Use the scraper that came with the stove for walls and heat exchangers but the burnpot needs something a bit more rugged.tundraSQ said:TedNH said:I got my stove figured out.
SCRAPE YOUR BURN POT.
And I mean GOOD.
I had big chunks of carbon stuck to the SIDES of the pot. Now the fire looks like a blow torch and its throwing some mean heat.
I just did this..I had been cleaning the front of the burnpot....tonight I let the fire die down and REALLY got deep down and cleaned it all out...I had no idea the back and the sides would need to be cleaned. This is a learning process...but I ran the stove for 2 days without touching a single setting...
thanks
Just a tip Every day when I get home from work I give a quick but strong scrape of the back of the burnpot, Just to keep the carbon from really building up (it only takes a minute and the stove is still running when I do this)
On the advance the major buildup is always on the left hand side of the burnpot and the glass always fogs on that side first.
There seems to be a bunch of 25 owners here.... What side is worse for clinkers and which is worse for the glass fogging up?
Left side for me had the most build up...and I was thinking as I was scraping it..."there MUST" be a better tool for this"...and the right side and top of my glass fogs worst.
