Clean Burning Vent-free Gas Logs

Vent free gas logs, also called ventless or unvented gas logs, are designed to burn the fuel gas 99.9% completely. This means that they burn “clean”. Any combustion byproduct is so minute that typical air turnover in the home washes it out, although home ventilation is important with any type of gas product. You can burn this appliance in your fireplace with the damper closed and allow the heat generated to warm the room, in most cases.

In order to perform safely, building codes limit vent-free appliances to 40,000 BTUs maximum in common areas of a home. Units are required to have an Oxygen Depletion Sensor (ODS) with a safety pilot control, meet emissions standards, have minimal flame impingement, and meet clearance to any combustible material (like wood) – we will be happy to explain all of this to you.

Vent-free Gas Log Facts

  • Your fireplace must be inspected by a certified chimney sweep before you install any gas log set
  • Vent-free gas logs are for supplemental and emergency heat only
  • Available in natural or propane gas, some models can use a remote, wall switch, thermostat remote, and other accessories
  • Combustion air is drawn from the room
  • Vent-free does not mean odor-free (logs don’t stink, dirty fireplaces do!)
  • Vent-free appliances cannot be installed in a bedroom, bathroom, or any area considered to a ‘confined space’, unless approved for such application
  • Vent-free gas logs must be installed in an approved vent-free firebox or operational wood-burning fireplace
  • Vent-free logs are placed in a fixed position when installed; they are not movable by the user
  • All models at Future Energy come with a safety pilot system, Oxygen Depletion Sensor (ODS), and lava rock for the floor of the fireplace
