You've been behind me all the way through this...I sure appreciate that.
Thanks for your time and advice while on the phone with me also.
Will finish up my first batch of coal sometime tomorrow. It was 100# of rice I bought to have for start-up.
It was of poor quality in my opinion. Too much shale...I believe, perhaps it was re-claimed...it has plenty visible small root like twigs throughout and plenty of nonburnable in the ash.
I'll be weighing the ash to get a percentage calculation.
I have 200# from another supplier that I'll be trying next...it looks a lot nicer than that first batch.
So far, with this down-draft design firebox, I am seeing very low stack temps and I do get a decent Gravity Hot Air Flow between blower cycles.
So far, only control wiring I've done is run 2/conductor T'stat wire from Feed Controller to existing relay in H/P for the Emergency Heat...I'm using existing H/P T'stat in Emergency Heat Mode for Coal.
So far, T'stat holds steady on 70*...it works in one half degree increments...no over or under runs of set point...real tests are to come though.
Will I need to make re-adjustments w/ a different quality of coal?
