I have to clean out the 7 holes in the upper tube every month, and I find unscrewing the square headed bolts to be a pain. Why didn't EFM use standard screws with hex heads so I can use a socket/ratchet? I'll have to find some replacements.
Also, what can I put on the end of the auger feed "square end" so I can attach a drill to it. It takes too long to feed new cold in the pot to start it after pulling it apart.
I can now shut down the boiler, pull the upper pipe/auger, clean out the 7 (nice 4 letter word) holes, put everything back together and restart it in about an hour now. I keep a separate set of tools of this job so I don't have to keep searching for them!
Hate the smell of sulfur when these holes get clogged.
