How do I know if my gas logs are vented or vent free?
- Inspect the logs. All vent-free logs are firmly attached to a U-shaped burner and cannot be moved.
- Follow the gas line from beneath the logs to where it disappears in the wall or floor. If the gas is merely contained by a simple gas line, then the logs are vent free.
- Turn on the fireplace.
Also question is, does a gas log fireplace need to be vented?
Just like a traditional wood-burning fire, vented gas logs produce carbon monoxide emissions. For this reason, they require a chimney or flue to operate. You must remember to open the damper each time you use your unit to allow for proper venting.
One may also ask, which is better ventless or vented gas fireplace? Ventless fireplaces are more energy efficient than vented fireplaces because no heat escapes up the flue, so you'll save money on gas utility bills. A vented gas fireplace uses more gas to create the same level of warmth because some of its heat escapes through the flue.
Correspondingly, can I put vent free logs in a vented fireplace?
Ventless fireplaces are not designed to have a vent added to them. Your only alternative is to tear out the existing ventless fireplace and replace it with a vented fireplace. You cannot use a vented gas log in a vent-free firepalce, nor can you burn wood in it.
How does a vented gas fireplace work?
