Is “Direct Vent” the same thing as “Ventless” or “Ventfree” or “Unvented”?
No. Direct vent fireplaces use a sealed glass front to completely isolate combustion gases and moisture from your home. This is especially important in new construction homes that are built very tightly to comply with today’s energy codes. Ventless, ventfree or unvented fireplaces are designed to expel combustion gases and moisture directly back into the room. Ventless, ventfree or unvented fireplaces and stoves are illegal in many states and municipalities.
