unlabled gas stove rebuild

Hi everyone

Recently I bought a unlabled cake baking gas stove from Taiwan and brought it back to Vancouver. I was hoping to use it to open up a business in the mall. When I called the gas company to my house to install the binding to the propane, they told me that they won't be able to install it because it doesn't have any lable or any product specs informations. They also told me that I won't be able to use it in the mall because i won't be able to get the insurance without the inspection.

My question is how can I deal with this kind of the situation? Is it possible to call the gas contractor to rebuild this gas stove and get the proper inspection from BC Safty Authority? Please help me. Thank you very much.
