How to Start a Gas Fireplace: A Simple Guide for Every Ignition Type

Learning how to start a gas fireplace takes just a few minutes once you know which ignition type you have. Most modern units turn on with a remote or wall switch, while older models need you to light the pilot by hand. At Embers Living, our team helps homeowners do this every day, so this guide walks you through each method step by step.

Identify Your Ignition Type

Before you do anything, figure out how your fireplace ignites. This single step is the key to learning how to light a gas fireplace the right way, since each system lights a little differently.

Not sure which you have? Look for a control panel behind the lower louvers, or consult your owner's manual.

How to Light a Gas Fireplace With a Remote or Electronic Ignition

This is the easiest way to light a gas fireplace. Learning how to light a gas fireplace with electronic ignition simply means pressing the “on” button on your remote. The pilot ignites within a few seconds, and the main burner follows shortly after.

If nothing happens, replace the batteries in both the remote and the receiver inside the firebox, then try again. Many people who ask how to light a gas fireplace with electronic ignition find that dead batteries are the only problem.

How to Use a Wall Switch to Turn on a Gas Fireplace

If your unit is wired to a wall switch, turning it on is as easy as flipping the switch to the “on” position. Give the system a moment to ignite the pilot and burner. Go to the troubleshooting section below if you hear clicking but do not see a flame.

How to Turn on a Gas Fireplace Using a Wall Key

Some fireplaces use a wall key that controls a gas valve near the hearth. Here is how to turn on gas fireplace models with a key valve:

1. Insert the key into the valve in the wall or floor.
2. Hold a long lighter near the burner ports.
3. To release gas, slowly turn the key counterclockwise.
4. The burner should light right away. Remove the lighter once flames appear.
   
   

Always have the lighter at the burner before you open the valve, and never let gas flow without a flame ready to light it.

How to Light a Gas Fireplace Pilot by Hand

For a standing pilot system, you will light the pilot manually. This is the most hands-on way to learn how to light a gas fireplace, so take your time:

1. Locate the control knob and turn it to “off.” Wait at least five minutes to clear any gas. 
2. Turn the knob to “pilot.”
3. To give the pilot gas, press and hold the knob down.
4. Until the pilot illuminates, keep pressing the igniter button.
5. Hold for 30 seconds, then let go.
6. Set the main burner to “on” by turning the knob.

Suppose you smell gas at any time, STOP. Air out the room and call a professional.

How to Light a Propane Fireplace or Gas Logs

The steps above also explain how to light a gas fireplace that runs on propane. Just confirm the tank valve is open and the regulator is working first. For match-lit gas logs, hold a long lighter to the burner while slowly opening the gas valve.

Troubleshooting a Fireplace That Won't Start

If you have followed the steps to light a gas fireplace and it still won’t ignite, run through these quick checks first. Often, you can fix the issue and learn how to turn on gas fireplace units yourself without a service call:

• Clicks but no flame: the gas supply may be off, or the pilot tube is dirty.
• Pilot won’t stay on:  you may need to clean or replace the thermocouple.
• No response at all: check batteries, the breaker, and the wall switch.
• Keeps going out: a faulty thermocouple or draft is often the cause.

Final Thoughts

Starting a gas fireplace is simple once you understand your ignition type. Whether you have a standing pilot, electronic ignition, or intermittent pilot system, following the correct steps ensures safety and reliable performance every time. With regular maintenance and proper usage, your fireplace will provide years of warmth and comfort.
