How are vented gas logs different from ventless gas logs?
The primary difference is that ventless gas logs can be operated with the chimney damper closed, which keeps significantly more heat in your home while vented gas logs operate with the damper open to produce a flame that looks more similar to a real wood fire flame. Basically, ventless gas logs provide more warmth than ambiance and vented gas logs provide a more realistic flame with stronger ambient firelight.
