I have searched this site and have not found my answer so I am throwing the question out there. I have an FMI Windsor see through wood burning fireplace that really does not burn too well and also throw off a lot of smoke when the doors are open. We would like to possibly install an insert taht would be loadable from one side. The other side would not need a door. JUCA used to make such an insert but they appear to be out of business. Any other manufacturers of such a product? Would welcome any other suggestions/advise. Thanks!
