The main problem with Harman is trying to get a hold of them to talk with someone other than the dealer about problems. Very frustrating.


Harman does not have a customer service. The person you talk to is your dealer.

Would like to hear HHT's response, although IMO it's just the nature of the beast for the most part.

As far as the clips go, on one hand, I'm thinkin why would Harman sell them if they're not effective? On the other hand, I think if they're effective, why doesn't Harman use them to begin with if it mitigates the problem.


The response would be to clean the glass daily.

I have the same issue, as long as it keeps throwing the great heat the glass does not bother me. I wouldnt mind having a clean glass all the time. I know with the Somersets I'm burning now has been the worst the glass has been. If you look at the pic in my profile you can see a little bit of the ash on the glass. I was burning OMalleys than and that was taken three days after I cleaned it. I think the biggest issue is the type of pellets ur burning.
 
I'll take a pic of my glass tomorrow when I clean it.

Well that would certainly solve the issue :)

Eric, have you any experience with the elusive "improved" clips? Mine never gets dirty enough to bother me much between cleanings, but I feel for the other posters. If I had an XXV I'd definitely be looking at it more than my mini workhorse.

I paid very high price for the XXV & the large glass was one of the features I liked. I could have gotten a Brown enameled Quadrafire Mt. Vernon AE for $800 less like my XXV. At the store the display XXV glass was clean even though the dealer said it had run for about 4 days. If I would have known of this issue I would have purchased the Quadrafire that I went to buy but I liked the feed/burn system of the Harman better. Very disappointing after paying premium price for the stove. No issues with heat output & looks of the stove.
 
Harman has a Facebook page.... as Eric says Harman wants you to go to your dealer...1st....... I understand that the glass is no big deal to some but to others and for the price of the stove, I'd like to see the flame..
 
From what I have been able to gather, the air reducer as you call it is NOT what it seems. The air for the air wash comes from the left side of the stove and if you take the rake out, the air comes out stronger through the left side holes. The rake diffuses the air allowing it to come out evenly across the horizontal section and up straight as apposed to a sharper angle as you are seeing with your pics
 
So here are some pictures I took before cleaning my stove today. The first picture is of the glass, I been burning Somersets all week. The second picture is the burn pot and the third is the ash pan.

all fairly typical for the useage....needs cleaning, but nothing untoward here (the pics)
 
wire your glass and scrap your burn pot daily. I have yet to scrape or wipe my glass in three weeks on my Mt Vernon and I made a post yesterday about that.

Eric
 
I scrap my burn pot every morning except today due to weekly cleaning. It's overkill to me to clean the glass every day

Turn the feed rate up. 2.5 is to low. What kind of pellets you burning? I started at 4 and dialed it down using the 1 inch rule. It's set at a little over 3.5 with the t-stat at 73.

As far as the glass, I believe it's the brand of pellets you burn. Green teams did a black-out on my glass after 3 bags last year. Why pay 285 for that when I can get Vermonts, Northern, or Spruce Pointe for the same price and I can enjoy my fire.
Well I did the Harman test for 1" of ash...Started with 4 on feed, Stove Temp mode, High fan setting, Heat setting on 7...30 minutes later over the edge with hot coals, continued going down in feed every 30 minutes & not until I got to 2.5 on feed rate did I get a ash line about 1". Using Magic Spark pellets from Menards.
 
I feel the Somersets are burning way to dirty. I have the feed set at 4 and the temp set at 70 on room temp auto.
It's funny because last year in our area (Michigan) Somersets were the best I'd burned. This year I got a ton when Menards had them & I burned a few broken bags & didn't think they burned as well as last year. Could have been the open bags I burned absorbed some moisture but will find out when the ton of Magic Sparks run out & I get into the Somersets. Wish we had a better choice of pellets especially those made from Pine, which you would think in Michigan we would have an abundance!
 
My glass clouds up identical to Chevys, and I have seen numerous posts with the same pattern. I think it is pretty much what to expect with a Harman.

I don't know if it is related, but if you notice on the inside of the stove above the glass/door, there is a lip that catches a lot of ash, possibly cleaning that often, might lessen the build up on the window.

How are those Turmans burning? I have a Harman XXV this is my second season wit it. I tried the Turmans last year and my stove hated them. I came downstairs one morning & my stove had shut down. It was the pellets. They were way to long and formed a bridge blocking pellets to feed causing it to shut down. The Turmans got great reviews but they don't do well in my stove. The heat was nothing great. I've tried a bunch of brands that supposedly throw a bunch of heat. The only ones that make a difference has been Barefoots. My XXV loves them. As far as your glass my stove does the same thing. It doesn't matter what pellets you burn. Most stoves have a way to mess with the air intake. Harmans don't. Set in factory.

My stove loves barefoots too and has a big crush on Maine Woods (softwoods right now but also like hardwoods). However, we clean the stove, ignitor, glass, etc every week, and the glass gets sooty just like the OP's within an hour or so. I don't want to clean the glass every day. :(
 
I cleaned the XXV again this Weds. and had a full ash pan again for a weeks burning. I have to set my feed around 2 or the burning pellets just push off the edge. It has been this way with all pellets I've tried with only a change of from 2 to 2.5 on feed rate. I I did try starting on Stove temp mode at a high range & the glass stayed clean for about 2 hours! At least improvement! By the patterns I see on the glass I'm just about positive it is a air wash problem with too little air getting to the dirty spots on the glass. Extended my room probe by 10' with some 18-2 thermostat wire & put into next room near Fuel Oil furnace t-stat.& that helps when running in Room temp mode.
 
another thing to look at is what is the setting on the combustion blower? You need a DDM to know. I had a PF100 that we adjusted the combustion blower turning down it's voltage. The customer reported that at feed rate #3 it was pushing unburnt pellets off the burn pot. He scaled the feed rate to 2.2 or so and it took care of the issue.

I had a problem with burning/unburnt pellets getting pushed off when the stove was fairly new. I researched here and the manual and decided to clean out behind the plate below the burnpot where the ignitors are - worked perfectly and I added that to my weekly routine, no more panicking pellets.
 
I clean out the area where the ignitor is too but no difference. A lot of people on here say that's not right my feed rate is so low but I've come to the conclusion its OK or why do they have 1-6 range! Learning curve but still appreciate the input from everyone.
 
I also have an XXV and found that I needed to replace the door gasket at the beginning of year 3. A tight door has a big impact on the dirty glass pattern.....I failed the dollar bill test....but didn't recognize until we lost power and really saw where the leaks were.
