DS 1500 - A couple things I learned about shaking

PostBy: MarkV On: Wed Feb 06, 2013 1:22 am

I've continued to use my "rberg poker" (made from the old paint roller handle) to loosen the ash buildup at rear of my DS 1500's firebox. Seemed to be helping--I'm getting more ashes in that area of the pan.

I've also been shaking the grates according to the manual and what posters on here have said: shake until hot embers are dropping in the ashpan and there's a healthy glow visible over the ashes. But I was getting more than embers--I was getting sizable hot coals falling into the ashpan here and there.

Finally dawned on me last night that I've been moving the shaker handle a bit too far to the front and back when shaking--opening up too much space between the grates and allowing larger hot coals to drop. Today I tried using a much shorter arc on the shaker handle, and a-ha...the desired effect: small hot embers instead of the larger coals, dropping here and there over most of the firebox, and the glow of the fire visible over most of the ashes. I'd estimate I"m moving the grate handle only about 1" to 1.5" total, where before I was moving it back and forth in a 3-4" range.

For the ash buildup in the back, I tried the opposite trick before I shook the ashes. Right before shaking, when there's a good layer of ash between the grates and the fire, I moved the shaker handle slowly about 4"-5" toward the back, just once, then back to center. Then I moved the handle slowly about 4" toward the front, again just once, and back to center. This slow pivoting of the grates up into the ash layer appeared to break it up somewhat. After this, I did the rapid, short-throw shake to drop the ashes.

After shaking and letting the fire heat up a few minutes with ash door open, there was good amount of hot coals and blues at the back of the firebox--maybe the best yet.

Once you figure out how the STOVE wants to be tended, and not how YOU want to tend the stove, you'll have it made in the shade.

MarkV- I agree with you, I get the same thing with my DS, its harder to get red at front and back of grate. Comparing my new DS to my old coal stove, the grate (teeth) are much smaller.

Oliver,
That is the best synopsis I have ever read about tending to a coal stove. :D :up:

I've tried smaller arcs on shaking too, but it seemed after a few days I would get ash build up in the coal bed to the point that the fire wasn't burning as good as it used to. I've decided that loosing a few hot coals to the ash pan - maybe a pound or two of smaller coals that are mostly burnt - is well worth the trade off for a good healthy shake down with a better clearance of ash. Mine is designed different than yours, maybe you will have different results. 8-)

I also use a slicing and poking tool to go up thru the bottom of the grates to insure good combustion air flow into the coal bed.

I just tried to shake my 1600 down the way you described. It didn't like it. Grates were immediately jammed and I had to crush the clinkers before they'd move again. My front and rear grates are still out too. Well, I wouldn't say they are out they are just covered in ash. They still burn.

DITO on my DS1600 as well! Works best for me with fast - short strokes (lol) :P

Update...I've continued to shake with the method in the OP. I've also continued to poke the bed from underneath the grates.

I mentioned there was a pretty good ash buildup in the back of the firebox. Well, last night, I noticed that poking through the ash at the very back row of holes was much easier than before...not nearly as much resistance from packed ash as before. Looking in through the ash door, I could see a dull glow through the holes I'd poked...I haven't seen that before when poking at the back.

Not sure if it's the slow, full grate movement I described in OP, or the poking, or a combination of both...but it seems the ash buildup is being reduced.

FWIW... :D
