  • To adjust the pilot light flame on a gas fireplace, many models will have  a “Low-High” button that permits you to adjust the flame up or down
  • On other models, you’ll find a screw that you can manipulate clockwise with a screwdriver to lower the flame
  • If you are having trouble, you might need to call in a specialist to check out what might be the problem
  • Check out this video to learn how to adjust pilot flames:


You can still stay warm and cozy with a gas fireplace even with the electricity out. Most ignition systems in our homes require electricity, but when you own a traditional gas fireplace, you need not worry because their ignition is based on a pilot light stand.

The pilot light flame is strong enough to power fireplaces, water heaters and furnaces. It relies on a thermocouple that sends electrical signals as long as the flame remains on. However, the pilot light may sometime need to be adjusted to work efficiently, which is easy.

How Should Pilot Lights Work?

Blue is ideally how your pilot lights should burn. You also should ensure that it doesn’t burn too dim or too bright leading to soot build-up. The flame may also turn yellow or orange. These are a few scenarios where you should adjust your pilot lights.

There are a few ways depending on what gas fireplace system you own. It may be remote-controlled, have control buttons at the bottom of the direct-vent fireplace, or have a screw that is easily adjustable with a screwdriver.

How to Adjust Gas Fireplace Pilot Lights

When pilot lights stay on, they keep the fireplace burning to keep us warm. It is vital to keep the flames stable and blue at all times. The user manual is also a great guide to adjusting pilot lights.

If the flame is of a different color (yellow/orange), these are a few ways how to adjust the pilot light flame on a gas fireplace:

Using a remote control

Use the remote control to adjust your pilot lights in these few steps:

  • Turn on the pilot lights. The flames should burn blue and not orange.
  • The remote control has an up and down button. Press and hold on to it until the fire goes out.
  • Now adjust the flames to your liking by using the same controls. You can choose to lower or raise the flames.

Using the controls located at the bottom of the fireplace

Just as we mentioned, it could have a high-low button. Like on the remote control, once you turn on the pilot light, use the button to adjust the flame to your liking.

When its control is a screw, all you will need is patience and a screwdriver, and if you have done it before, it will be easier for you. Here is how:

  • Take your screwdriver and turn the screw clockwise. This will reduce flame height. Counterclockwise increases the flame height.
  • You will know if the pilot light is burning okay when the flames turn blue.
  • If it is yellow, red or orange, keep adjusting the screw until it turns blue.

Can Cleaning your Gas Fireplace Pilot Light Help in Flame Adjustment?

Cleaning your gas fireplace pilot lights will get the pilot light burning better. A dirty pilot light causes misfiring, varying flame height, changes the color of the flame, and can even put the pilot light out.

You can clean it in two ways; inspecting it by disassembling it entirely or manually cleaning the unit’s combustion chamber. Both methods will help with the flame if done correctly. Always be careful when disassembling as parts may fall and break or get lost.

How to Perfectly Adjust your Gas Fireplace Flame

A gas fireplace is convenient and easy to maintain. However, the flame needs to be appropriately adjusted for you to enjoy its conveniences. See the following steps on how you can adjust your flame perfectly:

  • First, locate the gas control knob. It is located below the ceramic logs and is responsible for how much gas your fireplace uses. The knob has a small pointer and is usually black with ‘pilot’ written on it.
  • Rotate the control node to the pilot setting to light up the gas fireplace. Rotate it to the left and push it in, allowing gas to flow to the pilot light. Press the sparker or use a match to ignite the pilot light.
  • Release the knob and let the flame burn for about 60 seconds. Ensure the control knob is at the lowest flame setting.
  • Locate the switch, which should be marked ‘on.’ It should be found at the front of the gas logs. Move the switch to the on setting and ignite the burner as you observe the flame height.
  • After watching the flame, make the proper adjustment to perfect the flame height. Turning the knob to the right reduces the flame height, and turning the knob to the left will increase it. For ideal temperature, make sure the flame is at a height that will give you the heat you need.

How to Deal with a Pilot Light Outage

Gas fireplaces are a better option, but they sometimes experience issues like pilot light outages. Every time you light it up, always observe if the flames are blue and at the proper height.

When the pilot light goes out, rotate the pilot light knob to the pilot position. Push it in and use a torch lighter or a match to ignite the pilot light. Hold in the knob until it lights up. When it does, turn the knob to ‘on.’

Sometimes the outage may persist. If it gets to this point, seek specialist advice, and they can look deeper to see what the issue may be. It could be you have a faulty thermocouple making the problem persists.


Gas fireplace heating is one of the simplest ways to enjoy hours of warmth with little effort. They come with a user-friendly manual that is very useful for starting your fireplace.

With a bit of knowledge on the basic adjustment of your gas light fireplace and how to adjust its pilot light, you can be sure to keep a functional fireplace for a long time, especially all through winter.
