I have had conversations with ProFab, have had some help, no real long term solutions. the boiler burned a full load last night and it was 38* this morning, at least there were enough coals so I only needed kindling and a little torch to get thing rolling. I have not purchased the flue active tool as I feel they should supply it with the boiler as it seems that the build up problem is their problem( my problem) and they don't care. I understand that tools wear out and I need to pay for replacements but they should supply the first ones with the boiler. The charcoal issue has pretty much gone away from plugging the tubes after i changed the airgate but now I get alot more ash under the nozzels, I actually cleaned the center out on Wed this week also as it had almost filled the center same as this morning. I miss my old Aqua therm it burned alot of wood but it was pretty much maintanence free and would hold a fire for 18 hours or longer if you filled it. It's raining today so no wood cutting today I guess I'm going to have to buy a load of wood this week to get by.That stinks when you have woodd of your own. I wish all of us user were not so far apart so we could get together. Have a Happy Easter, Jim
