6 Things To Know About Converting Your Wood Fireplace to Gas Logs

A crackling wood fire can be charming, but anyone who owns a traditional wood-burning fireplace knows it comes with extra work. Between hauling wood, dealing with messy ashes, and waiting for logs to burn out, a relaxing evening can quickly turn into a chore. That’s why many homeowners are choosing to convert their wood fireplaces to gas logs. Gas logs provide the same warm glow without the hassle of firewood, and with modern designs, they look remarkably realistic.

If you’re considering the switch, here are the main things to know before buying gas logs for your fireplace.

1 – Gas Logs Are Designed for Wood-Burning Fireplaces

Gas logs are intended to be installed inside existing wood-burning fireplaces, not in fireplaces that are already fueled by gas. If you currently have a wood-burning setup, you’ll find that gas log sets are designed to fit directly inside, giving you the look and feel of a natural fire with the convenience of gas. For those who already own a gas fireplace and aren’t happy with it, there are other upgrades available that can improve its look and performance.

2 – Your Fireplace Type Determines Your Gas Log Options

The kind of fireplace you own will decide whether you should buy vented or vent-free gas logs.

• Vented Gas Logs – Known for the most realistic flame, vented logs must be used in a functioning wood-burning fireplace with a chimney or flue. When using them, the damper stays open so the flame burns naturally, similar to real firewood.
• Vent-Free Gas Logs – These produce more heat since they don’t require a chimney. However, they can only be installed in fireplaces approved for vent-free systems, and some areas have restrictions on their use.

Understanding your fireplace setup before you purchase is key to choosing the right type.

3 – Proper Sizing and Space Are Essential

When buying gas logs, size matters. Gas log sets require space around them to allow airflow and prevent overheating. If you’re unsure which size fits best, it’s often smarter to go slightly smaller. Keep in mind that it’s not just the log length that matters—pilot lights, burners, and other components also need clearance.

4 – Check for a Gas Line and Burner System

Before you can switch from wood to gas, your fireplace needs to have a gas line installed. If you don’t already have one, a licensed professional will need to run a line to your fireplace. If your fireplace already has a log lighter connected to a gas line, upgrading to a full burner system is usually all that’s required.

5 – Local Codes May Require a Permit

Because working with gas involves safety regulations, you may need a permit to complete the conversion. Always check your local building codes before purchasing and installing gas logs. Certain regions also have rules on vent-free logs, so it’s best to confirm before you buy.

6 – Chimney Maintenance Is Still Important

Switching to gas logs doesn’t mean you can stop maintaining your chimney. Vented gas logs still produce some soot, and your chimney may be vulnerable to animals, moisture, or structural cracks. Even with gas logs, regular chimney inspections ensure your system continues to function properly and safely.
