I have an Ashford 30.1 that I've had since February 2016.
I've been starting to have problems with my cat clogging. Last night marks the second time in about 2-3 weeks. Basically the stove runs like it is on a lower thermostat setting when it is opened up wide open. I haven't had luck trying to run it hot to burn itself out of the clog. I brushed the face with a soft brush to unclog it the last time, but I could see that there was still more ash deeper into the honeycomb. I could not get my vac in position to do any good. It looks like some compressed air would be just the thing, but I've seen the book says not to. Any suggestions?
Also, my cat has never really seemed to be that great, but it has no visual defects similar to the images in the book. It often stalls around the time the wood is about the the size of charcoal briquettes. I've had half a mind to try it for warranty a couple times.
Yes, I've got two year seasoned dry wood, a tight door, and tight bybass.
One more thing, a few times this year my stove has burned significantly hotter than the stat setting I put it on. I wake up and the house is super hot, I just barely turn the stat knob left and I hear the click of the stove shutting down right away. Any chance my stat inner-workings is getting partially seized up or something? Maybe my wood is too dry? I've had readings of 11-13 on the inside of fresh splits.
Thanks for the help guys.
I found that I could clog the steelcat in one of my Ashfords after just a few hours of burning it on a high setting. I cleaned and re-clogged it several times, very repeatable. On lower settings, it never seemed to clog, and so my theory was that turbulence generated by my very tall (30 feet) chimney would stir up enough fly ash at higher burn rates, to cause the problem.
I checked my draft, and found it was running around 0.18”WC on a high burn, whereas BK spec’s 0.06”WC maximum. I installed a key damper, and used that to dial the stove down to 0.05”WC on a high burn, before I’d set it to whatever burn rate I intended for that load. It seemed to work great for the rest of that year, and I experienced no more clogs for the remainder of that year using the original SteelCat.
This year, I noticed the cat was starting to fade and was due for replacement, I probably had close to 15,000 hours on it. I replaced it with a ceramic cat, which I figured might be even less prone to clogging due the larger passages, but I’m not really sure that is true. Either way, I’m still using the key damper to dial the stove to an ideal 0.05”WC on a high setting, and have had no further trouble with cat clogging.
BKVP’s comment about adjusting the door has me embarrassed. I have never touched the door adjustment on either of my stoves, and I have over 30 cords thru the pair of them. I’ve asked before how one checks the tension on this stove, the dollar bill test doesn’t seem to work like it did on my past stoves, given the overlap in the castings. One stove is noticeably tighter than the other on door handle feel, but both achieve my desired burn times without any issues. If there is a written procedure for checking door tension on an Ashford, I’d appreciate someone posting it, or maybe I need to dig out the manual and see if I just missed it in there. I did NOT use it for my first fire, Chris. :lol
