Can I burn unvented logs in my wood-burning fireplace?
No. Doing so will void the warranty on your fireplace and possibly void your homeowners insurance. An unvented gas log set that complies with the ANSI Z21.60 standard as a vented gas log set can be used as long as the damper is removed from the unit, but any other type of unvented log set will cause hazardous conditions.
