In all the years I've been associated with AHS, this represents a gross mischaracterization of our record. We have many hundreds of satisfied customers. In the spirit of NEPACrossroads, I suspect that freetown fred very much dislikes it when foreign countries criticize the U.S. regarding its conduct of its own affairs. My attitude is similar, regarding his criticism, given that he does not own one of our boilers!

Well, being you had to jump from PM's to public--I'll respond as I already have to you PM wise--my 2 neighbors that did spend the exorbanent amount of money for your boiler set up & have had constant problems with puff backs, why would I even consider owning one--both these people have contacted the company--back when--to no avail & pretty much got a bunch of defensive answers instead of any specific fix's--I think the biggest one was--all settings are not the same & there is no solid fix all--sounds to me like you have read the same rule book--orrrr, with your defensiveness here, might even of written it--I ask again, are you currently affiliated with AHS??????????????? You stated in one of your PM's that you FELT they are on the right track???????????????????

Your neighbors are welcome to contact us.

The Wood Gun is a property of AHS, and my email address and my listing as an AHS rep, plus the contact info ought to clue you in as to whether or not I have a role with the company. You were the first to jump from our exchange of PMs to a fresh, public post. I am done responding to you and will ignore further posts. I wish you nothing but the best, and hope for your release from whatever bitterness drives you to take this up as a cause when you do not have a personal stake.

Anybody designated as "<insert manufacturer> Rep." is absolutely affiliated with that company. That is something that is verified by me, you can't just waltz in here and ask for it.

Let's get back on topic here. You've voiced your opinion Fred so let's leave it at that.

I am not an AHS customer, but I think you need to consider the possibility that motives other than "bitterness" are at work here. Of all of the 7400+ registered members of the forum, freetown fred has made the most posts of anybody - even more than the Mayor. While I don't know him personally, and haven't read all of his posts, the many that I have read come across as supportive of people of all coal-burning persuasions. Looking back over this thread, there have been many posts by non-AHS customers asking questions and offering suggestions to try to help the members who do have the type of "personal stake" you reference. Many of them have lengthy experience operating different types of coal-burning equipment, and may have useful insights to offer. My point is that many members here give of their time and effort to be helpful and supportive to other members, and their input should not be dismissed or their motives impugned on the basis of the equipment they operate.

Folks, I feel like I've kicked a fraternity member in the shins, then stood around to see what would happen next. I mean no disrespect to anyone, but feel like I'm taking it on the chin for pent up frustration that while it may be real enough exists in a kind of virtual space. Between posts from 2 years ago and the folks calling in with questions, you know where my priorities lie. That said, I don't care how much bad blood settled in the last 4 years during which I've not been involved, I'm willing to work with folks to make them satisfied. Give us time. Give us the benefit of the doubt. Kinda wish Patrick were here to take some of the heat. :(

I don't own a boiler. I haven't ever seen one of this type, but why doesn't someone do a simple experiment: Introduce an appropriately small constant flow of air into the chamber (location) where the explosion occurs. In hours or days, one could see if it eliminated the problem.

@ Mike: I have no doubt that you and the company have tried to come up with a simple fix suitable for everyone. That, unfortunately, has proven impossible. Please don't take all the negative comments personally. I have and do enjoy ALL sides of an "argument" for lack of a more accurate term. You are the visible target and you remain visible here on the forum. Thank you! I have no idea what the "problem" is with the coal gun or how to fix it. I wish I did. All we all seem to be asking is don't give up and keep trying to find a solution for those who need one.

Best regards,

Peter

Like maybe the manufacturer? It seems it would be pretty easy to set up the environment to cause a puffback and then do what you suggest to see if it would eliminate the issue. Maybe they already did this and this is the info they are doling out to the customers that are calling asking for suggestions.

