Brand new and do not have a clue about Harman magnum stoker

PostBy: Chuckie D On: Sun Apr 28, 2013 8:03 pm

Hello My name is Chuck and I am from Au Sable Forks, NY. I recently purchased a Harman magnum stoker and had it installed in my basement. I got it to heat my down stairs and help with the rising fuel costs of my upstairs. When it was installed they put the thermostat about 4 feet from the stove. Im guessing this may be a problem, and may cause a need for me to relocate this? Also is there any setting I should be at for on and off time and blower time? The place I got it from and installed were not very helpful at all and did not know the answers to my questions. So now Im kinda freaking out thinking did I make a mistake? When burning you are supposed to have about one inch of unburned coal before it falls of the grate in to the ash pan correct? This is controlled by the feeder? Also is there anything I have to do when IM done using it for the summer besides emptying out the hopper, vacuuming the ashes out and cleaning out the ash pan, and running a brush through my chimney? Any help would be greatly appreciated. Thanks.... Chuck

thermostate 4' away from the stove is a problem for sure (relocate it to a better place). one inch of ash at the end of the grate is normal (most will say 1.5 inches), cleaning is "key" on these stoves and that means every piece and every inch and often! You did well to get one of these for free or cheap or however you got it... I personally would not buy one because of the price (crazy money at $4k base) and the company (who never wants to talk to you and wont allow dealers to give incentives and wont allow parts distribution and god forbit you need a part you will pay through the nose) ...but their is no denying the fact its a great stove. (I just wish their customer base would force Harmon to release their strangle hold on the world)

The chimney is not all that important other than cleaning out the fly ash that accumulated in the clean out or bottom of the chimney. The only thing I have ever done with a chimney is use a mirror to look up it about once a year to make sure there isn't any issues, nothing wrong with running a brush down it if that is what you want to do. What is important is to take the flue pipes completely off, fly ash will accumulate in them and eventually block them. In addition to the safety issue that fly ash is going to attract moisture which is going to turn your pipes to dust.

Once you get them off and clean out the stove you can use a baking soda and water mixture to wash it down, that will neutralize the acids and help prevent corrosion through the summer. Leave the doors opened so air can flow through it etc.

There is probably more maintenance for that specific stove but I'm not familiar with it.

Welcome Chuckie D!! You did not make a mistake getting that stove. Harmon reps and dealers and installers are not the most forthcoming with information regarding their product. You will be surprised at how much you will save on heating costs if your on oil.

Ditto on the cleaning comment. Brush down the inside of the stove and try and get ash and ash dust out of everywhere you can see. Pull the flue piping( put down some plastic first) and empty it out. Brush each section out and store in a dry place. Coal ash has sulpfer in it. Sulfer plus moisture equals sulfuric acid which can eat up your thinner flue piping over one summer. Some people advocate putting a 40 watt light bulb in the firebox to provide a little heat to keep moisture out. Others like to let it stay open to the air. The key is DRY air or some other means to keep moisture from humidity out.

If you run into issues don't hesitate to ask a question and we love pictures of your setup, your coal storage, and cleaning techniques you employ. Welcome to the world of burning black rocks. :D

Should i still pull apart the flue piping if i just had it installed and burned a fire in it once for two days? Its brand new flue pipe. I have a dehumidifier, should i run that next to the coal stove in the basement to reduce the moisture? Thanks

Yes, I would. Many chimneys have a slight downdraft and humid air from outside will travel down the pipe into the stove. Moisture is the enemy of coal stoves. Buy a 6" cap and insert into the chimney opening. Very nice setup by the way.

Real nice setup! It is a good stove, just no customer service from Harman and the dealer help can be real weak too.

Some other maintenance items....

Another vote here for disconnecting the flue pipe from the chimney. I now stuff the thimble with fiberglass insulation to keep the stink bugs from accumulating in that horizontal section over the summer. I bet i had a few hundred in there last fall! They should now just drop through the open clean out at the bottom of the chimney.

Clean the fans real good, especially the fins on the squirrel cage blowers, a drop or two of oil in the oil port on them too. a drop or two of oil in the stoker motor too. vac out the stoker area, fines tend to accumulate back there.

