Many people who have wood-burning fireplaces ask if they can use vent-free gas logs in their fireplaces. They love their wood-burning fireplaces, but are tired of the mess, buckets of ash, and expense involved in buying, hauling, and dealing with wood. The answer is – Yes, vent-free gas logs are a safe and convenient alternative to using wood in your fireplace if you follow some basic guidelines.

It is critical to make certain your enclosure is suitable for burning vent-free logs. We also recommend you always carefully read any manufacturer’s instructions on your firebox to make sure they are suitable for vent-free gas logs.

A wood-burning fireplace: To safely burn vent-free gas logs in a wood burning fireplace, you should have a masonry fireplace that has a proper chimney. You need to be sure your fireplace is factory built and has been assembled properly in compliance with all instructions. Also, check to see if your manufacturer’s instructions for your fireplace disallow you from using vent-free gas logs in your fireplace. If you have lost them, you can often find them online. If your fireplace is a custom job, ask the mason or a building expert.

A vent-free firebox enclosure: It is safe to burn approved vent-free gas logs in tested and certified vent-free firebox enclosures. Mr. Vent Free offers a large selection of vent-free firebox enclosures.

Wood-burning stoves: Wood burning stoves have not been approved or tested for use with vent-free gas logs. We do not recommend anyone use vent-free gas logs with a wood-burning stove.

If your fireplace meets the safety requirements, there are some important advantages to burning vent-free gas logs in your wood-burning fireplace. Due to advanced technology, these logs burn gas so cleanly they can be burned with the damper closed — they will produce almost no exhaust. They also produce greater heat than wood, so you will be able warm the room more efficiently.

Do I need to make change to my fireplace in order to burn vent-free gas logs? Most of the time, the answer is “no.” However, we recommend you close the flue damper unless you find the logs are generating an odor or give off too much heat. In that case, you may keep the damper slightly open. Closing the damper makes sure you are keeping the heat inside your home and the energy is not being wasted. This makes vent-free gas logs much more energy efficient.

If I use vent-free logs in my wood-burning fireplace, do I need to use a hood? It is important to review your fireplace installation manual to obtain specific rules for clearance. The purpose of a hood is to reduce wall temperatures above the fireplace opening, so be certain to check your manual for guidelines.

An important tip to remember is that before you begin burning vent-free gas logs in your fireplace, have the firebox and damper area cleaned by a professional. If you have used wood in your fireplace, this will help to prevent wall staining or unpleasant residual odors.
