Vent Free Freestanding Gas Stoves
These units typically stand away from the wall and are very similar to a wood burning stove in appearance.
Vent-Free Gas Fireplaces
No chimney systems are required and this product can be used almost anywhere in your home (except in bathroom, bedroom, spa room, mobile home, or recreational vehicle), but provisions for adequate combustion and ventilation must be provided (room size and btu's of appliance are the deciding factors of what btu size can be used for a particular installation).
The appliance uses room air for combustion and exhausts to the room. These appliances are 99.9% efficient and the vent-free burner systems have an ODS pilot system, which ensures that the burner systems will shut down if oxygen in the room falls below acceptable limits.
