Just an FYI if anyone’s looking to buy these this year. These have been one of my favorite pellets in my Lennox pi40 but not this year. I’m not sure what happened as opposed to years past but, they’r dirty and my room temp dropped 2 degrees when they replaced the indek pellets in the hopper. Just to make sure I swapped back and stove temps were back up. To bad cause even though more expensive they were always worth it.
