The answer may be here some where but I couldn't find it. I have a chance to pick up a new left over pe fp30 ar. I'm pretty sure the ar means it's a series A model. The shop is offering me a pretty good price on it just to move it out. It'll be replacing an old heat n glo em 42 on the main floor of a 2 1/2 story chalet style home. My question is about a heat transfer kit so I can duct heat into the finished basement below. The manual only talks about gravity vents and the powered transfer kit states for B series only. Does anyone know if there's something I can retrofit to make it work on the older model? If I can't it's kind of a deal breaker. Sorry for the long winded first post. Just trying to get away from propane
