Do not buy these pellets. I'm cleaning my Accentra 52I every 200 lbs. Just cleaned it Top to bottom front to back. 200lbs ago now I'm back to am lazy flame low heat and tons of ash. Nearly 4 gallons of ash from 200 lbs. I'm doing a full clean on it tomorrow after work. Hardly a pellet over half an inch long most average 3/8 inch long. My glass is sooted up within 24 hours. Gone through 3.5 tons of misery this season. I'll pay to run the heat pump next year if these are the only pellets my Local Menards can get. Run AWAY from Indeck!
