Thanks Dexter. It popped up last night and I emailed right away. It was only about 4 miles down the road from me. I picked it up for $1000. For that price, I'd be foolish not to have bought it. Even came with some (but not all) of the 4" venting I'll need. The original owner has an older farmhouse and upgraded to a Harman PF100. This unit has the updated control board and burnpot, along with all the original receipts and correspondence from Fahrenheit. The direct number for Matt Fitts was written on the front cover of the manual. Hopefully I don't need to call him, but its nice to know someone is there if needed. They build them in Holland, MI which is about 40 miles from my house, so if I ever get into a "parts pinch" I may have the option of making a factory run.
My house is a bit over 1700 square foot on the main level, with a full basement (ranch style). My plan is to tie it into the ductwork. Our house has cathedral ceilings in the living room/kitchen area and heat tends to pool there while the back end of the house (bedrooms) are always a bit cooler. I'm hoping to do away with the fans and having the fan on the oil furnace cycle to move air around the house. Not having a noisy blower in the living room will be a plus too. My wife has her office in the basement and spends a lot of time down there this time of year, so that will hopefully warm up too and get rid of a couple electric heaters. The ductwork isn't insulated unfortunately, but the runs aren't terribly long, and one half of the basement is finished and insulated. The house originally had electric heat. There is electric resistance wire embedded in the plaster and each room had a thermostat. The electric heat had been abandoned when I bought the house, but the thermostats were still there, which I have since removed and plastered over. The house was retrofitted for oil heat at some point in the 70's, as best as I could tell by the date on the original oil furnace I replaced 10 years ago.
There are two big obstacles that I have to get over. First is getting the beast into the basement. I see the rental of an appliance dolly and bribery of steak and beers to get some buddies to help with that task. Second is getting a hole in the foundation wall for the vent. As much as I'd like nothing more than to rip the oil furnace out, it has to stay and I'm not venting into the same flue. So, venting out the east side foundation wall it is, which is on the opposite side of prevailing winds. I haven't yet told my wife that one of the bushes by the side of the house will have to be sacrificed for this to happen. Gotta make room for the spark bucket.
(sorry, couldn't resist)
After that, its a couple backdraft dampers, a bit of ductwork, lots of band aids, some adult beverages and I should be good to go. It sounds so easy when I type it out like that, but I know I'm going to run into all sorts of things once I get into it. This house likes to remind me who's boss every time I start a project.
So far I haven't done anything to it short of remove the hopper extension, vacuum out a huge pile of fines from the hopper, and start giving it a good cleanout. It seems like a pretty straightforward design, but it definitely needs a good cleaning.
No plans to remove the pellet insert upstairs, yet, until I see how the furnace works out. I have a wood eater insert upstairs also, and that is definitely staying so I have heat during power outages (and an excuse to go play with my chainsaws from time to time).
I'll start a new thread with pictures and install info once I get to the fun stuff.
