I was just wondering if anyone has installed a draft inducer fan on their Econoburn boiler? If so did it remedy the 'back puffing' and reduce smoke when loading?

After reading your most recent post, it has me wondering if the backpuffing that you described is a separate and different issue than the mini-explosions that some of us have experienced. I've never had anything along the lines of the backpuffing that you described, but for a couple of years did get a few, very infrequent mini-explosion. These were always isolated, singleton events. One of the characteristics of the mini-explosion is the fly ash being blasted out of every unsealed place on the flue piping. There is obviously quite a bit of force required to do this. Since the damper door doesn't get blown open (at least not in my case), the only other path of the explosive power is via the HX tubes. And the only connection from the upper to lower chamber is the gassification nozzle. Because of this, I didn't think the mini-explosions originated in the upper chamber. Could that much force be transmitted from the upper to lower chamber through the relatively small nozzle, flood and compress the lower chamber, and pass up the tubes that quickly and powerfully? Normally the non-gassified, combustible gas travels from the lower chamber up the tubes, unless something holds up the flow, such as a partial blockage, or perhaps a period of downdraft from inversion. I had been thinking that the lower chamber was getting filled with combustible gas during momentary periods of non-gassification. Then, when the torch is lit ... kaboom (sort of like an engine without the compression). It's fairly easy to imagine an explosion in the lower chamber driving everything right up the 4 tubes and into the flue. Do you think what I've described above is possible - i.e. your backpuffing being separate and distinct from the some of the other mini-explosions?
