GAS LOGS

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 and richer flame.  Because the combustion is released through a vented flue system, the flames can wrap around the logs in a more realistic pattern.  Vent free gas logs are approved to burn without a venting system.  This technology by design is a high efficiency heating product for your fireplace. 

 

Vented vs Vent Free Gas Log Comparison


VENTED GAS LOGS

Vented logs have been a traditional choice to install in wood burning fireplaces.  They are available in sizes from 12" to 120" wide with the most common sizes being 18", 24" and 30".  A 42" fireplace opening will typically use a 24" log set.  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 an optional feature for natural gas.  Fireplace glass doors need to be completely open while burning vented logs.  Vented logs are aesthetically appealing but relatively inefficient.

VENT FREE GAS LOGS

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