Repairing Your Fireplace Yourself Is Easier Than You Think

Repair Your Gas Fireplace Yourself?
After 5 years of experience repairing, installing, and servicing fireplaces, I found most of the service calls I would go on were minor repairs or adjustments that would often take 15 minutes or less.
I would then be stuck handing the customer a $125 service charge, for something that could easily be fixed or adjusted themselves.

Thankfully, there is another way.  With a little bit of knowledge, you’ll find that your fireplace is really not all that complicated.  And that if it malfunctions, there are at least a few things you can try before getting a professional involved.

The main goal of this website is to give you clear, concise, instruction and knowledge so that you may not only learn more about the function, maintenance, and operation of your fireplace, but also be your first “go to” source for troubleshooting problems.  (In essence, saving you money).

Fact: most people are afraid of their fireplaces. This fear is perpetuated by a lack of knowledge and understanding as to how their fireplace works, and how to safely service a gas fireplace.

If you want to start at the beginning, please visit the Fireplaces 101 page, where you can learn about how gas fireplaces operate.  Otherwise please visit the posts to the right to begin troubleshooting and repairing your fireplace.

If you are still stuck, you can always visit the Find Certified Technicians page where you can locate a skilled NFI (National Fireplace Institute) certified repairman.

  1. I have a Vermont PDV20 gas fireplace.
    Pilot light will stay on, after 2 mins. holding knob in.(preheat).
    Then turn knob from “pilot” to “on” & it goes out.
    It has a Honeywell Valve/w Ignitor VS8420E (now discontinued)
    Is there a replacement valve ?
    What is the problem ?

    • Unfortunately it is the valve. Try this: VERY slowly turn the knob from “pilot” to “on”. Most of the time it will stay lit if you do this. This is a known defect with that particular valve and the only real solution is replacing it. If you look online you may be able to find a dealer that still has one. Otherwise take it to your local fireplace or HVAC shop and they should have a replacement that will work for you.

  2. I have a heat n glo fireplace that will not turn on I have power, new modular, what can be theproblem?

    • This sounds like an IPI or Electronic ignition fireplace. What is the model number?

  3. I have a Allen& Roth vent-free gas fireplace. Prob. is it does not alway’s turn on or off when it should. The remote shows the flame that means it should be on , but it is not.Have changed batteries at least 2 times per month. can u please help. Thanks

    • Some remote brands are very sensitive to outside interference. You may have to “re-learn” the remote to the receiver to reset it to a new frequency that will not have as much outside interference. Some brands require you to re-learn the remote 10 times in a row before it will switch to a different RF frequency. You may have to refer to the manual for your remote on the specifics.

  4. I have a DelRay 34DVI. Nothing happens when I flip the switch. Where do I start?

    • First make sure you have a pilot light. Start in the “h section.

  5. i need some one to come to house to repair my gas fire place

  6. I can’t thank you enough for this website. My fireplace was not lighting and the last time I had a problem, I was quoted $125 for a technician just to make a call. I tested the switch as suggested and that was the problem. Ninety-nine cents later, it works and I feel worthy of my own home repair show! Look out Bob Vila.

  7. We purchased a house a few months ago with a Heat-n-glo natural gas fireplace model number sl-750tr-ipi-d it turns on by a light switch. The pilot lights when we turn on the switch, but the main burner won’t light. Any help would be greatly appreciated!! Thank you!

    • This is an electronic ignition (or IPI) fireplace.

      Start by removing the decorative front off the fireplace (usually done by lifting up on the front then pulling out). This will reveal your main control valve area underneath the fireplace. The main control valve is silver and has a high/low knob and two colored terminals (one orange, one green). If you look on the orange terminal you will see an orange wire connected to it. Now look at the green terminal. This should have a green wire connected to it, which I’m guessing is not connected. Find the green wire and slide it on the terminal and it should start right up.

  8. So…we have black on the glass of our gas FP. This started some time ago. We called out a tech because we were having another problem. He ended up cleaning everything as well. We used the FP maybe two more times that season all was fine. Next season a few uses and the black. I googled. For help and recleaned everything including the little holes and made sure the logs were like they should be. I think the tech put them back wrong. Anyway black again. What is up??

    • I sounds like you need to open your air shutter more. Your flame should be blue and yellow, (no orange or black tips).

      The air shutter is located around the main burner orifice and controls the mixture of air to gas. There is usually a screw you can loosen to rotate the shutter to open it up and allow more oxygen. More oxygen = less soot = leaner burn.

  9. Do you happen to have a guide to flame adjustments? I just installed my Kozy Heat Princeton. It has the new IPI system in it. Turns on fine, etc. I cant figure out what I need to do adjust the flame height. On back inside of the box is an adjustment for air intake which i set to “2″ based upon the vertical pipe we have for it. The last adjustment i assume would be the Venturi pipe. For the life of me, I dont understand how it works.. does it control the amount of NAT into the burner plate or flow? When the fireplace is on low, Im simply getting low blue flames. On high.. I only have (2)flames just above the logs, where I see a video on you tube showing it higher. No worries if you have no tips. figured I ask anyways.

    Thanks!

    • The venturi adjusts the air to fuel mixture for the flame. The more you close the venturi, the more yellow the flame will become (and larger it will appear). The venturi on this unit is adjusted but removing the hex head screw on the lever next to the control valve. You can pull this lever toward you to adjust the mixture. If you close the air shutter too much, the flame will appear orange with black tips and it will cause a lot of sooting. Its best to find a good balance between flame appearance and a clean burn.
