Thanks for any help! We have an ivory Jotul 3TD in our living room -- stainless steel liner up pre-fab fireplace -- vermiculite insulation. The former fireplace is bricked up except for the exiting pipe, and all has gone well for two years. However, we wish the Jotul 3 were a little bigger, more efficient, and required less temp monitoring. I just bought a 1987 sand enamel VC Defiant Encore in unbelieveable condition -- not a chip on it -- gaskets look new, glass clear, catalyst perfect, etc. It was installed in a small basement family room, and my guess is that the owners regretted the decision and used it just a few times -- too much stove for the space, downstairs. I've checked our clearances, and the Defiant would meet code where our current stove is. A few questions: Would it be okay to run the 8" pipe that came with the stove to an 8" to 6" adapter, and up? I have read conflicting opinions about this, and noticed that VC sold an optional (and may still sell) 6" adapter for this stove. We wouldn't be operating it with the doors open, which I have heard would make backpuffing more likely with a 6" chimney. Would you recommend a different stove? I like the Jotul Oslo, and the Castine less, but we'd be buying those new, and the sticker prices are up there. Anybody know the likely efficiency of the Jotul 3TD? Thoughts? Thanks!
