Vented on Vent Free Logs?

Vented and vent-free gas logs can be professionally installed in most masonry or factory-built wood burning fireplaces as long as the fireplace and chimney are in good shape, and natural gas or propane gas is available. While vent- free gas log sets require careful consideration in sizing, they also provide more installation options

Have all Chimney's inspected by a licensed Chimney Seewp is highly recommended before installing any Gas Log Sets.

SELECTING A GAS LOG SET Much like any other appliance, it is important to spend the time to choose the gas log set that fits your needs.

Do you want a realistic looking, wood fire substitute? Are you more interested in the most efficient way to heat your home? Here are some facts that should help you choose between a vented or vent free gas log set.

Vented Gas Logs:

* These logs must be installed in a fireplace with a fully functional chimney, to draft the smoke and combustion gases from your home. * These log sets have been available for over 50 years and are still the most popular. * Vented logs are the logs that most resemble a realistic wood fire. * They use an open damper, which limits heating efficiency. Just like burning a wood fire, most heat escapes the chimney and only a small amount is returned to your home. * Vented log sets are more flexible. Logs can be repositioned according to preference.

Vent Free Gas Logs: (Non-Vented)

* Vent Free(also known as non-vented, unvented or ventless)logs do not require a chimney. * They keep 99 percent of the heat produced in your home, and are very efficient as a primary heat source. * All units are equipped with an ODS (Oxygen Depletion Sensor). This device cuts the flame off if the oxygen level in the air drops below a safe level. This situation is very rare. * Vent Free logs cannot be repositioned once they are installed. This is due to vent free log sets having to maintain a complete clean burn which requires the logs to sit on the grate in only one way. * Some states (California, Massachusetts, and a few others) require special permits in order to operate non-vented appliances indoors. It is the customer's responsibility to know his or her local codes and limitations.

With a vented gas log set, the damper must remain open when in use. To reduce heat loss, it is a good idea to install a set of glass doors to close off the firebox when the logs are not in use. Vent-free gas logs are designed to operate with the damper closed.
