How to Turn on Gas Fireplace with Wall Key?

Gas fireplaces are a popular choice for individuals who desire a fire’s cozy ambiance, heat, and aesthetic appeal without the added work of a traditional wood-burning fireplace. Various gas fireplaces exist, some operated through a metallic key and others by a control panel or wall switches.

In this article, we will address the primary queries of how to turn on and off a gas fireplace operated through a key. Stay tuned to discover the step-by-step process!

How to turn on gas fireplace with wall key?

Turning on a gas fireplace operated with a key requires several steps. Here’s a step-by-step guide to help you get your fireplace up and running:

Step 1: Find the Keyhole

Finding the keyhole is the first step in turning on a key-operated gas fireplace. The keyhole is typically located on the left or right wall cavity but can also be on the floor. Look for a hole surrounded by raised metal or check the user manual to locate it.

Step 2: Insert the Key

Once you’ve located the keyhole, insert the key into the hole. Make sure to insert the key fully into the hole. Wall fireplace keys are usually between 3 and 6 inches long, with a flattened handle that makes gripping easier.

Step 3: Turn the Key Counterclockwise

Gently turn the key counterclockwise to see if there’s any give. Double-check that you have the right key if it’s not turning easily. Once the key starts to turn, continue to turn it counterclockwise until it stops.

Step 4: Ignite the Pilot Light

Once the gas is flowing, you need to ignite the pilot light. Use a long-barrel butane lighter to light the gas. Before you begin, check the lighter to ensure it produces a small flame. Once you’re ready, put the end of the lighter near the gas and press down on the trigger to light it.

Step 5: Adjust the Level

After the pilot light is lit, adjust the level of the flame by turning the gas valve key. Turning the key counterclockwise increases the flame’s intensity, while turning it clockwise reduces its intensity. Keep adjusting the key until you reach the desired level of fire.

What to do when your gas fireplace doesn’t have a key:

If you cannot find the key to turn on your gas fireplace, don’t fret! There are still ways to start the system, but it requires some DIY work on the components.

First, check if your system has an ignition knob or switch, as you may not need the key. However, if it does require a key, you can refer to the system manual for instructions on how to start it without one. Remember to turn off the gas supply before attempting any manual ignition, as it can be hazardous. If you’re not confident in starting the system manually, it’s best to seek professional help.

Ultimately, while it is possible to start a gas fireplace without a key, it’s essential to follow proper procedures to ensure your safety and the safe functioning of the system.

How to turn on a gas fireplace with a wall switch?

Modern gas fireplaces often have a wall switch, making turning the system on or off easy. The switch can also be used to adjust the flame’s intensity.

To start the fireplace using the wall switch, simply flip the switch to the ON position, and the pilot should ignite automatically. If the pilot doesn’t turn on, you may need to manually ignite it using a long-barreled lighter.

However, if the pilot still doesn’t light, it may be an indication of a more a significant problem with the system that requires further investigation before attempting to use it again.

It’s worth noting that some wall fireplaces with a wall switch also feature a keyhole as a backup in case the switch becomes inoperable. This keyhole can be used to turn on the system if needed.

How to turn on a gas fireplace with a control panel?

If your gas fireplace has a control panel, locate the red pilot-igniter knob. This knob should have two options, OFF and PILOT (or ON).

  • To start your gas fireplace with the control panel, follow these steps:
  • Turn the knob from OFF to PILOT (or ON).
  • Press the knob, which will release gas into the system.
  • Continuously press the igniter button once per second until the pilot light ignites.
  • Once the pilot light is lit, hold the button down to ensure the flame stays on.
  • Release the pilot-igniter knob. If the flame doesn’t go out, switch the knob to the ON position.

Things to keep in mind while turning on the gas fireplace with the wall key:

When turning on a gas fireplace with a wall key, there are several important things to keep in mind to ensure safe and effective operation:

  • Locate the key and ensure it fits correctly before turning on the fireplace.
  • If the key is missing or doesn’t fit, don’t attempt to force it or use an alternative tool. Instead, contact a qualified technician for assistance.
  • If you’re unfamiliar with the system, consult the manufacturer’s instructions or seek the assistance of a qualified technician before attempting to turn on the fireplace.
  • Make sure to shut off access to the gas supply before attempting to manually light the pilot light or tinker with the system in any way.
  • Always exercise caution and follow proper procedures when manually lighting the pilot light or attempting to start the fireplace without a key.


Q1: Why won’t my gas fireplace turn on with a wall switch?

A: Clean or replace the igniter if your gas fireplace pilot light is on, but the system isn’t igniting when you push the button or flip the switch.

Q2: Can you manually start a gas fireplace?

A: Gas fireplaces equipped with electronic ignition wall switches are straightforward. Simply turn on the switch, and the pilot should ignite automatically. If the pilot doesn’t ignite, it may be necessary to light it manually.
