Harmon Ash Pan Size

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.

Mine has exterior dimensions of:

15 & 15/16" wide
15 & 5/16" deep (plus a 3/4" top lip that folded handle rests on)
7 & 5/8" high

If you make a box without the top "front" lip I'd just make it 15 & 7/8" deep

You will want the lip if the set up is like the older mag stokers. Without it there is nothing to grip as you lift it to pull it out of the ash pan area. The first one Freddy made for me I told him not to bother with the lip but I struggled to get it out when it had the weight of the ash in it. He sent down a small angled piece I bolted on and it works fine now.

I made one for my Harman Mag years ago, the original one rusted out. When I made the replacement I included the angle, as you said it's the only way to lift it up and then out. I also coated the metal with RUST-OLEUM Rust Reformer,Black,15 oz. - Paint Primer, Sealers & Rust Reformers - 5HE25|215634 - Grainger Industrial, 18 years and the ash pan still looks like new. Thanks for the information.

I had Freddy leave the lip off when he made my new ash pan. He put a front handle on it instead and that works fine for removing the ash pan from the stove. I'm glad to have the additional space for ash. The lid he made fits both ash pans but the folding handle on the original allows ash to escape into the room under the lid. I prefer the one Freddy made hands down. Lisa

Yep - Freddy is the ASH PAN MAN ! :D :notworthy:

neither inclined nor determined to commit crimes. ...Such laws make things worse
for the assaulted and better for the assailants, they serve rather to
encourage than to prevent homicides, for an unarmed man may be attacked with
greater confidence than an armed man."

photos of this design please when you have a chance.... TY (wonder why Harman could not have made a simple, better improvement like this?)

Pictures of my ashpan. The handle on the pan allows me to easily remove the ashpan. Since I have two ash pans I never have to carry a hot one outside. I remove the pan from the stove, put the lid on and sit it to the back of the hearth until it cools. Freddy also made me two ashpans and lid of the same style for my Mark I. They work great, too.

great pics lowfog! nice work on that ashpan from fred (heavy gauge, tight seams)... I bet money you could increase the height of the pan by at least 1/2" without effecting performance at all (If he does a second one for the Harman have him try it). Even if your carrying a hot ashpan id still prefer Fred's style over that stupid swinging unbalanced mistake (you need to grab the upper lip, does that swing handle hit the door opening?) I guess because im a guy its easier for me just to one hand it on Fred's style with a pot holder right out the door (maybe for large, deep stoker/furnace/boiler pans that swing up type handle might be justified?

can we ask how much Fred charges for a custom ash pan?

Believe me between DK, an engineer and Freddy, we tried to increase the volume of the ashpan. There is no way to do so because of the lip the Harmans have on the ash compartment. The ash pan doesn't slide out, you have to lift it over the 1.5 or 2 inch lip. It's a tight fit especially when the ash pan is really full after a longer burn.

That lip is a pain in the butt. It reduces the height of the ashpan by a couple of inches. Additionally, since the ash pan doesn't quite fit width wise, a lot of ash misses the pan and has to be dug out frequently. As you know anytime you have to mess with the ash outside the stove, you are going to release ash into the room; even a little released ash is too much. I consider that ash as my nemesis. :)

The swinging handle actually folds down to become the top 1/2 inch of one side of the pan. That's why it leaks with the lid on. I always wear my welders gloves when dealing with the stove or hot ashpan. As I said, I remove the hot pan, put the lid on and let it cool before I take it outside the next day.

That way the pan is cool and I can carry it with out gloves. Being able to deal with a cool ash pan is also a safety thing. I worry about dropping the ashpan inside and leaving an unnoticed hot coal on my wood floor. Sadly, I did drop the ashpan a few days ago when I tripped over the cord to the stove's fan. I'm thankful that I was dealing with a cold ashpan.

I can't say how much Freddy charges for an ashpan and lid. I'm a capitalist and the market, i.e. Freddy, sets the price. I do know I got a great deal and a much better product than what Harman supplies with their new units. Lisa

AMEN to that!! The one he made for my Mark3 was as tall as possible, I think I had 1/16th clearance as it was tilted to get it in there. And how they designed the grates wider than the pan can be makes me think of those idiotic auto engineers that make you remove a tire to get to an oil filter or change a headlight bulb.

AMEN to this too! He has made a couple for me and they are heavier gauge than oem and show no signs of rusting or flaking like the oem's after a few years of use. I'll also let Freddy set his prices. I hope he is still making them when I need a replacement for the oem pan in the shop.

I like Harman's design on the Super Mag. It has the folding handle. I use it all the time. What I do is simple . I grab the pan lip with my finger tips. Slide the pan out some then open the handle as I'm pulling the pan out then carry it out the door to my steel barrel which serves also for driveway sanding. I have heavy gloves that insulate the heat when running full heat and keep my hands from getting dirty. I would not like it with out a lifting handle.
My grass has never been better using ash for sanding instead of the old sand/salt mix. I drive on part of my lawn often so the ash is much better. Also The ash doesn't freeze up like sand/salt combo that I used. Also the main thing is when it rains and the ash runs off it helps fertilize the grass.
Can't complain about that design on my end.
