I got this stove given to me and I was wondering if anyone knows what model it is? I think it is a lopi answer but not sure because I downloaded the lopi answer PDF manual and the insides were a lot different than mine. The one I have doe not have any firebricks on the top like the manual showed and the manual also showed secondary air tubes witch mine does not have. Is my stove supposed to have this stuff or is it missing? and also is it worth the money to repair it or not any help will be great.
