Value of a Arrow wood burning stove insert

I'm from Prince George, BC, Canada. I've been searching the web to see if I can determine the value of a older Arrow wood stove insert. From the registration plate it appears to be from somewhere around 1981, as that is when it states that is was tested. It shows a model number of 2200-A. The attached picture is nearly identical to what this unit looks like. This unit has a fan. This unit is in extremely good shape, as it appears it hardly has been used. This unit would have been installed when this house had its basement rumpus room built. Here in prince george homes; are heated by natural gas; therefore this unit probably was only used in winter when the rumpus room was used. This past 15 years the house was owned by my mother. She never used it. She has since passed on and I now own the house. I want to remove this unit and replace it with a natural gas insert. Therefore; that is why I would like to know roughly what its value is. It is not CSA ( Canadian Standards Association) approved, there insurance companies would probably not insure the structure that it would be installed in. That restriction would have a lot of determination of what its value is. Thanks in advance.
