After running for about 36 hrs and have had the auger assy and pipe taken back apart with no binding or nothing jammed in the pipe , If you hand crank the auger it is a little harder on 1/2 of the rev but not binding, On that harder rev is when the noise is heard by where the motor goes into the gear box, maybe a bearing or shim , bushing?, I do need to replace the connecting rod, rod stud, crank pin and the clutch shaft because they are very worn with alot of play, The connecting rod holes are ovaled Enough to change how many teeth are grabbed,I think i can upgrade to the feed control collar, would it be best to buy an assy? Thanks.......

Hi Sting,,assuming you are not joking, the 'clinkers' from an anthracite coal fire, burning rice size coal,... well the clinker is like fluffy snowball.. and the outer perimeter of the stoker pot is open, there is no shelf or perimeter of refractory for the ashes to sit on,, the ashes fall off the edge of the pot, directly into the ashpan below...

This is much different that burning bituminous coal in an underfeed stoker... even though the stoker mechanism is similar, infact almost interchangable... the anthracite coal rarely clinkers in an EFM,, and if it does,, you just touch the clinker and it falls apart, and into the ashpan..

Here is a couple more pics, My plate exchanger on the boiler in the basement. The 350 is in the garage, and my wireless temp monitor, The 2 probes are in the basement on the supply and return lines and the wireless receiver works within 100 or so feet. Worked great when burning wood so you know when the fire's goin out. Also has alarms that can be set. It is really for a smoker, cooker.......

the clinkers will fall to the bottom and come out with the ashes. A clinker is a ball of fused together ash. I wouldn't worry about it with the EFM.

Is that pex you're using between the two boilers? It looks like standard hot water pex, not meant for heating use.

You need heat pex for heating, with the oxygen barrier. I've never seen it, but it may well be the stuff you are using.

No, that photo is of an EFM 700, it is one of several photos I got from a rebuilder offering it for sale.. Yes it is all rebuilt and looks new..

Two interesting things about this stoker,, the top ring, the perimeter of the burn pot is chain driven to rotate.. I'm not positive if the whole pot rotates.. I think the idea is to keep the ash falling off the edges more evenly, and to keep the feed of fresh coal from below to be spread out evenly.. the way an auger feeds the pot from the bottom it creates a sort of pattern of fresh fuel feeding the fire.. it creates a few warmer/cooler spots.

The other thing is the sideways pointed auger.. the auger feeds coal from beside the stoker instead of from the opposite side of the stoker there is a gearbox changing the rotation of the auger 90*.

Your S20 stoker, 91751 was originally sold to our dealer J W Barto, Pine Grove, PA in Sept. of 1968. It was for a water boiler. This makes your unit 40 years old.
