A disadvantage of having a coal fireplace insert rather than a stove is that you don't have access to three sides of the beast. How are fireplace inserts shaken? I am particularly interested in the Hitzer and Harman coal inserts.

You can reach the shaker handle from the font on the Harman

This link is broken, either the page no longer exists or there is some other issue like a typo.

I would image the Hitzer is similar.

Welcome dstienel,
I have a Harman insert and have to say that I don't shake the ashes, I shimmy or vibrate the shaker handle that comes off the left side of the stove. If you do it right you never loose any large pieces of red hot coal, just some very small embers that let you know it's time to stop. Hope this helps.
Again welcome to the forum.

Isn't that shaking down? (Define shimmy & shake....without the music please!) :P

Wow Ashcat if I were to shake my Harman down that hard the grates would be stuck and I would have to do a total dump. Harman's take a more subtle approach to a shake down, and I do a few things different.

!!!CAUTION DO NOT LEAVE A COAL STOVE WHEN LOADING COAL OR UNLOADING ASH!!!
this can cause an over fire in the stove and the stove can become extremely hot
possibly causing a fire.

1st. open the ash door and remove the ash tray with the previous shake down ash, I do it this way because it's at the coolest temperature at this point I have found and if anything does happen at least in my mind I like it as cool as possible.

2nd. Open ash door for a few Min's and let the stove get a bit hotter in temp (throttle it up a bit), normally 15 Min's is more than enough time for this.

3rd. Close ash door and close damper control on ash door. I do this to keep the fly ash (dust) down, keeps the dust in the stove and out of the house.

4th. Do the Harman shimmy, vibration, light shake down, until you open the ash door and see a bit of red on the ash pan. Open the ash door only slightly or the fly ash (dust) you don't want will be in the living area.

5th. After shaking and seeing red embers on the ash tray, close the ash door and open the ash door air damper all the way for another 15 Min's or so to get the temp back up (throttle it back up), this will also clear away any fly ash in the stove.

6th. Now that you have brought the temperature of the stove up higher than normal it's time to start putting more coal in, I do this in three steps.
A. I take and split the grate area into 3rds, the left and right thirds I put a layer the thickness of the coal in leaving the middle so it can burn the volatiles off. Open the ash door and let the stove heat back up and ignite the fresh coal, about 10 or 15 Min's.
B.Close the ash door and fill the center section, I close the ash door just to keep the dust down, Open the ash door back up and let it ignite the coal. This method helps to prevent the volatiles from collecting and exploding causing puff backs that we all seem to have at one point or another.
C. continue this procedure until you have filled (banked from front to rear to the top of the fire brick) your coal in the grate area. Normally after the first layer you will find that you can fill the whole grate area at one time since the very front will be filled and have nice red coals to ignite the volatiles of the next layer or layers of coal.

7th. Now that you have the grate loaded with coal and it is ignited it's time to close the ash door and set the ash door air damper to the desired setting you had before.

8th. Use your ash vacuum to clean the area up, guys you have to keep the spouse happy or else!

Interesting Jeromemsn, how we all evolve methods that work for us. Why would your Harman grates get stuck? Why can't you fill 90% of your coal bed all at once? If the Hitzer ashpan weren't as shallow as it is, I'd probably wait until the ashes cool, too, before emptying them. But with a big load of ash, the ash in the pan is very close to the underside of the grates, and I would be concerned that I wouldn't be getting enough fresh air to the grates, especially when I'm trying to get new coal lit.

I think one HUGE variable, in how each of us works with our stoves, is the amount of draft. Mine borders on being too much, but one advantage of this is the vacuum effect to suck fly ash up and out the chimney. I see this most clearly when I put the empty ashpan back into the stove. The movement of dropping the pan (even 1/2 inch) after I've inserted it all the way causes a little puff ash, but this is immediately sucked back into the stove. I have no need to use a vacuum cleaner, except the hearth getss small amount of ash and coal dust on it, which I wipe up with a damp paper towel.

The big draft also means that livening the fire, and igniting new coal, is a pretty quick process. I have also, a few times when I've forgotten that I left the ashpan door open, heard a bass note--like the bass note of a pipe organ, but a little less pure in tone--start to build in the house :o I rushed in and half-expected to see the cats clawing the carpet to keep from being drawn up the chimney :)

Ashcat,

that video was well done and very helpful.Thank you.

How do you vent your 983 up the chimney? It seems to have an 8 in diameter round hole at the top which serves as an exit for exhaust gaeses. That round exit hole at the topseems to not have a flange in the pics I have of a 983. . Did you mate that exit opening to a 8 in pipe and run it up the chimney, or something else? Are you happy that your chimney provides about the right amount of draft to run your 983 in the ranges you like?

I had it installed by the dealer. Unfortunately everything happened so quickly I'm not certain of answers to your questions. I am happy with the chimney, and I can control the stove how I like it but, because of the strong draft, tiny alterations in the air vent hole size produce big changes in stove temp. When I'm cruising (after new coal is lit and I'm setting the temp for the day) my air vents are never more than 15% open.
