I've had this CB boiler since 2011 (Installed in November, plumbed and on-line in January 2012). After the first (half) season of use, I developed cracks along the sides where the air enters through the holes in the burning chamber. I contacted my dealer in December od 2012 as soon as I noticed it and he said that CB wanted him to send a welder out to repair it, but the boiler needed to be shut down. Since it was the middle of the burning season, he told me it could wait until spring shut-down.
Once spring arrived I got busy with hay, and everything else and didn't contact him again until August of 2013. At that point, the dealer changed their tune and told me that it didn't hurt anything; that it "actually allows more airflow" into the burn area. The boiler was working fine, so I took his advice and forgot about it.
The problem, as it turns out, is not only does it let air in better, it allows creosote to get into the air chambers easier and eventually clog everything up! The problem is, it's near impossible to clean these areas out. I see that CB makes a kit that (to my understanding) replaces these areas with removable plates which would allow you to clean the areas easier and (assuming they warp/crack again) replace them...? The "kit" is "Kit, Air Channel Repair" P/N 2500006, but none of the sites I've visited have a picture of it and my dealer doesn't seem to have heard of it.
Has anyone here:
1. Had the same problem?
2. Repaired it with the CB kit?
3. Come up with a better repair?
Any information and photos (I know Photobucket sucks at the moment) it would be greatly appreciated!
Thank you!