Clean off the hopper real good and maybe even give it a quick coat of spray paint if it has some bare metal areas - especially the 'lip' where it feeds into the stoker.

I would move the thermostat to wherever you want your control point to be. My 'stat is upstairs while the stove is in the basement.

clean off the ash pans real good, my observation is they tend to corrode more quickly than other areas.

Pick up some rope gasket to have on hand for next year or the year after. Its better to have and not need than need and not have.

Are the fans fairly easy to take apart to clean? IM just nervous for I am not handy at all. I am so irritated that I paid to have the stove professionally installed and they put the thermostat 4 feet away from the stove. To top it off I know nothing about it, and every question I asked when they were installing it I was to refer to the manual. Well I read the manual and I think Im still pretty clueless. I just hope when I get the stove dialed in and a routine how to clean it I will feel much better about my purchase.

Im not sure what brand blower harmon uses (If its like a Fasco its difficult, if its Like a Grainger its easier) but hopefully you wont have to take it apart (most are sealed and unless the design allows the fan to overheat you wont need to get into the sealed area, you can pull a grommet fairly easy to blow it out from time to time), what you do want to do is use a compressor and blow out the squirl cage as much as possible and once per year take the blower of the stove (that should be made easy to do with a few bolts) and then you can blow out it better and blow out the housing as well.

The Harmon used to come with about 12 feet of wire for the Thermostate and a kit to extend that if needed another 25 feet or something like that.... where this 4 foot crap came from i dont know :shock: Call the dealer and ask them to come relocate it for you at no charge if this is a recent purchase.

Im learning these stoker controls myself and found the Coal Troll unit to be very user friendly (but it does take an hour of reading and playing around with it). Dont be afraid of it at all... get right in their and start playing, even if your doing it wrong you will pick it up and understand it better the more you DO IT and it may be easier then only reading the manual.

Its easy to clean off the fins of the fan. Slide them out of the flange holding them on the stove. A couple hex head screws to remove the screening and then I use q-tips soaked in your choice of solvent run the length of the cupped side of the fins on the squirrel cage blower. Takes a little time and patience, but once per year at the end of the season and a drop or two of oil in the oil ports and your fans will last a long time. I am still using one that was on a stove I bought in 1993.

You asked about control timing in your first post. I have mine set at 3 minutes of run time and 11 minutes off for 'idle' mode - this timer control is only turning on the stoker motor. I have both fans running all the time by plugging them directly into a receptacle. I found, like others here, that running the combustion blower all the time gives a more complete burn of the coal. I keep the distribution blower running all the time to wash that heat off the stove and to help keep the airflow constant through the house. Since mine is in the basement it helps my situation. You will need to experiment a little to see what timer setting work best for your install, but I would bet it is only a minute or two adjustment off those numbers.

I think the biggest adjustment to watch closely is how far open the damper plate is on your combustion blower. If it is open too far you may push CO out of your firebox through your hopper. If it is not open enough it will not provide enough air to burn the coal completely and you won't get the most heat out of your stove.

Do you have a couple CO alarms? If not get at least two with digital display like kidde nighthawk. Do you have a manometer on the stove to monitor the draft? That will help set the damper plate on the combustion blower correctly. Search manometer and check the pics of various installs to see what I am talking about. I would hope your installer did that set up for you but I wouldn't bet on it. Don't worry about 'getting' all this info....there is a wealth of experience on this board to help and people are very patient walking you through the process. Someone may be close by you and be willing to stop by to help out in person too. Many on here have done that to help a little more efficiently than plowing through a couple dozen back and forth posts.

Edit to add.....meant to ask if you have a super mag stoker or regular mag stoker. Could you post a pic of your control box? My timer setting comment would not apply to the super mag controls.

I'm with you. I just got a Super Mag Stoker...and have no clue how to use it. It's pretty heavy unit isn't it? I have a MKIII now and will have to take that out and install the Mag. The Mag is just sitting in the cellar next to the MKIII.
From what I have read you can add a extension on the temp probe. Up to 25 ft away. I was hoping I could get it 30ft away due to were I need it up stairs. Don't know how the extra 5 ft would affect the function.
My biggest concern is in the early fall or spring how to idle down as low as it will go with out going out. ..
