I saw that post Don. Chimneys get fickle when there is a cold night followed by a warm day.

Continuing my practice of accomplishing very little lately I still am running summer settings and the boiler badly needs a cleaning. But at least I have lots of rice on hand.

Outfire!!!!
Got some Buck from American Coal today and ran it into the bin, was messing around with the baro, if I open it all the way I can look into the horizontal smoke pipe and check the ash buildup. I KNOW the flap was fine and moving when I left it.
2 hours later I'm in the kitchen and the hot water is just warm. Boiler's out, baro flap stuck wide open. I know there are previous occupants here that still float around the place and stir up trouble, but please stop screwing with my boiler!
Hand-fed still burning as well just 'cause.

That's not bad, looks like you go two years without problems! :)

Did you bump up the feed rate for the Buck? If the feed rate is a little low it won't hold a fire as well.

I've burned buck in the past, Bob was out of rice so I had to get buck. It's OK on the feed rate, but I did up the air just a tad.

You had to say that!!!
Broke one last week, dug down to the auger in the bin and cranked it backwards and got it emptied and freed up, no obvious reasons why it broke a pin.
Last night it broke another one, so there is an obvious issue, and I got to shovelin' out the bin.
Well the bin pipe has lost about 2", and what's left of it ain't so good. It's thin, the I.D. is now much larger then it's supposed to be. That would account for the broken pins. The coupler and the tube to the pot seem to be fine. When I pulled the pot auger out the bushing fell out too, it's very worn. The auger looks fine, no sharp edges at all, I was surprised. So it's down for the count right now, so I decided to fire the oil hot water heater that I haven't used since 2011, it's been drained, but there must have been some water laying in the bottom, it leaks like a sieve. Anyone want an Aero 30 gallon oil-fired low boy that needs a tank? Oil burner works fine, I don't think it's worth it for me to replace the tank right now.
This is the first repair I've had to do on this unit, and it's been in use continuously since I installed it, that's not too bad!

When I assembled the EFM every part that had threads or pushed together got slathered with anti seize compound.

The bin tube was really disintegrated inside the coupler.

WOW! That stuff really got rusted to death. Thank goodness for Anti-seize!

Indeed. I have a vacuum system to fill the EFM bin, unless I dampen the coal it creates a lot of dust.
The next time I should use stainless steel, it's worth the $. But it was almost 9 and a half years as well.

The 4 bolts unscrewed, the coupler came off of the aluminum pot auger tube after a few whacks with a mallet. I had to use the fire wrench to heat up the assembly to get the steel bin tube out. Everything went back together with a generous application of anti-seize compound.
