I have a Pocono I purchased from Rodger at Stoyell's 5 years ago! They are great people, great service, and go out of their way to accomodate bulk coal pick up and delivery!
My Pocono is the 90K BTU model, back vent with a 12 inch duct top, the 110K BTU like yours didn't come out til a few years after I bought mine! But bottom line, its a great stove, and the coal-trol is great! I don't have mine hooked in the most efficent way, its ducted to the hot air side of my oil forced hot air furnace, and I just let the stove's 2- 265 cfm blowers push heat throughout the registers!
The house is a 1850's 2100 square foot farm house located on the ridge between Owasco and Cayuga lakes! Can you say Wind? The house could be tighter, but has mostly new windows, and 12+ inches of insulation on the attick. Could be better, but not bad! When its very cold and Windy, I do run the oil furnace at the same time to supplement, but it really uses minimal oil.
In the 5 years we have had the stove, we have only burned 1/4 tank of fuel oil! I burn between 4 1/2 and 5 tons of coal per year depending the year. I don't think thats to bad considering my set up! I have the coal-trol set point temp set at 69 for both day and night, we found that work's the best with our setup.
As far as the feed rate, the LL default settings for teh coal-trol are 6 min, 40 max. I installed mine myself, so I had to experiment a bit. I found I had to turn my max FR down to stop from getting burning coals pushing of the grate when the feed rate is at max (99). For me I have the max FR set at 29, and that seems perfect! Hot coals stop about an inch back from the end, with not to many un burnt coals falling off! From what I have read, the max FR will vary depending on many factors!
The stove has been flawless! I shut it down durning Christmas break, vaccume the fly ash out of the pipes, stove body and great. I also oil the motors as well. When te season is over, I clean it again, vaccume, take stove pipe off, clean everything with baking soda and water, and oil the motors.
It has never one time jammed or plugged up! The LL feeder system, with the coal-trol is hard to beat! Combine a well designed and simple feeder system of the LL stokers, the coal-trol, and the great service of Stoyell's, you will be satisfied
