Time to call the place where you bought it and have them send someone out.

from the 70's up through the early 90's home construction made significant leaps and bounds. In the 70's if you took all the air leaks in a home and added them together you would end up with approx. a 3' diameter hole in your wall! Todays construction however is so tight if added all the leaks it would amount to approx. a 3" diameter hole BIG difference. Also in the envelope of the home you have all these appliances taking air out of the home. Dryers, ventahoods, CH/A, and yes even the fireplace just to name a few and nothing is bringing air in so eventually you end up with a negative preassure in the home or a vaccumm if you will and the home will take a breath where ever it can. Because of this hearth designers and manufacturers have come up with outside combustion air kits to offset the negative preassure sometimes its not enough to overcome it but does help in the efficency if the home is really tight. Hope this information aids you in your querry

My Harmon P68 is a piece of junk! My first stove was an Englander, a cheap pellet stove purchased at Home Depot. The Englander worked great. My Dad got one after seeing mine, his works great. After using the Englander I "upgraded" to a Harmon P68, that was a mistake. I saved up $3500, got rid of the Englander, ordered the Harmon P68 in Dec 2010, installed it in Jan 2011. After installation the feed motor needed replacing. So I couldn't use the stove for a week. Harmon sent the wrong part so I had to wait an additional week. The Dealer/installer was apologetic and not happy. I was starting to regret this stove swap. The stove worked great after that. Fast forward to Feb 2012. The blower motor is making a thunking noise and occasionally screeches like a train whistle. The warranty has expired. Remember, I ordered it in Dec it was installed in Jan and it didn't start working until 2 weeks after installation. But it's a week and a half since its first firing and Harmon doesn't want to fix it. The Dealer/Installer is an older guy that's been selling and installing stoves for 25 years. He's seems as upset about this as I am. He told me Harmon used to back their stoves with a longer warranty but another company purchased the name and now it's just 2 years. He also said he used to be proud of the Harmon stoves because they used to be built better. He said the original stoves used to go 5 years or longer before needing motors replaced. He told me that he's done with Harmon. Probably feels a little guilty that he didn't tell me this when I purchased my junk Harmon. So I'm going to replace my blower motor, the 2nd stove motor in 2 years. And I'm going to start saving up for a new stove. Not sure which brand but it won't be a Harmon. If you want to pay an extra $1000-$1500 for a name on a stove that might or might not work out of the box. That'll probably need expensive repairs and replacement parts soon after the warranty expires. Go ahead and buy the unreliable Harmon P68! It looks nice but it won't heat your house.

I've had my Harman xxv stove for 4 years now and I HATE it, every year it has to be worked on and service calls are $100. just to come out... there for I would NOT recommend anyone buy one of these crappy stoves, you would think for the price I paid $3,000. that it would work .... just buy a real wood stove !!!!
