What is vent-free?
Vent-free means there is no need to install a vent to the outside, no chimney, no hole in the roof or wall. All you need is access to a gas line, so you can place a vent-free gas appliance just about anywhere. There are two common vent-free gas appliances used in homes, gas ranges and gas dryers, so vent-free is not anything new or unusual.

-
Every vent-free product sold in the U.S. comes with a precision engineered Oxygen Detection Safety-pilot (ODS).
-
The ODS automatically reacts to a reduction in the room's oxygen supply, and if the oxygen level approaches 18%, the ODS shuts off the gas, eliminating any possibility of danger well before an unsafe level is approached. The appliance can only be re-ignited manually and only when the air is back to normal.
-
According to ODS manufacturers, no documented deaths have been attributed to emissions from an ODS- equipped product. With more than nine million vent free units operating in American homes and more than 50 million world-wide, that is an exemplary safety record.
