How do you light the pilot light of a Pentair MiniMax 100MV gas pool heater?

Pentair Mini Max does not have a pilot light, it has a Electronic ignition. If your having trouble getting it to fire up you could have a problem with a plugged burner, bad ignition or a bad valve.


When the pilot light is off does the water heater still fill up?

The water continues to run into and out of the water heater. There is just no flame to heat it up.


Why doesn't my hot water heater light everytime?

If it is gas operated, the hot water heater may not light because it may have a defective millivolt sensor. The millivolt sensor is heated up by the pilot and generates a fractional amount of voltage telling the gas valve that the pilot is lit and the gas valve can now be safely opened to heat the water heater.


What does a pilot light do on a heater?

it heats up the thermo couple which opens up the gas control valve allowing gas to flow to the main burner. if the pilot goes out the thrmo couple will cool and shut the gas valve so gas does not come out


How do you light the pilot on a atlanta superflame?

In the middle of the unit is the pilot , while setting valve to pilot (note if u push down on the pilot valve u will here gas-do not hold for long or to much gas will accumulate) light within 1st five-10 secinds. If u dont light right away turn off and wait 5 minutes. Then try again, when pilot is depressed hold lighter above where gas line goes to center of heater. You should have heat-the green knob that says lo-hi is the adjustment. Turn to hi and the furnace should fire up...


98 expedition do the overhead heater controls light up?

Yes, the overhead heater controls do light up.


Hot water heater hasn't been hooked up to gas for 4 months will the burner light right away?

No reason why it shouldn't. You will find a black dial for the temperature settings, to light the pilot light, there will be pilot light start setting, press the black dial in and hold it, light the pilot light and hold the dial down for about 10 seconds. The light should stay lit, once it does turn the black dial to the desired teperature setting.


Why won't your laars lite pool heater turn on The heat exchanger temperature sensing bulb and siphon loop assembly have all been replaced with no leaks.?

When was the last time the filter was cleaned? Have all the components in the heater system been checked for proper values? Does the heater sound as if it wants to fire up? Does it have a pilot light or electronic ignition? Have the orifices been checked for bugs or spiders? Ken


How do you light the pilot on your Maytag Performa Dryer?

Maytag Performa Gas Dryers don't have pilot lights. This form of ignition went out of favor decades ago. They now use an igniter glow coil( the heater element) that heats up to a glowing red color to light the main burner.


Water pool heater trouble shooting?

A number of problems can cause a swimming pool heater not to work. The most common I have found is lack of water flow. A heater needs a certain amount of water flowing through it to work correctly. The next most common problem is due to the pilot not lighting or remaining lit. This is usually due to the pilot generator not working. When you light a pilot light and have to hold it for a length of time before releasing the button you are allowing the pilot generator to heat up and then stay open to keep the pilot lit. Usually you need a licensed person to do work with changing items on a gas unit. The thermostat can be a problem for any water heater. Most of the heaters I have worked on were gas. If you have an electric heater waterflow still needs to be checked and the electrical connections can become corroded in the presence of chemically treated pool water.


Pool heater pilot will not stay lit?

Make sure the gas valve that is part of the supply line is on. There is another gas valve inside the heater, which has three positions: OFF, ON, and PILOT. Turn the valve to PILOT, then press it down. This will allow gas to flow to the pilot light, so that at this point it should be able to be lit with a match or better yet, one of those butane fire starters. Continue to hold the valve down, for about 30 seconds. When you release it, the valve should come up, so that you will be able to turn it to the ON position. If the pilot is still burning, you should be good to go. If the pilot goes out, however, there is a chance that the pilot generator, a $50 or so brass cylinder that is positioned near the pilot light and which produces about 500 mv, is bad. The pilot generator puts out enough power, using the heat of the pilot light, to energize a coil inside the gas valve to keep the gas flowing to the pilot. If there is no power generated by the pilot light, the gas valve will shut down (it's a safety feature so that the gas to the non-burning pilot does not continue to flow and create an explosion hazard). You will need a digital voltmeter to check the pilot generator, and some other wrenches to replace it if it proves to be not producing at least 400 mv when hot. Assuming the pilot stays lit, your next job will be to ensure the other limit switches in the circuit are OK, and that the thermostat is working OK to actuate the second coil inside the valve the turns on the gas to the burners. Your question, however, was only about the pilot light, so I will leave it at that. I also have a Teledyne Laars natural gas pool heater and I found this answer when trying to figure out how to light mine. The previous answer was correct although it didn't tell you where the pilot light was (where you put the flame in order to light it). On mine, you should follow a thin pipe from where the blue circular pilot/on/off switch is. It goes from left to right and then goes back. On the right hand side, there should be a sign that says "pilot light here" with an arrow pointing back. The actual tube it points to is the pilot light. You should use a long match or a butane fire starter to place a flame along the top of this tube. Turn the blue switch until it can be pressed down. When you press it down you should hear gas flowing (a light hissing). If you don't, there is no gas getting to the appliance. Follow the pipe from the meter to the appliance and check for the gas turned off along the way (I have two shut-offs - one at the meter and one at the heater). While pressing the blue switch down, hold a flame to the tube on the right. It should light the gas. Continue to hold the blue switch down for 30 seconds or so. I think it is heating something at the back. If you release the blue switch and the flame goes out, repeat the process. Eventually, you'll see an orange flame at the back as things start to heat up. When you release the switch, it should stay lit. Please note these instructions are from my perspective - your situation may differ. Use these instructions at your own risk. If in doubt, have your pool heater serviced by a furnace cleaner. Jim
