Gas logs are available for vented and vent free applications. Vented gas logs by design have a realistic flame presentation. They have a higher BTU input (gas volume) than vent free logs, which provides a stronger flame. Because the combustion is released through a vented flue system, the flames can wrap around the logs in a more realistic pattern. Ventless gas fireplace logs are approved to burn without a venting system. This technology by design is a high efficiency heating product for your unit.


Vented vs Vent Free Gas Log Comparison


Vented logs have been a traditional choice to install in wood burning fireplaces. They are available in various sizes, the most common being 18", 24" and 30". A 42" fireplace opening will typically use a 24" log set. Vented logs are aesthetically appealing but relatively inefficient. Vented logs can be installed in a natural or liquid propane (LP) gas application. A standing pilot flame is required for LP gas but is optional for natural gas. Glass fireplace doors need to be completely open when burning vented logs.


At a 99.9% efficiency rating, realistic, ventless logs are the cleanest burning technology. All vent free logs contain an oxygen depletion sensor for safety. Because particles of combustion are distributed back into the room, glass doors need to be completely open when burning vent free logs. They are available in sizes from 18"- 30" wide with the most common sizes being 18" and 24". They are compatible for both natural and liquid propane (LP) gas. A battery-operated remote is available for both a standing pilot flame and an intermittent pilot ignition (IPI) system.
