Fire Logs-To Vent or Not To Vent

What does it mean to have vented or vent-free gas logs? Vented logs use a chimney (damper stays open) to allow an outlet for heat and the byproducts of combustion to escape. Vent-Free (damper stays closed) means there is no chimney (or vent pipe) used in the operation of the appliance, so the heat stays in your living room. A vent-free application is 100% fuel efficient and serves as the principle heat source for the room it operates in. As an added bonus, you can know you'll stay toasty warm if the power goes out some cold winter evening.

Is vent-free safe? These systems have been used safely for over 35 years in the United States. All of our vent-free gas logs have been tested and approved as vent-free room heaters. These appliances are made to burn at a very hot temperature, so the amount of combustion byproducts is much lower than vented gas log systems.

Vented gas log systems are made to look like a natural wood burning fire; and they act like one as well. Vented gas logs burn with a yellow flame, which closely resembles the flames of a natural wood burning fire. This kind of fire produces soot, and a higher amount of combustion byproducts - just like a real wood burning fire. Therefore, a ventilation system (keeping your damper open) is necessary. While much of the heat escapes through the chimney, a good deal of heat is transferred to your house; vented gas log systems are still a smart, environmentally sound supplementary heating method as well as a beautiful decorative addition. You can control the flames and embers by the valve key; talk about decorating efficiently!

Be sure to check local codes before the installation of your appliance. We recommended to our customers that all installations be performed by qualified service technicians.

All vent-free appliances are equipped with an Oxygen Depletion Sensor (ODS) system which will automatically shut off the appliance in the event that the oxygen level in the room drops below the American Gas Association (AGA) allowance. These units operate within industry indoor air quality standards and are design certified by the AGA.
