My wife and I like the looks of the quad 7100 and was wondering if I could get some feedback from some actual owners of this zero clearance unit. I have a price quote of 3600 before taxes on it and was told the class A pipe would run around a grand plus 500 for instalation. Does that seem like a good price? Also what did you owners place this in, a stone or brick masonry fireplace or build a chase around it. I love the looks of the natural stone or even brick for a fireplace but know that comes with a big price. We were thinking of just having masonry up to the mantel and then just drywall above that with some imitation stuff to match. Did anyone that owns this unit instal the vents if so how good does it work. We have settled on a 2500 sq ft floorplan thats fairly open. thanks
