Dave. Im guessing a bit here. Harman has all of 25 workers. They sold out all their pellet stoves before the end of Oct.
The next delivery date was to Be Jan. I think with that un anticipated demand, a couple of things happened.  They had to vamp up production probably hired more workers, though not skilled to manufacturing Harman stoves. The pellet industry also shares some
same parts for Coal stoves, caught those supplyersby suprise, supplies got depleted.  So substitute suppliers and parts were used.  Stoves are rushed to the market.  All of the above is not a formular for quality. People spent a lot of money for advertised quality As more disgruntled owners post here. Revealing like you, preformance not up to expectations, Dealer techs lacking, No help from Harman,
Issues get un resolved.  I would be my advice to wait before purchasing a new Harman and monitor how all this plays out. Either that, get your deposit back and purchase another brand that is less problematic. Harman could turn out to be, the best reson for getting a Qudrafire Pellet stove

I can vouch for what Elk just commented on as my coal stove dealer just got back from NEPA. He went to pick up 2 stoves at Keystoker. The sent him the wrong stoves and his customers already paid for them in Sept. When he went into the shop, he saw about 200 “shells” of stoves sitting there. They all were waiting for electronics. Their supplier got hit with massive orders and they did not have the parts. I beleive the stove mfgs. get a lot of their parts from the same folks. So Elks premise may be correct.

Elk,
I never saw 1 post by jsparkz having issue with the quality & performance of the Harman P68, just questions regarding operation. Does it pump out heat?

Getting back to your original post.  It seems Harman is taking quite a few hits in the Pr and QC departments. So much for that gold warranty plan, when the guy doing the trouble shooting does not know his A** from his Elbow.  BTW I wished you had posted it was taking in a direct air feed. Would have saved me some typing. However it would not be the first time this situation existed

I said it once and I will say it again...Harman has one of the best warranties out their and they do use it. However, if they are not being told that there are specific problems by the dealers “fixing” the unit then how can they put their warranty into action. I think the dealer(s) need to step up and call Harman on the issue at hand and specifically ask Harman if this issue will be under warranty. From what I understand they are not told this by many dealers that are in the field. In fact they don’t find out about it until things like this are already in circulation.
I agree that there are issues with QC but most times your hear of noisy BLOWERS and MOTORS, items that Harman does not Manufacture… I also heard that they are getting hit hard becuase of this. just something for yall to think about.

Part of the problem is the expectation You bought a BMW only to find it runs like a Hyundai. Bad analogy, Hyundai has the best warranty in the business.  People paid more to purchase a Harman, when a Cheap Charlie would still heat the same area for thousands less. They expected more or not to be having issues, issues that go un-resolved and drag on.  I understand blower noise. If you bought new house from me. You do not want to hear I hired a poor tile man it’s not my problem. You want a less than acceptable job corrected.  Actually it would be negligent of me, not to have discovered the poor tile job first and had it corrected before it was an issue. 
That’s quality control, not letting the consumer find your problems, then have the dealer try to figure them out for you.  Quality control begins by buying decent components. testing them out. before you install them and have the consumers complain. Unfortunately this does not happen there is a rush to the market and fixes arrive afterwards Can I say Microsoft

Well Elk has a valid point with the ramping up demand and filliing labor with less skilled and qualified.  Maybe just jumped on bandwagon a little to late. But as pelletheat states technically it runs and throws out heat and how do you know if it’s operating as efficiently as it could or should when nobody knows what it’s potential was when designed.  It definetly isn’t all the dealer made it out to be unless you have an unlimited supply of free pellets then you could heat a factory with it. But how is one to know when the factory won’t talk to you and the dealer(other than being a great salesman) has no actual working knowledge of the product and seems to to just blow you off because he has your money and not the next guy’s in his showroom lookin.
Well I moved the stat upstairs today and switched to room temp.  The length is farther than recommended but not over the max 100’.  So far the stove seems to either give it all it’s got or shuts the fan off one extreme or the other which is why I had originally switched to controlling it with stove temp setting at least it was even heat and distribution blower always ran(regardless of how the manual says it operates).  But I’ll give it some time and see what happens.

POUR THE PELLETS TO IT!!!!!! It’s only money and the pellets are so readily available.............................
