For AHS owners there is confusion here, as they all come from the factory set at 140 degrees, but the manual never once mentions operating them at 140 degrees and instead says to set them at 130 degrees for normal operation, and to lower them to as low as 120 degrees (but never lower) during times of light demand.
There appears to be a permitted level of operator flexibility based upon weather conditions here, with 130 degrees representing the safe middle ground. I now have mine set back to 130 degrees. I'm burning a monitored average of about 36.5 lbs. per day over one full month of collected data. I've noticed little to no difference in the operation or ash characteristics at thermal ash grate settings of 130, 125, or 120 degrees. There is a high level of what appears to be unburned coal among my ashes.
Per my spreadsheet I have been consuming on average 2.14 lbs. of anthracite pea per "degree day" from October 14th through November 13th (today).
