I was thinking that if your stoker is feeding fast and heating too hot...that maybe the sensor is not functioning properly...just something to think about

+1 for the Handfired Crew @ Nepa

Handfired is sounding better all the time. I spent a pile of money on this stove for it to run so poorly. Now I have just spent another $120 on new grates. Not to mention all the unburnt coal that poured over into the ash pan last year.
It will be someone elses problem if things don't improve this winter. I am going to try the Coal-trol this winter. I don't think the problem is with the mechanics of the stove. I think the electronic controls for the stoker is unstable......

Because I don't like seeing manly men patting each other on the back in a girlie man forum, I'd like to call it -1 for the What Were They Thinking Crew @ Harman. The original Harman Mag was a reliable, heavy-duty unit that set a high standard of performance for stoker stoves.

It does seem like there are too many examples of good stoker products getting "improved" by plastic parts, other cheap materials and electronics that don't work reliably in the harsh environment of a coal appliance.

I have been using the Supermag now for 5 years and yes the grates are supposed to be re cemented in after you remove them for cleaning. You also have to keep the feed rate set at about 1.5 so you get the 1 inch of ash at the end of the grates. I use stove cement from tractor supply and it works perfectly. A new set of grates should only cost you 80.00 at your dealer. I burnt up and warped my first set of grates because I never cemented them back in and had the feed rate to high and was wasting a ton of coal the first season.

You must be thinking about Harmons old prices Harman Mag Stoker Grates ... they are now thieving bastards (yet people still give them money hand over fist )

I could pull up 100 threads talking about the failure and expense of running these things... but im glad to see some (like yourself) got lucky. I would not assume for a second that new Harman buyers would be so lucky as you

the poster had it correct at approx. $120 for a set (the same was $60 several years ago). Mind you.... this is only one small example of the price increases and the "forced" demands placed on Harman dealerships across the country! "ohhhhh nooo, we cannot allow Dealers to act as independent agents to give incentives or sales or discounts if they need to feed their families or control their inventory... we need to place a strangle hold on the world because we own the largest market share in the world of this industry".

Its the dealer that is ripping you off I have seen these grates as cheap as 18.00 to 20.00 each. The link below has them for 36.00 each.

I purchased my super mag for 2800.00 installed but I see a lot of people on here saying they paid 4200.00 +.

@ mlchelp ... I know your a good guy so please don't take this personally, you might even be one of the few coal burners from MA.?

Anyways... you are advocating for 2 of the largest thieving scumbag operations on the planet (you have now linked woodmans too). These are NOT Harman grates which is why they can sell them for $40 each plus shipping and handling to make the total near $100 anyways! This tells you HOW SEVERE Harman is ripping its customer base (when another KNOWN thieving bastard can sell a "knock off" cheaper than the manufacturer whos still in business and has these made by the MILLIONS!!!!!) If I was to venture a guess... Harman pays about $4.00 per grate (no, that's not a joke!!!)... Woodmans pays about $12.00 per grate .... are you starting to get the picture yet???

im not advocating for anyone, i'm simply stating that I purchased a set of these grates for 80.00 from my dealer in Blakslee, PA including tax. Others are saying it cost them 120.00 for the set. I also purchased my super mag for 2800.00 installed while others are saying it cost them 4200 +. The high prices are coming from the dealers, not Harmon. I just don't understand why their is so much Harman bashing on these forums. I purchased my stove when it first came out in 2008 and it has been running perfectly ever since. The only issue I had was when I removed the grates to clean under them and did not cement them back in as they were from the factory. I was also new to burning coal at the time and thought that the more burning coal I could get on the grates the better. I called Harman and they were very helpful and told me to cement the grates in and adjust the feed rate so that I have 1 inch of ash on the grate at full burn. Since then I have had no more issues.

I think the high cost's associated with Harman are coming from the local dealers. If my dealer would have told me that the super mag was going to cost me 4200.00 I would have just got a boiler instead. True, I live in a area with several different dealers to choose from so there is a lot of competition in the area and therefore more competitive prices. I did have a few dealers around the area try to get me to pay 3600.00 for the same stove I purchased for 2800.00.

As well, I don't know either, but it would be foolish from a liability standpoint to have a controlling componet that apon it failing...would allow a stove to "Run Away" out of control. One would think it would fail to a Safe state as to render inoperable.

Does not these Super Mag's have a "Blinking Lights" diagnostics code system?

I too get alittle tired of the constant Harman (NOT HARMON) bashing. I just bought a new set of grates from Harman. They were $85.00. My first set lasted 10 years and really could still be used. I don't think that's a bad price for something so integral to the performance of the system. Everything else on my boiler is original.

Not to get pissy but you are on here as a manufactuers rep for a company that doesn't even exist. So I've got to ask. If Crane stoves were so wonderful, why did the company fail? Not looking to start anything here but you are pretty bellicose about anything Harman so you've kinda set yourself up for it.

I get tired as well of those bashing Harman and the rambleing and I'm glad others are complaining about it. My Super Mag was $2900.00. And the changes from Mag to Super Mag seems to suit me.
Some retard didn't set the OP's stove set up right and blew it out then off'd it to the OP. I bet for a few dollars and some effort the OP will have a awesome stove and saved lot's of money besides.
To the OP. Why spend the $$ for a Coal Trol... the probe that comes with the Super Mag works perfectly. I extended the wire 35 ft more up to my living area upstairs. I've had my SM on now for over a month and the living area has kept within a degree. That's the truth. Lows have been down to 12 deg and highs up into the low 60's this month. It idles down so nice. I have my feed set to 2 and the room temp at 70 deg and fan at just above Low. The stove senses what the demand is and adjust's the fan,feed,etc. to keep it.
My coal dealer and some of his clients have the SMag's and have never had anything go wrong with them in 6 years of NH winters...They work hard up here. Much harsher then PA or NJ etc.

Kids ! Kids ! Fighting about Faux Harman's again ? And I'm seeing the same Playground Offenders involved again ! I'll be sending all of your names to the Chinese Consulate(Faux Harman's True Headquarters) so that you can be sent to the Re-Education Camp on this very subject ! :bag:
