Hyfire II Hot Coals Falling Off One Grate but Not the Other

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

Hi, hope you all have been nice and warm this winter, we have!

Just a little issue with our Coaltrol/Hyfire II. This is our first winter with coal and this stove, so we're still working out the details. The Coaltrol is set at MIN 4 and MAX 36 (down from the factory setting of 38).

When the left burner ONLY is lit, there is NO hot coal falling off the end of the grate into the ash pan. When BOTH burners are lit, there is still NO hot coal falling off either of the grates. However, when ONLY the right burner is lit, we've got hot coals falling off the end of the grate into the ash pan. Is there some adjustment that needs to be made? Why is this occurring with only one grate, and ONLY when that one grate is operating by itself, and NOT when both sides are lit?

Thanks!
Connie

i don't know much about these units at all but my first thought was is there is combustion blowers for each side is it possible the blades for one are backwards? not enough air for complete combustion or a gasket issue thus the bypassing of combustion air?

If this issue just started as of late, I would check your line voltage, especially since the last storm and being in Eastburg

Probably slight differences in the Stoker Motor Speeds, bearing size, hole in the stoker plate, etc..
Back your MAX down 1 more point and see what happens. Sometimes if you get a large chunk of coal, rock, or a clinker, the whole thing will move down the plate and fall off.

As has already been suggested the mechanisms are slightly different due to manufacturing tolerances and differences in fan output and stoker motor RPM. Having said that the reason that there could be coals falling off one side and not the other when they are burned individually is that the over fire pressure changes with one Vs two burners.

Simple answer is just back off the max one or two and the problem should be solved. :)

Hi guys, thanks for the help. I'll drop MAX down to 35 and see what happens.

You may want to take a look at the stoker adjusting bolt and bar to make sure no one has turned it in too far. When I went over mine this fall (bought it used ) I found that on of the bars the stoker arm/roller runs against was bent a little from being adjusted too far. If this happens I'm pretty sure it would the change the amount the plate moves and cause an issue like this.

The Coal-Trol equiped stoves come with a non adjustable carpet, although your suggestion is spot on for those who retrofitted their stove to add a Coal-Trol to the adjustable feeder style. In that case we reccomend that you trun the adjuster all the way in and lock it down so that you will not have issues with it changing. For this configuration your min and max will be different from the factory default for sure. :D

One other note, on the non-adjustable feeer carpet it can be bent in the back by a rock or other foreign object in the coal. So if anyone has a dual feeder that has been running for a while and it starts to feed unevenly, remove the carpet and make sure the back is straight across. You can simply bend it back with a hammer (gently! :lol: ).

We've dropped MAX down to 32. We noticed that we are still getting burning coals dropping into the ash pan when using only that right side burner. Doesn't seem to be anything stuck, everything seems to be in order. Do we drop MAX down even further?

Yes, you could drop it 1-2 points, (31, 30). Otherwise, you are wasting fuel. If it's only a little bit, probably not a problem. Mine gets real close and maybe loose a few, but it is pretty stable at full feed rate (FR=99). it's get blazing hot though! 550+ Degrees! but it usually doesn't stay there long, the temp gets satisfied pretty fast and it starts backing down.

Well, I'll try it if we ever get colder weather again. With the temps where they've been, I think we should shut down and test it out next season. Thanks, Dave.
