I have set my ashing at 130 since Sunday night with the 5 degree differentialit was at 120 leading up to this point. Upon the initial firing I had a really good bed of red coal going. Since then I know I have a fire but I can not see any red in there even when the blower is running. It looks dead. Temps say otherwise. I am dropping 80 to 100 pounds a day through it and I am getting mostly unburnt or partially burnt coal in my ash pan. I picked up 6 bags of Blaschack today, I am going to let my hopper run low and re fill with that and see if there is any difference in performance. I checked my manometer pipe and tube, both are clear. I have a draft of .02 now which is an improvement. If I am home tomorrow due to bad weather I am going to open all the windows and heat the great outdoors and see if I don't have a decent base fire going. The last thing that Darren mentioned to me was to re wire the asher to the blower so it only runs when the blower does. Lastly, I still have my old Extrol 30 if I have my plumber run that as well as the 60 I have now would that be sufficient amount for expansion or do I just need to go up to the 105? Thanks yet again, Ken
what are your outside temps there?

It is imperative to get the ashing motor wired to only run when blower runs.:!:
This would definitely reduce daily coal consumption.

If need be, I could describe to you the wire changes. ;)

My understand of wiring the ahser to run only when the blower was running was that is in response to folks having a puffback issue. I haven't had any puffbacks yet but the way things are going they are probably in my future as well. The Blashack made no difference.
fire is out again tonight after 2 days run time. To say this is getting old is an understatement!

This blower and ashing motor factory wiring is a bit of a puzzle, it seems.

I believe member *lsayer* ashing motor was factory wired to come on only w/ fan.

And member *dchartt* wasn't, but he solved both puff-backs and his unburnt coal problems when changed to only run w/ fan and lowering the SV.

In a PM to you I included some more info. about the out fires and excess coal consumption. :)
