Hello This was new last year (2018) It is added to cover the bottom of the burnpot to break up clinkers. Has anyone tried it?
Wow. Just wow. I have a St Croix, and while some pellets cause more clinkers than others, I have never had a problem with them. A quick scrape once a day takes care of it, ( that's when I used to burn 24 hours a day. ) Now I use it just to take out a chill, or if we're going to be downstairs, and clinkers aren't even an issue. Buying a bag of what looks like crushed up lava rocks from a gas grill sounds like extreme overkill to me.
Geez...I've never had a clinker in my current stove since 2006. I did own a St Croix corn burner and clinkers was it's middle name.
I found that the size of the holes in the shaker grate are 3/32” diameter are small for wood pellets but work for corn. If burning wood pellets then 1/4” diameter is best and drilling every other row out to 1/4” helps. It would be nice to have a wood pellet shaker grate. What do you think?
We've been running a used Prescott EXP (2004 vintage) since 2014 with many different brands of cheap pellets. Never seen a clinker and this is the primary heater so it runs a lot. Scrape burn pot once a week at most, so I'll pass on the firepot stones thankfully.
