If you haven't had your chimney inspected by chimney sweep or other qualified professional its certainly a good idea however you don't have to make this a yearly ritual. If you want to be on the safe side maybe every few years but I guess that depends on the condition and age of your chimney. Just for reference our chimney was installed 25 years ago when the furnace went in, it hasn't been swept or inspected professionally since then. We do "inspect" it every year by using a mirror to make sure there is no obstructions but that's about it. If by any chance we get up on the roof we'll check it from there but thats really rare. I should also note our chimney is on the outside of house and not directly inside the house.
You will have to remove the flue pipe once a year and clean the fly ash out of it and the bottom of your chimney.
FYI you may want to consider running it year round if you have the water coil. You'll use roughly 1 ton for 3 months, depending on the cost of the coal where you live you may very well break even. You will definitely extend the life of the unit. I'm betting many of the units being sold today that are burned year round wlll outlive the use of coal for heating.
