Okay, first, where are you sensing the hot air flow to turn on the blower? You will have to check with the CoalTrol Guys on that, that;s the problem with the furnance blowers, they are not variable speed, and it just tell the blower to come on/off. That is one reason I stayed with the built in blowers on mine,so it keeps a more constant heat/speed output.
Maybe post a pic of your setup.
The Condensation is from fumes getting into the hopper, probably low draft, I just went thru this with mine. Turn you min up to 8 or 10, that will get the idle temps up 20-30 degrees to keep it drawing up the chimney better, once it gets colder outside, you shouldn't have a problem.
Any thing else, just ask!!
