  • Gas Fireplace Parts –  These guys are awesome.  They have an extensive library of Parts manuals and all the parts you would need to fix your fireplace.  Not to mention a great support staff!

Valve Troubleshooting PDF Guides:


      • Gas Fireplace Glass Cleaner – it takes off those white deposits (this is actually a calcium deposit), it leaves a protective coating to prevent future buildup, and it does not contain ammonia (like windex) which can actually harm the inside coating on the glass.
      • Gardner Bender Digital Multimeter – An inexpensive but reliable device to test voltage.  This is probably the most useful tool in gas fireplace repair.
      • Glowing Embers – this simulates glowing embers and will actually add more glow to make it look more realistic.
      • All-in-One Screwdriver – My favorite screwdriver.
      • Compact Vacuum with Brush Attachment -a nice and compact all purpose vacuum to clean off the logs.  You can use your own household vacuum but I like to have a vacuum like this for those “extra dirty” jobs.
      • Gas Leak Detector – Think you smell gas?  Find out for sure with this electronic gas leak detector.  Will detect small traces of natural gas, propane, or methane

    I am trying to find out why a gas fire place would need a thermocouple as well as a thermopile since they both appear to do the same thing? Are you able to cover this on your web site please? Rod W, Ottawa

    • mygasfireplacerepair

      Hi Rod,

      Inside the control valve are two electro-magnets; one controls the gas to the pilot light, the other to the main burner. The one that keeps gas flowing to the pilot is not very large and only requires around 10-30millivolts of power to stay open. The thermocouple is perfect for this because it produces around 30 millivolts of electricity but more importantly it also cools down a lot faster than the thermopile. So that if the pilot light blows out, gas will be shut off to the pilot light almost immediately.

      The thermopile is basically like a large group of thermocouples. The main burner is a larger electro-magnet so it needs more power to open up so the thermopile (otherwise known as millivolt generator) provides enough power so that the electromagnet can open up.

      I hope this helps.

    If you can, you should replace it.
    Most of the time this is designed to make sure exhaust gasses do not vent back into your living space. They use heat to sense this. If you bypass it, you take the chance of the fireplace venting into your dwelling without knowing it.

  • mygasfireplacerepair

    Yes, this is a risk. Chances are, you will not have any problems. If you bypass the snap disc i would purchase a carbon monoxide detector.

    Hi. My gas fireplace won’t stay lit. I’ve had the installer out twice. Now he tells me that I don’t have enough pressure in my gas lines. Also, because the fireplace is at the end of my gas flow, the pressure isn’t sufficient to keep the pilot flame lit. I’ve never heard of this before and wonder if he’s blowing me off because he can’t figure out the problem. Have you ever heard of “insufficient gas pressure” as a cause for a fireplace/pilot to not stay lit? Thank you.

    • mygasfireplacerepair

      Gas pressure can be an issue. Each fireplace will have a normal acceptable range for gas pressure. The tech should be able to check this with a monometer (gas pressure testing device) to determine if it’s within this range. Many times you can have your local gas service provider increase your gas pressure at your meter. You could ask what kind of guarantee there is if increasing the gas pressure does not work.

    Hello, forgive me if I’m in the wrong part of the Forum but I have a question that I hope somebody can assist me with. I do quite a bit of handyman work in my neighborhood and I’ve been presented with this scenario. A gas fireplace was still functioning properly however they smelled gas. They called in professional technicians that told them they had a gas leak and they would have to get the replacement part. Charged them $90 and went on their way. After a number of weeks with no contact the client called the company, and was essentially informed that the part could not be located.. Sorry. Any company that would not follow up with any size gas leak is untrustworthy. At my request they called back to try to get what part needed replaced. This is the information he received …..

    Monnessen Hearth Systems. M/in IDV380NV. sn 05-C- 113793 He said it was the gas valve pilot assembly –

    Is this techs information a true possibility, and is this systems gas valve pilot assembly one offered through this sites links. I would like to prove techs diagnosis before acting on it.


    • mygasfireplacerepair

      Hi Robert. Is the gas leak at the pilot assembly or the gas valve? From what I can find, the gas valve and pilot assembly should still be available. Could you post pictures of both? Or feel free to e-mail them to

    I’ve had ALL my parts in the gas fireplace in my condo COMPLETELY replaced and confirmed there is no issue with gas supply. It still goes out after a ‘variable’ amount of time (15 minutes to a couple hours). Three techs have made the visits and now exhausted all issues with possible faulty parts or gas or blocked two-way venting (used a camera).. The third fellow said his company originally installed the unit and that it appears the condo design did not properly accommodate what was needed for the rise and run of the vent pipe (can’t remember which number didn’t add up)…and that the unit runs out of oxygen – timing might depend on wind patterns. Soooo…how the heck do I solve that?? I could crack the glass open, but is that safe? Is there a mechanical forced air feed unit I could somehow install. Unfortunately, I’m on the top fifth floor and can’t even reach the end of the exterior pipe from a window. I’m at a loss…

    • mygasfireplacerepair

      If the fireplace was installed beyond the venting limits, then it should have never been installed. Whoever installed the fireplace originally should be responsible for proper installation. At this point your only option may be to install a power vent. Many fireplace brands will allow a power vented cap to be installed in these situations, but I would try to get the original company that installed it to fix the issue.
