I'm looking at installing a VC Aspen into a clay tile lined masonry chimney. I need a bit of help before I get in over my head. It will be a hearth installation into a long unused fireplace that had the firebox painted (latex). With the radiant properties of the stove, will this create a problem- i.e.-should I strip?? Also, assuming I am using double wall stainless steel to vent through the top of the existing chimney, can anyone give me a rough estimate on what to expect financially for a professional installation (so I can try to get the pre-approval from my CFO wife!). Approx. 18-20 feet (1.5 stories). Thanks for any help you can give.
