Unburnt pellets

So I had to get several bags of Instant Heat pellets. They burn fine in my EF2, but in my Englander PDVC, I woke up this morning to a pot full of barely chard, incomplete, unburned pellets.
I had the bottom three on 5-4-1, I leave the heat/blower on 9-9 because I have it on tstat.
Any tips on what numbers I should try using these pellets, or what to do.

I don't know what factory settings are for PDVC but you need more air. Increase LBA so it's 2 or 3 numbers higher than LFF and it'll be better. So maybe 5-7-1 or perhaps 3-5-1.

Most likely an airflow issue. This is usually accompanied with a thisk, black sooty build-up on the inside of the stove and clearly visable on the glass. May also want to check all gaskets and also make sure that you do not have a clog in the pipe somewhere. Good luck.

I'll try 3-5-1 see what happens.

For whatever sense it makes. the glass is less dirty than with burning barefoots..

Now thems fighting words.....
But definitely try the new setting.

clean the stoves.

I burn my PDVC @ 551 on 1/3 or 2/4 for more heat
and 441 on 1/2 when not so cold, have not had an unburned pellt issue.
was the door cracked open by chance?
