The reason for this is that they do not burn the gas cleanly and create exhaust that is very similar to burning a real wood fire. This than
ventless logs which makes them look far more realistic. The downside is that most of the heat goes right up the chimney.
However, In most cases, you can offset this heat loss by slightly closing the damper...but you must be careful that the exhaust from
your logs is not coming into the room because, just like burning real wood, it contains Carbon Monoxide. A good way to test this is to
turn on your gas logs with the damper slightly closed. Hold a lighter or candle in front of the fireplace opening near the top. If the flame
from the lighter (candle) is being drawn in toward the fireplace, then you are OK. If the flame is standing still or pushed out toward the
room, then your fireplace is not drafting enough and you must open the damper more.
