Okay i am stumped. I bought a harman p35i insert last December. It ran fine till it was time to shut it down. I burnt 2 tons in it. I did A thorough cleaning on everything the manual says even the exhaust chimney. Now I’m starting it back up. I have it on room temp and the feed rate at #4. There isn’t much of a flame. Maybe only two inches. I double tripled checked to make sure everything was clean and put back correct. I just don’t understand why it’s acting up now. It only has 2 tons of pellets through it. Any help would be great.
