Pilot light on Lennox Hearth Products Fireplace - df054b39-87c1-4a9f-a901-4c143e29d664.jpg

A thermocouple creates 30MV and holds the pilot valve open in proving a pilot flame exists, it will not actually power anything but the pilot valve that must be physically depressed for 30 seconds after lighting.
The other is a Pilot Generator, it makes 750mv or 3/4 of 1 volt, they will have 2 wires that come off it and wont be screwed in as a thermocouple is usually.
If you have a 750mv system I use a AA battery with wire taped at each end of the battery, I then attach the leads to the terminals that the pilot generators leads go to, this will operate the gas valve fine if the gas valves ok, if not it will need to be replaced, do not run the unit via AA battery for anything but emergency or testing.

SOURCE: Propane fireplace insert won't light

Gas apliances have safety features built into them so you don't blow yourself up. The pilot heats a thermocoupler which tells the gas valve there is a flame, open the main gas to the burner. If you can see the flame area of the pilot look for a round post about 3/16 inch in diamiter. This should be directly in the flame, if not bend the bracket so it is in one side of the pilot flame. The thermocouple is attached to a mounting bracket. This will be held in place by a 1/4 inch hex screw. remove the screw and the capilary tube leading to the gas control valve. Before you do anything, close the main gas supply to the fireplace and disconnect the power to the fan. You may need to semi dismantle the fireplace to get the thermocouple. The gas valve end is a brass 1/4 pipe thread plug. Turn the outer nut and remove without twisting the tube. Reverse this order to install a new one. Besure not to twist the capilary tube, tighten brass nut 1/4 turn past hand tight. Your better heating supply house will have these in stock. Restarting the pilot will take a few tries because the gas was off. Your gas suplier would charge about $75 to fix this. if you don't have the proper tools and it dosen't look pretty stright forward don't do it. You could get dead.

SOURCE: Gas fireplace pilot flame won't stay lit.

Hi , you can try and pull the panel on the bottom of fireplace out and check the adapter in fireplace. Sometimes they go bad. When you open in also check to see if there is an adapter plugged in and a option to use the battery operated function. If this goes bad the pilot will not stay lit.

SOURCE: ProCom blueflame heater pilot light difficult to light

Holding the button down enables gas to go to the pilot. When it lights you will see the flame touching two rod like devices. The small one is the igniter. The second one is a thermocouple. A thermocouple is a bimetalic device (2 disimilar metals) that when heated produce a small curren, this current in turns keeps the valve open for the gas to flow when you let go of the button. This is a safety feature. If the flame goes out on the pilot the thermocouiple cools and closed the valve shutting off the gas so you don't go boom! It sounds like the thermocouiple is bad or missaligned. If it is missaligned it will take longer to get hot enough to hold the valve open. Another thought would be the flame is not shooting out far enough (not enough gas pressure, clogged oriface on pilot(previous writer, leak but you get the idea. In my manual it had a picture of how the flame should look hitting the thermocouple. Good luck. My problem is I assumed that the regulator on my construction heater was the correct size. Maybe not. I have not had any luck getting the pilot to light at all. I hope I have not damaged the internal regulator.

SOURCE: pilot light will stay lit Lennox G8D2-82

You may need to replace the Thermocoupler. It screws into the gas regulator and the sensor end is set in the flame of the pilot light. You can get one at any appliance parts store. The Thermocoupler simply feels the heat of the pilot light and sends a very small amount of voltage to the gas switch that opens when your thermostat calls for heat. If the pilot light isnt lit, no voltage from the sensor and no gas can be released by the regulator.
Anyone can replace one. Just find the tip that sits in the the pilot flame when you try to ignite the pilot light. Follow it down to the regulator and unscrew it. There is no gas involved. It is Ultra Low Voltage. No danger.
Be sure to turn off the power to the unit before you begin removal. Take it to the parts store along with your furnace brand and model number. If you see any identifiers on the regulator, note them and take them with. When you replace it be sure to have the sensor end up in the flame of the pilot.

Gas fireplace won't light


Your fireplace does have a pilot. It is either millivolt, where you manually light the pilot and use a remote or wall switch to light the logs
or is IPI where it still has a pilot light but the reote or wall switch lights the pilot first then the logs. The second version has a non-standing pilot. In either case, it sounds like a pilot assembly issue. When you "throw the switch", do you hear clicking inside the fireplace? If so and it does not light, you may have a pilot assembly issue. If there is no sound at all, then you may have a bigger issue with the control module. The only sure way to know which is the culprit is to have a certified technician come oput and examine your fireplace.

I HAVE A HC3820 AND AM CURRENTLY LOOKING TO OBTAIN A BLOWER. THE PROBLEM IS THAT THE ONE NEEDED FOR THIS MODEL IS FAK-1500 AND I CANT FIND IT ANYWHERE! PLEASE HELP!


