We bought a Harman DVC-500 direct vent coal stoker a couple weeks ago, but just finally got it up and running due to a faulty circuit board / temperature probe.
Apparently the temperature probe, that determines if the hopper temperature is too hot, was whacked. It is supposed to indicate when the hopper is too hot, and if so, run the feed motor basically non-stop, to get the coal out of the hopper and into the box - so any fire is in the box and not the hopper. Makes sense, except our probe was saying that it was too hot even when it was not running - so the feed motor was always running. We had a crazy fire the first night and I stayed up all night waiting for it to go out. We shoveled out all of the coal from the hopper and just let it feed everything in to die out.
Anyway - we got a new circuit board put in and still had trouble. Only when the tech put in a new temperature probe did it begin to work properly. So yesterday was our first day of running the stove.
I was nervous in the first place to have a box of fire in my living room, and then with the trouble we had it made me more nervous. Knowing that our stove is fixed, I feel much better and didn't have trouble sleeping last night (first night the stove was on). But I'm still leery of leaving the house with it on.
Were you guys nervous the first time you left the house with your stove on? It's been running for 24 hours now...we've got it figured out (so far) so that it's about 72 in the downstairs and about 67 upstairs (nice!). So it seems to be fine. I guess I just need to get my foot out the door and go for a quick trip somewhere so I get over this initial worry.
Also - I read that a few other people had issues with their Harman DVC-500 from the start. Was your problem the same as my problem? One guy said that his was from a bad year. How would I know if mine was from that year - or if I should anticipate any other problems?
Thanks for your help. I already do love this stove and I know I will love it more when I don't see the Petro man every month with a $600 bill.
