I have an e1450 and if I don't clean out the tubes once every two weeks they will get clogged up where the tool won't fit down the tubes. I use a small piece of wire like a coat hanger and run it up for the bottom and down from the top to break it up. I then pull the scraper tool with chains on both ends down through the tubes. One thing a learned is that if you remove the weak chain that came with it and put a heavier duty chain on the tool it will pull down easier.  Glad you were able to clean out the tubes and it's important to keep them clean. I use a shop vac during clean out to remove all ash and debris off the top of those tubes as well.

Hey, PapaTango
Good to hear, but I suspect this is one of those issues that's very fuelwood and dryness-specific.  As for their tool, I gave up in disgust.  It jams randomly, and yeah, the chain is a piece of junk.  My new tool is far better for the job as far as I'm concerned.  I'll probably play with their tool later this spring, at the end-of-season cleanout, to make sure the paths are really clean.  On a weekly basis, it's easier to just use my "articulating poker".  Which I'll post a pic of if anyone's curious.  It's just a couple of pieces of the removable metal frame you find inside filing cabinets, the sort used to support "hangfiles".  The L-leg and one straight section, if reassembled with a bolt(or rivet) to make a really long L, is perfect for jamming up and down in the tubes.  The bottom leg of the L is just right for chipping away at creosote up the edges, and with a little practice you can really work away at it.

5 out of my 7 heat exchange ducts clogged.  I used a rod for a chimney brush to clear a path for the chain that came with the boiler.  Dropped the chain through and unplugged each easily.  I'm glad I read this post to realize that all 7 are supposed to be clear.  I thought at first they connected into a single duct on each side and so that it was normal to not be able to get the chain through all 7.

Figured I'd post an update.  Finally got the chain tool through all 7 passages.  Didn't improve performance, but now I know they're clear.  Took a lot of chipping to get numbers 5 and 6 clear, and they seem to be clogging back up more quickly than the rest.  Day after I started up for the fall, I was standing near the furnace piling wood, and I heard a "Whumpfh" at the end of a 50 second boost.  Sure enough, the electrical cabinet has a new load of embers in it, so I applied another load of WD40 to the solenoids; pretty sure that's what's happening, one or both valves is hanging up and as a result we get an explosive gas mix in the stove, which relieves itself.  Hope it's not doing any other harm.

Further update, two cleanouts since my post on the 7th, and each time, putting the chain tool through was a breeze except for the sixth tube, which clears quickly but not without some back-and-forth with the tool.  My complaint last year about the tool was unwarranted, it does a decent job as long as you don't forget it exists.

I have an e1450 and the H-Tool that was provided with it does a great job.  A couple years ago the exchange became very clogged and I had to clean it out with a bent piece of 1/4" metal dowel and a bent piece of flatstock.  I ended up getting the H-Tool stuck and the lower wire ring broke when I tried to pull it down.  Fortunately I had the top chain in-tact to extract the tool.  I ultimately replaced the wire rings with heavy duty chain links.  I'd recommend other e1450 owners do the same. 

If the boiler is running efficiently, my exchange doesn't get much build-up (even when burning soft woods).  When the primary air intake gets some build-up and/or the air tubes, thicker emissions eventually accumulate everywhere.  Once its starts running inefficiently, the process compounds itself and everything becomes a pain to clean.  Key is to stay on top of the little things before they turn into bigger problems.

I echo this for any gassers.  As long as intake and exhaust are clean and clear everything runs great.  Once buildup starts anywhere, things get bad in a hurry.  There is very little room for tolerance with sticky mechanisms or plugged airways.