Honestly, go to www.grainger.com. Since Superior/Lennox Hearth/and FMi are all merging into one company you are going to have a very hard time finding replacement parts for older Superior units. Plus the new company, Astria Fireplaces, is going to be using FMI for their woodburning products so no more Superior products available.
If you bring the old blower to your local Grainger they can match it up. I hope this helps.

Pilot flame bends upward


You more than likely need a new pilot assembly. If it is a HPC (Hearth Product Controls) unit contact HPC directly and see if they can give you a name and number of a dealer locally to service the unit you are discussing or diagnose the problem over the phone. HPC is actually very helpful and knowledgeable. If you call them 9 times out of 10 they can give you the solution, part number, and a dealer where you can purchase the part from locally. Just make sure to have the model and serial number before you give them a call. Contact

sounds as though you need to get the thermocouple(copper wire that sits in the pilot flame) replaced, check first to make sure it is tight at the gas valve end, as they can loosen over time due to expansion and contraction.

Mike, I suspect that the problem you're having is not related to the new Thermoplie (Pilot Generator) you installed. Its with the Thermocouple. The clue was "Some of the time its hard to keep the pilot light lit". The Thermopile controls the opening and closing of the gas valve, when the wall switch is turned ON/OFF. The Thermocouple, is what keeps the gas valve open and pilot light lit all the time. If there's no flame heat on the Thermocouple, it closes the gas valve. Rather than replace it, you can try polishing it with some very fine sand paper, then wipe the tip with a cotton ball soaked in alcohol. If the Thermocouple is really pitted, don't attempt this. Just replace it. If you do replace it, when you make the connection to the gas control valve, finger tighten the nut, then tighten only 1/4 turn more with the appropriately sized wrench.

By the way, MARCO is no longer in business as MARCO Fireplace. It was purchased by Lennox Hearth, a division of Lennox Heating. And your model firsplace is no longer manufactured. If you continue to have problems with it contact Angie Parrish at Lennox via email angie.parish@lennoxhp.com.

Hope this helped you solve the problem. Please be kind enough to rate my response to you. Thanks and have a good day!

It has a panel hidden under the white fiber hearth bricks at the front bottom of the unit. you need to clean the lava rock off of them, pull both of them up, and then you will see the hidden linear cover that allows you to access the valve and light.

I need help relighting the pilot light on my Marco mfg gas fireplace-model # 794015c


First, turn the wall switch to the off position. Second, turn the key all the way tcountercockwise to the open position. At the front of the unit, below the hearth opening there is a black front access panel. Should have a little recessed part. pull it out and expose the gas valve. Turn the plunger/knob that says off, on, pilot to the pilot position. You'll knw your in the pilot position when it lines up with the indicator (usually a red or black mark on the gas valve body). If you are in the pilot position, you will be able to push in the pilot (it will feel springy). Push the plunger in and then push the red button (piezo ignition button) in until it makes a snapping sound. You may have to do this several times because the air has to bleed out from the pilot tubing. This should light the pilot BUT wait. DO NOT LET GO OF THE PLUNGER ONCE THE PILOT IS LIT. You need to keep the plunger depressed for about 30 seconds and then let it go. After 30 seconds let the plunger go and verify the pilot is lit. If not try the last step over. After the pilot is lit, you may turn the plunger/knob to the on position. Now go back to the wall switch and flip it on. If it doesn't come on tap it hard. Sometimes dust can actually prevent it from making good connection. I work on fireplaces for a living and coincidentally worked on this model today. Simple as pie.

Marco gas firplace


I have a Model 792864B. Before you attempt to light the pilot light - make sure that any wall control switch or remote control for the fireplace is in the off position. Locate the gas supply line. There should be a gas supply valve to turn on the gas supply. The valve is usually painted a different color than the supply line like blue, green or yellow. Open the valve by pivoting the handle to be parallel to the gas line, usually counter-clockwise. When it is closed it is at a 90 degree angle from the supply line. Locate the pilot light assembly - this is the pilot light. There should also be a red or black ignitor button and a black or green valve control knob with the words "on" "off" and "pilot" on it. It may be located inside a black box, mine is marked heatolator, that has a lift off top. Lift off the top of the box. Push in the valve control knob and turn it until the word "pilot" is in line with the arrow (my arrow is red) or indicator line. While pressing and holding in the valve control knob - it presses in about 1/4", press the red or black ignitor button repeatedly (once per second) until the pilot ignites. Once the pilot is lit, continue to hold the valve knob in for about 30 seconds and then slowly release. The pilot should remain lit. If it remains lit, press in and turn the valve control knob to the "on" position. The on/off wall or remote control switch should now light your fireplace. If the pilot doesn't ignite, turn off gas supply valve, wait about 5 minutes and try it again.
