Hello, I am looking at a used Vermont Castings insert that is being sold for $300. I would be installing the unit into my traditional masonry fireplace. My fireplace has the dimensions of 32"T by 40" wide. I would be looking to heat a 500 sq foot room with vaulted ceilings about 20 ft high.
A few questions:

			A few questions:
- What are the thoughts on this unit from the photos
 - I would be installing a chimney liner. If I were to purchase a 6" liner, then I presume that I'd need to also purchase an 8" to 6" adaptor. Would there be anything else that would be significant to purchase?
 - Are there any suggestions/thoughts that people have?
