Buying guide
Explore vent-free gas logs for a fireplace flame display without a chimney connection. Choose a model approved for your fireplace, room and location.
Check the installation requirements
Vent-free systems use room air and have specific requirements for room size, ventilation and placement. Have a qualified installer review the exact model’s instructions, and confirm with your local building department that the installation is permitted.
Find your style and size
Compare the log textures and flame displays in product photos and videos. Measure your firebox’s front width, rear width, depth and height, then check them against the minimum dimensions for the selected burner and controls. Use only the approved logs, burner and accessories together.

Questions people ask before they order
How can ventless logs operate without a chimney?
A vent-free set burns gas without a chimney connection and uses room air for combustion. It must be installed in a suitable space with the ventilation required by its manual. Use only the approved logs, burner and controls together.
Are ventless logs legal everywhere?
No. Rules vary by state, city and installation. Ask your local building department and installer whether the specific model is permitted before ordering.
Do ventless logs produce moisture?
Yes, burning gas produces water vapor. Follow the selected model’s room-size and ventilation instructions, and ask your installer to assess whether it suits your home.
How are ventless logs different from wall heaters?
Vent-free logs provide a fireplace flame display; a wall heater is a separate appliance. Compare each product’s approved use, output and installation requirements when deciding how to heat your space.
Are ventless logs as warm as vented?
Vent-free sets can provide supplemental heat, but suitability and output depend on the model and room. Ask your installer to help assess your heating needs alongside the ventilation requirements.
How realistic are the flames?
Flame appearance varies with the burner and log design. Use the product’s photos and videos to compare the flame, ember display and log arrangement you prefer.