I have two friends running older 130's right now and they have for many years. (One is an original Eshland from Ben Witmers Hardware store). I have a pair of 260's also along with the AA 130's and 260's so I see both sides, and still support the efforts by each company to keep folks safe and content. We have not had any puff-backs on any unit. No, I don't use 'miracle coal' or have any NASA equipment on them. Secondary air at the observation door is essential. If you adjust the door to be tight, you are not paying attention, it needs to hang loose and provide air over the fire to quickly remove the volatile gases. AA has a 1/2 hole with a removable chrome cap......like the situation at Keystoker when they added a small motor to provide air to keep the fire burning at an acceptable level. Most of you know a Hand-Fed stove will blow the door back HARD if you get too much fresh coal dumped upon the sleepy fire. Same is true for AHS and AA. I know they tell you to start up a new or empty boiler with a 5 gal can of ash. Well, when you are 150 miles from home or just plain forgot, I have started a hundred or more pots with ALL fresh coal, and there is no issue. I use a LARGE propane plumbers torch, and there is nothing lazy about the heating and igniting of the coal. 5 minutes and we are at full fire. I do, however remove the twisted belt on AA's to stop the auger and ashing, and on AHS models, I disable, temporarily the ashing motor circuit. The most critical part of the puff back is lots of fresh coal and lots of ashing that removes the ash bed and provides too much air to a fresh fire. Once again, I will say to everyone, change only one parameter at a time AND record the change. DO NOT play with the damned fire. Unlike wood, coal HATES for idiots to keep opening doors, access ports and feed rates all the time. I have done this for a long time and the biggest enemy of the boiler or radiant unit, or hand fed is the idiot who won't/can't relax and let the process function. If you think you are smarter than the guys who envisioned, built and support these fine products, then step right up to the Bar, and spew your knowledge. .........and Larry, NO PM's; no questions, no posts.....just f****ing relax and burn as you learn. I don't want to offend anyone, but PLEASE be proactive, because if you are not part of the solution, then you are damned well part of the problem!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :idea: :idea: :idea: :idea: :idea:
Why do I have dozens of these things running and have no Baro's rocketing into space? Supple air, exhaust piping, chimney construction, height of the fire in the chamber....... 'habits' of the homeowner. Start here, and we will be able to make this long post a non-issue. PS Freetown Fred meant no disrespect, he is merely trying to help out the good folks who read the forum. Some folks 'rub' you' the wrong way, but he is a Vietnam Era Marine Medic, and I can tell you, he is used to making decision that impact peoples lives, and he would walk to hell and back....well, at least to Cortland...to help anyone out. "Hell' would be down below Yanche in the District of Columbia, and that long wall has too many friend's names on it for him.........and me, too!

Whistlenut, this may seem funny perhaps, but right along with you I'm the one most typically supporting AHS here on the forum, and the group often reads my posts saying that I'm happy and quite satisfied with my boiler. What is your personal problem with my support of AHS if I might politely ask? How exactly does this make me part of the problem?

This is approximately where I try to keep the fire height. Notice the bottom of the feed tube
[nepathumb]45802[/nepathumb]
Here's the pics of my flapper and fire height I was asked to send. One thing I would like to comment on is what is causing the bangs. Most people I assume blame coal gas as the cause. I haven't read all the posts from page one so I don't know if someone has this theory. When I had severe bangs the resulting smoke & smell was exactly like setting off a black powder cannon. I feel the bangs are caused by the fines of coal dust from the hopper. This is why if the fire is kept close the feed tube the fines are simply burned away. If too much unburned coal is on top, the unburned fines can be drawn off when the fan coast down and ignited by the volatile gasses that are burning then get that big bang that blows things apart with that gunpowder smoke&smell. The lower the fire the more fines. In an earlier post I said I smelled sulfur before the bang occurred. Once I started to keep the fire very high, no smell, no bangs. Fine carbon dust plus sulfur is gunpowder. Some boilers have means to separate the coal from the fines but the coalgun is not one of them so I had to work around it by getting the fire as close to the feed tube as possible. As long as you keep it from burning up the tube by careful adj. of the timer it has worked for me. Without the bangs I absolutely love this boiler. This is my experience with the ahs 130 since 2008 and for the last 2 years I've bang free.
