Hello Iowaboy, welcome to the forum,
I did a google search for the 'Ashley Model CAC' stovem it is about 48,000 BTU, which may not be enough to keep a 1200sqft house warm on a -0* windy night in Northern Vermont.. It definitely would do the job most of the time, provided your house has decent insulation and windows. Distribution of heated air through the house will be important.
If the stove doesn't have any broken grates, or shaker grate linkage and no apparent warped panels or indications of the stove having been overfired, then you are probably Ok with the stove,, the price is certainly not too much... $200 is reasonable if it is in good shape.
In general the US stove products are more for ocassional use, and not for use continously near their maximum heat output. They are a bit 'light-duty'.. As long as you don't run it near the max all the time,, it should be a good first stove or supplemental heater. What type of chimney do you have, and how tall is it?? A good chimney and a barometric damper are 'must haves' to burn coal in a hand feed stove.
If you can, get to a Harman stove dealer, and look at a Harman Mark I, Mark II, or Mark III,,, they are very heavy duty, made burn near their max output for days/weeks on end...
For getting coal,, check with your fuel suppliers,, propane and oil suppliers and farm/fleet stores, I'm sure you will find someone who brings in bagged anthracite coal,, probably Blaschak coal,, it will cost you around $300/ton I'd guess. The US Stove .pdf manual says that the CAC should only burn 'stove size' anthracite coal,, You will do fine with nut size and maybe even mix of nut and pea size coal. Stove size is huge for this size stove.
Read through this forum,, there is a wealth of information, just takes time to read through it.
Hope this helps... Greg L
