Don’t have access to a chimney, consider choosing direct vent. These versatile units can exhaust directly out through an exterior wall. They burn natural gases or most commonly wood.
Beware, if you have gas burning factory built fireplace, you may not be able to convert it to wood.
How do I know what type of fireplace I have?
Most are either factory build or masonry. One defining feature is the flue. If you have clay tiles, then you have a masonry fireplace.
