I am only getting fines in the tray. Noticed some corrosion on the main feeder body right in front of where the pusher block slides. Could this be a problem? But why will it feed great for several days and then stop if that was the problem? And as I said, the pusher block keeps sliding but no coal is moving so I do not think it is the controller. I think it is a mechanical issue but won't rule anything out. Would it be wise to use some high heat JB Weld and putty knife over the corroded spots? One spot looks to be like 1/4" deep and the size of a quarter. Thanks for the suggestions......I need to go clean all the dust out of the top part of the stove. Quite a build up in there. I don't have a long brush....any suggestions how to get that all out of there?


There's your problem...it should be an Oval...not an Egg...egged means that the motor has over stretched the steel loop, most likly due to pusher jamming on wet fines and corrosion and all that other evil stuff...solve all that and you will be good as new...this happening sure is hard on that feed motor.

You want to be scared...that motor is like in the $350.00 range. :cry:

If it ever becomes carried in our area,Ray,I'll want to give that a spin! One problem that still strikes me is that if it's wet,it's going to really aid the Corrosion Monster on everything it constantly contacts until the heat of the unit evaporates it. Dry is nice,and makes for less Corrosion chasing at the end of the Season. Wolfe,if you can get your hands on that entire unit,I'd be breaking it down and hauling it home. Do the refurb on it and put it into service.

As we note on the Liesure Line Forum, using a couple of plastic bins to air dry wet rice coal for 1-2 days before using is a easy way to reduce the wetness that Ol' Bob notes. Back to the LL forum :} !

Once again,"The Squirrel" tells no lies! There are many ways to accomplish dry rice without getting Exotic or going broke. Sit down,and design it out. The best is dry primary storage without rehandling it multiple times before it hits the stove hopper.

Sure was dirty! Gotta get me one of those dishwasher brushes.......used a coat hanger that I untwisted to get up the sides of the stove on the inside. I lit it last night and filled the hopper with "DRY" coal. It sure is burning nice once again. May consider buckwheat. Does it dry faster or isn't putting damp buckwheat coal in the hopper as much of a concern and if so......why? Just wanted to thank you guys for the help in getting it figured out. Glad to have her burning good again and feeding properly.

This stove not designed to burn buck. Fire will creep back intot he hopper and you will have a hopper fire. Rice only.

its right in the manual ........ page 21 ..... been burning it for the last 3 to 4 years and to me it burns so much better so much less fines

Wrong Size Coal -- The Verti-Flow System is designed to burn rice coal (or buckwheat coal if rice is not available) If buckwheat coal is burned, raise the draft setting from .04 to .06. Larger coal will not feed or burn properly.

i find that its much cleaner and being a little larger it drys faster. the reason i started burning it is because i have the house stoker needs buckwheat and did not want to have to buy 2 different size coal,

i do know there new and improved stoker can not burn buck IRC the super mag


i must of put 10 ton of buck in to this stove as of now and no problems

my box settings are

I know it used to be in the manual. Not anymore. You must have a chimney with excellant draft.

that manual is dated 4-02-09, and they stopped making the magnum a couple of years ago, might have been in 09 or 2010, so it would not be in the manual anymore, the super mag for what i was told can't handle the buck like the older stoves did

and to me rice is harder to burn than buck would be
