Ready for Spring Nor'easter - Installed a Harman Pellet Stove Today

Some pics. More to come once I get some pellets in there and fire her up so you can see how she's behaving

 

On the direct drive stove the auger motor turns clockwise because the front of the motor faces in towards the front of the stove. On the chain drive units the front of the auger motor faces out toward the back of the stove so it must turn Counter Clockwise to make the front of the auger still turn clockwise. Does that make sense? The magnet can be flipped to make the motor turn either way but Harman sells an OEM CCW motor for a few extra dollars.

 

Hey Corkman
Do you have the new fluted burn pot or the older burn pot in 2004 and below stoves?
I put the new flutie in mine and stove heats better!

Yeah that makes sense as you can see in the pics I have s chain drive and the front of the auger motor is facing toward the back of the stove. Old style butn pot is my guess

 

yea, the DDM will tell us which board you have, what the settings are on the board as well.......dare I ask for a draft reading on the cold stove?

 

ooooh....an old B revision board.....let me check out the settings for the Advance for that board and get back to you.....all your switches are the same......should be easy!

 

I will get a draft reading tinight

 

00000000 all off on the board is correct for that model stove.......be forewarned, you wont find that board again, and the new board WILL NOT have the same settings!

 

High draft is about .88 and low is .78 and low draft adjustment is at 00volts

 

So, you haven't adjusted low draft downwards then, right? (if you did, the low draft would be reading a reduction in voltage of the combustion fan)....if you can, try lowering the voltage somewhat, but ith your board, I don't think you can lower it much more than 10 volts anyhow....new ones are more)

 

so, a couple things.....with a high draft, its likely you are losing heat up the chimney. When its burning lousy, whats the ESP reading on your DDM? Is it reading a true reading? If the stove is cold, what is it reading (I am suggesting testing both the board and ESP to make sure all is kosher)....

Also, pull the slide plate...is the bottom clean? Is anything on the inside of the feeder weldment (gunk) restricting the flow of pellets?

Does it seem like the stove is feeding a lot, but youre not getting many pellets, or are you seeing a lot of pellets burning, just not much heat?

 

I havnt touched the low draft. You are correct in that it will only adjust 10v.i removed the slide plate and there is nothing on it. Fines box had minor amount of sawdust but I vac it out and while the area was open I blasted it with compressor and reassembled. Put some pellets in and fired it up. The startup feed lasted 3 mins 40 secs. I thought it was only supposed to be 3 mins but I could be wrong on that. Saw sparks flying at 1 min 30 sec and had fire at 5 mins 10 secs. Room blower came on at 7 mins 20sec. On low 1st but gradually increased to high. There seems to be a noticeable difference in the pellet feed and the fire now for some reason. I started it in room temp auto,feed 4 and set temp to 70deg. Ddm was showing that the room sensor was showing the basement was 57deg before I started stove. It took about 1hr 15 mins to get it up to temp and basement is 1,100 sqft fully finished with insulation. I had a much bigger fire than I'm used to seeing and I could clearly see the fire being pushed forward as the pellets were being fed so something happened when I played with the feeder and the fines box. Fire is def bigger but has a strange action to it every so often almost as though air is blowing across it causing it to almost wobble and change color from white flames to almost orangish. Thes pics show what the stove was doing while burning at said settings

 

I switched it to manual so it would go to maintenance burn. It's been there for about 30 mins now. I still havnt adjusted low draft but will shortly. Interesting that the draft meter shows a higher reading. DDM is showing that combustion blower is running at 93v while in maintenance burn

 

Interesting observation. So I went ahead and adjusted the voltage down the full 10v. I took it off maintenance burn by turning dial up to 75 from 70 and stove began to ramp up. My combustion blower is running at 114v instead of the usual 119v. I didn't think adjusting the low draft had any effect on how the stove would burn on high

 

possibly by monkeying around with the feeder weldment cover you fixed it? If its leaking air (?) it can break vacuum, causing your feeder not to run, thusly giving less heat, since the fuel isnt there when you really want it to be.

As for setting draft, low draft is only set on a COLD stove! You cant set high draft at all. And yea, your combustion blower will vary voltage-wise. Everything else sounds like its running ok....face it....maybe you fixed it!

 

I shut it down last night before I went to bed so I will check low draft s little later.im thinking back to when I bought this a couple yrs ago. Stove had sat for quiet some time as the owner was actually in Iraq. It wouldn't run when i went to look at it but I bought if anyways because the price was right and it's a Harman. When I got it home I emptied out the hopper and pellets were damp at bottom of the hopper. I pulled auger and installed crossover tube and blasted everything with compressor. I'm wondering if some of the damp stuff was still lodged in there in an area I didn't hit.ive removed the sliding plate numerous times in the past 2 years when vacuuming out the fines box and fire never changed. I think hitting it with the compressor did something and Ty for pointing me in the right direction lousyweather. Much appreciated. We have some lousy weather here today so once I set the low draft I will fire her up later. Thanks again

 

yea, Cork, it does sound like you have done pretty much everything right, far as I can tell. You could always pull the auger out for fun and look up into the feeder weldment from the rear to see if any schmutz is up there.....

 

I may just do tha

I may jus do that for peace of mind. It's definately burning a lot better whatever I did. New low draft reading is at .47 since i adjusted down -10v
