Yes I have oil forced air furnace that used to be the primary, but once insert was installed, I put the oil on back up status, but always kept it runnable. Had to do a serious service on it last year to get it running again. Did it myself and saved a few hundred bucks. It works good, but stinks, and is too dry LOL. I miss the wood smell. And the heating of everything, rather than just heating the air. Haven't really needed heat yet. I might have to move the oil furnace to the Starting position, and put the Summit on injured reserve till I work this out with PE or not. Its all good, I have heat if needed. BUT WANT WOOD HEAT!! I'm on the road tomorrow, work this past couple weeks picked up. But I plan on taking Corie's number from PE and calling him while on the road. I am kinda glad I don't have to deal with a distributor, and the dealer was more than glad to pass it along to PE ASAP.
