What is the difference between Vent-Free and Vented gas logs?
Vent-Free logs are designed to be room heaters. Unlike vented log sets, with Vent-Free you can keep your damper closed and force the heat into the room rather than letting it go out the chimney. Q: What is an ODS (oxygen depletion sensor)? A: An ODS is a sophisticated standing pilot system, standard on all vent-free logs. The ODS will shut off the log set if the oxygen level in the room falls below 18%. Normal oxygen levels in a room are around 21%. Oxygen depletion sensors have been used for over 40 years with a 100% safety record therefore making them a very safe and reliable system.
