I have had an Amaizablaze 4100 for seven years. I burned 100% corn until this year. I bought the Multi Fuel conversion kit in fall 2011 and have been burning Henry County hardwood pellets. The glass door of the stove gets completely covered with soot within a half hour of starting the stove after cleaning. You can't even see the flames after about two hours. When burning corn the door would never get covered up like that. During the weekly shutdown for cleaning I find the inside of the stove has a lot more ash and soot than there ever was burning corn. When I installed the conversion kit I set the combustion air screw for 2 1/2 turn CCW. I have since backed it out further but it does no good. The stove is used as a fireplace insert and is vented through 4" pipe up about 20" of chimney. I heard wood pellets were supposed to burn clean but so far that hasn't been the case for me.

If anyone has an idea on how to fix this I would appreciate hearing it.

exhaust pipe obstruction ? I have the external mounted fan and mine plugged up the safety grate on the exhaust fan. It was gummy almost like a creosote buildup.

Sorry to hear of your problem Cornstarch, You are not moving air through unit which means all this bad stuff will happen no matter what you burn. First did you remove the positive draft motor and place hardware cloth over hole? Probably not since there is nothing in instrutions about that. I am wondering if the inlet of positive draft fan is plugged if you didn't remove it. the opening isn't that big. You either have air exit problem like cowtrimmer says or you can't suck air in. If you want to check where you are on air adjustment you can see air valve from front with pot removed. the gap on mine is 7/32nds and is burning 625 on front and room air is 335 with your setup. Something is abstructing your air or the exaust fan isn't working. I am not clear where the fresh air comes from and your chimmny setup could you give detail on that?
This is my window after several hours.

Cornstarch, When you made the conversion did you put the 1.25 (approximate)inch plug in cleanout/vent?

Do yourself a favor and go back to burning corn.

I too have burned corn for several years with my Amaizablaze 2100.

It only took me 20 bags of wood pellets to realize corn was much better in many ways.

I had a messy stove, jammed auger many times, and less heat.

I am glad I tried pellets though, so now I know for myself not to do it again.

did you add a piece to your fire box in the back by the pipes?

Yes I did tailboardteck,What is in picture is tin fashioned as you see, I now use stainless which is durable and long lasting. It has increased room air temp 10 degrees but lowered stack by about 20 degrees.

Run that exhaust pipe info by again. 20" or 20'?? Vertical exhaust pipes will plug at the bottom with ash and soot. They require regular cleaning. As soon as the exhaust starts getting restricted the door glass will get coated with ash and soot and the fire gets really crazy looking. Been there-done that.

cool tfgrower i love playing around with these stoves there so simple i cant really screw them up (ok, i have but i put it back together again)i might just try that on mine i think i might even have some stainless laying out back from a tuck body i fixed.

It does force the heat up through the pipes better. To simplify attachment buy a sheet metal clip 14 inch and eliminate screws. The clips or what ever they are called fasten cold air ducts togather. If Tinman is around he would know what they're called. Cut the stainless flat and bend aboout 120 degrees. Total width before cutting is about 3.5 inches. Good luck
