First I suggest you contact a local company that specializes in this style of wood burning stove for an ON SITE inspection. You actually have no idea at this point weather the unit is safe to use or not and that would be nice to know before you have a problem/start a fire.
The interior of the unit many need some consumable parts so see below.
Stove Parts Plus: Model F-8200 Wood Furnace (http://www.stovepartsplus.com/Merchant5/merchant.mvc?Screen=CTGY&Store_Code=SPP&Category_Code=ASH-F-8200)
This is the web site for the manufacturer of your stove. No manual listed probably because your unit is older but you may try to call them.
NOTE: While the service technician is at your home inspecting your wood burner for safety and also making sure the chimny has had its annual cleaning you may ask them how to operate your wood stove properly. Always remember safety first especially when it comes to wood burning.
