- Hand Fed Coal Furnace: Harman SF3500 reduced down to 3 grates connected to its own plenum

- Other Heating: Noth'in but COAL! Well, Maybe a little tiny bit of wood
Welcome to the forum.
I'm pretty sure they are the same motor, so you can't. I'm not sure why you would want to. If you run the combustion blower without the feed motor you will just burn all the coal on the grate and risk a hopper fire.

Is this one motor w/ two shafts?, like *SD* suspects.

Then the feed rate could be too low. After a 30 minute continuous run you should see fire down the whole grate and about an inch and a half of ash on the end. If you have more ash than that, the feed rate is too low.

This photo is after burning about 30 mins on high. I notice if I turn it down much in the guys makeshift rheostat (our of a dimmer light switch. It doesn’t burn much. And wants to go out. On high the side of the box gets up to 550 (via magnetic flue temp gauge) I turned it down to the guys “medium” setting and it drops to 200* before I turned it back up to prevent from burning out

If it is a "makeshift" rheostat you should get rid of it and get the real thing.Denius wrote: ↑Fri. Nov. 09, 2018 11:28 pm

In your video. If that is really after a continuous 30 minute burn, the fire does not look right. Only the front half of the grate has burning coal on it which would lead me to believe that either the feed rate is too high or there is not enough combustion air.
Does it push lit coal off the grate?
