut-off valve connected to your gas line is in the “ON” position.
  4. If it is not in the ON position, then the problem is not with your gas line.
  5. If it is in the OFF position, turn the valve to the ON position. Feel free to call your local gas company for advice.

How to light a water heater

The first step in diagnosing the lack of hot water is to check your gas line. Make sure the gas shut-off valve is in the ON position.

If all is okay with your gas supply, then it’s time to check out your water heater pilot light.

2. How to Light Your Pilot Light Water Heater

The process of relighting a pilot light is different for each manufacturer. Fortunately, there are only a few manufacturers. Your first step should be to look for the instructions usually glued onto your water heater. Don’t worry if you can’t find them. We have specific brand-by-brand instructions written below.

This guide explains in detail how to light a water heater with electronic pilot when starting a new unit or restarting one after repairs or service.

If you’re unsure what type water heater you have, the Tools & Specs to Keep in Mind section will assist you in determining if your water heater has an electronic pilot. There are tips for keeping you safe when working with gas too.

How to light a water heater

Why You Might Need to Light a Water Heater

The pilot needs to be lit when:

  • A newly installed unit is first started;
  • The gas has been shut off for repair or service;
  • The water heater stops heating for no apparent reason.

If the last scenario occurs, check that the gas valve handle is parallel to the gas line to indicate it is in the on position. Then, look for a small blue pilot flame in the small window at the bottom of the heater.

If there is no flame and the gas is on, the steps below describe how to light a water heater with electronic pilot. If the pilot is on and the dial is set to hot or one of the hotter settings but the unit still isn’t firing to make hot water, your problem is more likely the gas valve, thermocouple or thermostat and should be diagnosed by a professional.

Tools & Specs to Keep in Mind

Water heaters are fired in one of three ways. So, knowing the type you have is essential to lighting it:

  1. Standing pilot, electronically lit: Many newer water heaters require that you know how to light a water heater with electronic pilot. They have a gas control that looks like this one made by Honeywell. Look for a status light that blinks when the pilot is lit and a small igniter button, possibly with a lightning bolt symbol next to it.
  2. Standing pilot, manually lit: If your water heater is quite old, it might not have an electronic pilot. There will be no status light or ignition button. We recommend you contact an HVAC company that repairs old water heaters for information on manually lighting the pilot or to discuss replacing the water heater.
  3. Electronic ignition without a pilot: Some newer units don’t have standing pilot light, that is, one that is always lit. They fire only when water heating is ncessary. Clues that you have one of these models are that it is newer and does not have an ignition button. If the unit isn’t lighting, it is probably a faulty thermocouple or gas control valve.

How to Light a Water Heater with Electronic Pilot in 6 Steps

If you’re sure your water heater has an electronic pilot (type 1 above), locate its gas control assembly. It is a box attached near the bottom of the unit with a rotating control knob or dial, igniter button, status window, wiring and the gas line attached.

Here are step-by-step instructions for how to light a water heater with electronic pilot:

  1. If the water heater has electrical wiring for a fan or other function, then make sure its circuit is on;
  2. Turn the gas valve to the on position, if necessary;
  3. Rotate the gas-control knob or dial to the pilot position;
  4. Depress the knob. Then, hold it down while completing the next step;
  5. Press the ignition button about once per second. Take this action until you see the status light begin to blink every few seconds. This indicates that the pilot is lit. The process that takes up to 60 seconds in a newly installed unit;
  6. Once the pilot is lit (its blue flame can be seen through the small observation window), turn the knob to the hot position or a hotter setting, if you prefer. Then, listen or look for the gas burner to fire.

If the burner stays lit, you know how to light a water heater with electronic pilot!

Bonus Tips

If the water heater doesn’t fire, there are two more tips that might solve the problem.

  • Sometimes, the pilot will go out before you can turn the knob to one of the water temperature settings. This is because the thermocouple hasn’t heated sufficiently. If that happens, wait 10 seconds before adjusting the knob from pilot to a temperature setting.
  • If repeated attempts to light the pilot and water heater fail, look for a small reset button at the base of the unit with wiring to it. Also, if your water heater has one, press and hold it for five seconds. Then, retry the process.

Caution Notes

Never try to light an electronic pilot with mechanical means such as a match or barbecue lighter. If you can’t get an electronic pilot lighted using the steps below, the control assembly might have to be replaced before attempting to use the appliance.

Before starting any gas appliance, check the gas connection to make sure it tight. NEVER check for a gas leak with a flame. Mix a few drops of water with a few drops of liquid dish detergent, and apply the solution to the gas connection. View the connection from all angles. Bubbles in the solution indicate a gas leak. If bubbles develop, tighten the connection, and test it again. Also, check to ensure that the installer wrapped the pipe with gas-sealing PTFE tape, which is very thin and yellow. If you don’t see it, turn off the gas, disconnect the line and add the tape before reconnecting and testing the line.

If a gas leak persists, turn off the gas, air out the space and call an HVAC professional for assistance.
